Home › The Jewel School › Precious Metals › Black Titanium Ring Care

Before you can care for a black titanium ring correctly, you need to know what it is actually made of — because the three types of black ring sold under the "black titanium" name are made differently, wear differently, and fail differently. The first type is PVD or DLC coated titanium: a separate black layer applied to the surface of a titanium ring. The second type is anodised titanium: titanium whose oxide layer has been thickened by electrical current to produce a dark colour — but not a true, permanent black. The third type is black zirconium: a separate metal, not titanium at all, heat-treated to convert its surface into an integral black ceramic oxide layer that is part of the metal itself. Azarai sells only black zirconium rings. We do not sell PVD-coated black titanium rings and we do not sell anodised rings marketed as black. The reason is simple: black zirconium is categorically more durable than either alternative, and this guide explains why — and how to care for all three so you understand what you own.

What Type of Black Ring Do You Have?
Black zirconium → Integral oxide — the only type Azarai sells

PVD/DLC coated titanium → Applied surface layer — not sold by Azarai

Anodised titanium → Dark colour only, not true black — not sold by Azarai

Most durable of the three → Black zirconium — no contest

Three Types of Black Ring, Three Different Materials

The market sells all of the following under the name "black titanium." They are not the same material and they do not behave the same way.

Black Zirconium — What Azarai Sells

Azarai Standard
Zirconium is a metal — not titanium, but a close chemical relative with similar weight and toughness properties. When zirconium is heat-treated at around 700°C in an oxidising atmosphere, its surface converts into zirconium dioxide (ZrO₂): a ceramic-like compound that is black, hard (approximately Mohs 8) and chemically bonded to the metal. The black is not applied to the zirconium — it grows out of it. The entire ring is zirconium throughout: the outer surface is oxidised zirconium (black), and the core beneath it is unoxidised zirconium — a dark grey metal. There is no colour contrast between surface and substrate in the way there is with a coated ring, because the ring is one material in two states of oxidation. The black oxide layer does not chip, peel or delaminate because there is no separate layer to fail.

PVD and DLC Coated Black Titanium — Not Sold by Azarai

Not sold by Azarai
PVD (physical vapour deposition) and DLC (diamond-like carbon) coatings are genuine industrial processes that bond a thin black layer to the surface of a titanium ring. The titanium substrate beneath is silver-grey; the black colour is entirely in the applied coating. These coatings are hard and durable relative to other coatings, but they are a separate layer sitting on top of the metal. Under sufficient abrasive wear or direct impact, the coating can scratch through to the silver-grey titanium beneath — producing a high-contrast mark that is not repairable at home. Re-coating is possible but requires stripping the old layer and reprocessing, which is a specialist procedure beyond routine maintenance. Azarai does not sell PVD or DLC coated black titanium rings because the durability gap between coating and integral zirconium oxide is too large to ignore.

Anodised Titanium — Not Sold by Azarai as "Black"

Not sold by Azarai as black
Anodising grows a thickened oxide layer on titanium by passing an electrical current through it in an electrolyte solution. The colour produced depends on the voltage used — different voltages create different oxide thicknesses, which refract light to different colours. Anodising can produce blues, purples, bronzes and dark grey tones. It cannot produce a true, permanent black. What is sometimes sold as "anodised black titanium" is a very dark grey or dark bronze at best, and the colour is also the least durable of the three options: the oxide layer from anodising is thinner than zirconium's heat-oxidation layer, and the colour fades and shifts under sustained wear — particularly on the inside of the ring where contact with the finger is constant. Azarai sells anodised titanium rings in genuine anodised colours (blue, purple, bronze) — we do not market anodised rings as black titanium.

Why Azarai Only Sells Black Zirconium

Our Position
We are asked regularly why Azarai does not stock PVD-coated black titanium rings, which are significantly cheaper to produce and dominate the online market. The answer is straightforward: we only sell pieces we are confident will look good to a buyer in five years, and PVD-coated black rings do not consistently meet that standard under Nigerian daily-wear conditions. The heat, sweat and active lifestyles of our Lagos and Abuja buyers accelerate surface coating wear faster than cooler, less active markets. Black zirconium's integral oxide layer is in a different durability category — the same material that makes it black is the same material that makes the ring hard, and neither property diminishes under the conditions our customers actually live in. When we recommend a black ring, we are recommending something we stand behind. That means black zirconium only.

Storage: The Most Important Habit You Will Build

The rule for storing any black ring — zirconium, coated or anodised — is the same: store it alone, in its own soft pouch, never in contact with other jewelry or hard surfaces. The reasoning differs slightly by type, but the rule does not.

For black zirconium, abrasive contact in storage wears the oxide surface layer. The black oxide is hard at Mohs ~8 — harder than most jewelry metals — but diamonds (Mohs 10), sapphires (Mohs 9) and even tungsten rings (Mohs ~9) will score it with sustained contact. Because the oxide layer is the same material throughout, deep wear does not produce a sudden colour change — it produces gradual lightening of the surface in the affected area. Prevention through correct storage keeps the ring looking uniform for years.

For PVD or DLC coated black rings, the stakes are higher: the coating is thin, and abrasive contact in storage can cut through to the silver-grey titanium substrate, producing a high-contrast bright mark against the black surface. This is visible and not repairable at home.

For anodised titanium, storage contact accelerates the colour fade that would happen anyway — just faster and less uniformly, producing patchy dark-grey areas rather than an even gradual shift.

The Individual Soft Pouch — Always, Every Time

Non-Negotiable
Azarai includes an individual soft pouch with every ring purchase. When the ring comes off the finger, it goes into the pouch. Every time — not most of the time, not when you remember. The habit takes two seconds and prevents the most common cause of damage to a black ring entirely. Keep the pouch on the bedside table. Keep a second one in a desk drawer. Pack one in the travel bag. The ring should never rest on a surface, in a drawer or in a jewelry box without the pouch between it and everything else.

What Never to Store It With

Avoid
Diamond jewelry — Mohs 10, will score any ring surface on contact. Sapphire, ruby and emerald pieces — Mohs 9. Tungsten rings — Mohs ~9. Ceramic jewelry — Mohs 7–8. Hardened steel watch cases and clasps. Even other black zirconium rings loose together will produce surface wear over time through metal-on-metal contact. Gold and silver pieces are softer than the zirconium oxide surface and less likely to cause damage — but they almost always carry stones that are not. The rule is simple: nothing touching the ring in storage except soft fabric.

Travel Storage

Travel
Travel is the highest-risk storage moment for a black ring. A ring dropped loose into a toiletry bag with keys, coins or other jewelry can accumulate significant surface damage before the flight lands. Always travel with the ring on the finger or in its soft pouch in a dedicated pocket. For buyers travelling with multiple pieces, a small travel jewelry roll with individual fabric-lined pockets for each piece is the right solution. Black zirconium is unaffected by X-ray machines, cabin pressure or humidity changes — the travel risk is entirely about physical storage, not the travel environment itself.

Daily Wear: What Is Safe

Black zirconium's underlying metal is as corrosion-proof and chemically stable as titanium — it does not tarnish, react to moisture, or degrade in humidity. The black oxide surface is equally stable. The following are all safe without removing the ring:

Showering and bathing. Water and soap are completely fine. Rinse well after each shower — soap film on the black surface dulls the appearance temporarily and is the most common reason buyers think the ring is losing colour. It is not losing colour; it is dirty.

Swimming. Chlorinated pools and salt water produce no reaction with zirconium or its oxide layer.

Sweating in Lagos or Abuja heat. Sweat does not affect zirconium.

Hand sanitiser. Alcohol-based products are safe on all three black ring types.

Cooking and kitchen work. No concerns.

Perfume and cologne. Accidental spray contact is fine. Avoid making a habit of spraying directly onto the ring, but it is not a damage risk.

Remove the ring for heavy gym work involving gripping bars under load — this is a finger safety issue (ring avulsion injury risk), not a ring protection measure. Remove it for any sustained work involving masonry, concrete or repeated hard abrasive contact with surfaces harder than the oxide layer. Normal office and home daily wear requires no removal.

The Correct Cleaning Routine

The routine differs slightly for zirconium versus coated or anodised rings — primarily in what tools you use on the surface.

For black zirconium (Azarai rings):

1. Warm water and a single drop of mild dish soap in a small bowl.

2. Soak for two minutes to loosen surface oil and residue.

3. Clean with a soft microfibre cloth. If using a brush, use only a baby toothbrush or similarly fine-bristled brush — test it on the back of your hand first. If the bristles feel stiff, they are too stiff for the ring.

4. Rinse thoroughly. Soap residue on the black surface is the primary cause of the "going grey" appearance buyers sometimes notice — full rinsing prevents it entirely.

5. Pat dry with a clean, dry microfibre cloth. Pat — do not rub.

For PVD or DLC coated black titanium: The same process as above, but with even more caution about brush stiffness. The coating is a thinner separate layer than zirconium's integral oxide, and even mildly abrasive contact accelerates wear at its edges and high-contact areas. Microfibre cloth only — no brush at all if possible.

For anodised titanium: Mild soap and water with a microfibre cloth. The anodised colour layer is the thinnest and most vulnerable of the three — treat the surface as delicate. Rinsing thoroughly after cleaning is especially important because soap residue on an anodised surface creates visible watermarks that are harder to shift than on zirconium.

What to Never Do — Any Black Ring Type

Never Do | Why — Zirconium | Why — Coated | Why — Anodised
Use a polishing cloth | Abrasives strip the oxide layer — lightens the black permanently | Abrasives strip the coating — exposes base metal | Abrasives remove the thin anodised layer entirely
Use abrasive cleaners | Same as polishing cloth — surface wear | Accelerates coating failure at edges | Removes colour layer immediately
Use toothpaste | Contains abrasive particles — scratches oxide | Strips coating over time | Strips colour layer
Use bleach | Can chemically discolour ZrO₂ surface | Can react with coating chemistry | Strips anodised colour layer rapidly
Use ultrasonic cleaner | Vibration degrades oxide layer over time | Lifts coating at edges | Removes anodised layer
Store with other jewelry | Abrasive contact wears oxide surface | Hard contact cuts through to base metal | Contact removes thin colour layer

If the Surface Gets Scratched or Wears

What happens when a black ring surface is damaged differs entirely by type — and the outcome for zirconium is meaningfully better than for the alternatives.

Black zirconium: Because the ring is zirconium throughout — black oxidised zirconium at the surface, dark grey unoxidised zirconium beneath — wear produces a gradual shift from deep black toward dark grey rather than a sudden sharp colour change. There is no contrasting base metal to expose. Light surface wear over years of honest daily use produces a ring that has evolved rather than one that has failed. For deeper scratches or for buyers who want the ring restored to its original deep black, re-oxidation is possible — a specialist process where the ring is cleaned, prepared and re-heated to re-grow the oxide layer. Azarai assesses and facilitates re-oxidation for black zirconium rings purchased through us.

PVD or DLC coated black titanium: A scratch that cuts through the coating exposes the silver-grey titanium substrate beneath — a bright, high-contrast mark against the black surface. This is not repairable at home. Re-coating requires stripping the old layer first, which is a specialist procedure. The damage is also more binary than zirconium wear — the ring looks fine until the coating fails in a spot, then it looks obviously damaged.

Anodised titanium: The colour layer is so thin that surface wear produces fairly rapid fading and colour shift — from dark grey toward the base silver-grey titanium, and often unevenly, with the inside of the ring fading faster than the outside. There is no repair — the anodised colour cannot be restored without re-anodising the entire ring, and a re-anodised ring will never achieve a true permanent black.

Nigeria Context
What This Means for Nigerian Buyers

The Nigerian market for black rings has grown significantly in the last three years, and the majority of what is available online — from international retailers shipping to Lagos and from local resellers — is PVD-coated black titanium, not zirconium. This is a price reality: coated rings are cheaper to produce and the difference is not obvious in a photograph. For buyers in Lagos and Abuja conditions — daily heat, active lifestyles, the reality of communal jewelry storage in many households — the durability difference between zirconium and a coating is not theoretical. Coated rings that might last eight years in a cool climate with careful handling can show surface wear within two to three years of Lagos daily wear. Azarai made a deliberate decision to stock only black zirconium rings, and we are transparent about this because we think Nigerian buyers deserve to know what they are buying. The communal jewelry storage point is also specifically relevant here: a black zirconium ring stored loose in a shared tray will wear less dramatically than a coated ring in the same situation — but it will still wear. The individual soft pouch is not optional for a black ring in any Nigerian household where jewelry is kept communally. All Azarai black zirconium rings come with a dedicated storage pouch and a 7-day size exchange if the fit is not right.

Frequently Asked Questions

What is the difference between black zirconium and black titanium?

They are different materials. Black zirconium is a zirconium ring heat-treated to convert its surface into an integral black ceramic oxide layer — the black is part of the metal. Black titanium is titanium with a black PVD or DLC coating applied to the surface — the black is a separate layer on top. Black zirconium is more durable: the integral oxide does not chip or peel; the coating on black titanium can fail under sustained wear. Azarai sells black zirconium rings only.

Why is my black ring looking grey?

For black zirconium, a grey appearance is almost always soap film or skin oil residue on the surface — the oxide layer is deeply absorptive and a thin film on top significantly reduces the apparent depth of the black. Clean with mild soap and water and rinse thoroughly; the black depth restores immediately. If the ring still looks grey after cleaning, bring it in for assessment — persistent dulling can indicate surface wear, but this is uncommon with correct care.

Can I use a polishing cloth on my black ring?

Never. Metal polishing cloths contain abrasive compounds designed to remove surface oxidation. On a black zirconium ring, they will strip the very oxide layer that produces the black colour — permanently lightening the surface. On a coated ring, they will accelerate coating wear. On an anodised ring, they will remove the colour layer entirely. Always clean a black ring with mild soap and a soft microfibre cloth only.

Does Azarai sell PVD-coated black titanium rings?

No. Azarai sells only black zirconium rings — not PVD or DLC coated black titanium, and not anodised titanium marketed as black. The durability difference between integral black zirconium oxide and a surface coating is too significant for us to offer both and let buyers pick on price alone. If a black ring is purchased from Azarai, it is black zirconium.

Can a worn black zirconium ring be restored?

Yes — through re-oxidation, a specialist process where the ring is prepared and re-heated to re-grow the black oxide layer. This is not a routine jeweler's service and cannot be done at home. Azarai assesses and facilitates re-oxidation for black zirconium rings purchased through us. Bring the ring into our Lekki, Ikeja or Abuja showrooms for an honest evaluation before committing to the work.

Is it safe to shower with a black zirconium ring on?

Yes. Zirconium and its oxide layer are completely unaffected by water and soap. Rinse well after showering — soap film on the black surface is the most common cause of the ring appearing dull or grey, and it is resolved entirely by a thorough rinse. The one product to be cautious of in the shower is exfoliating scrub: the abrasive particles in scrubs should not be rubbed directly across the ring surface.
