Lifetime Warranty

Every Aydins ring is covered by a lifetime warranty against manufacturing defects. If something fails because of how the ring was made, not how it was worn, we'll take care of it through our warranty process.

What's Covered

• Manufacturing defects in the ring or its finish
• Premature failure of plating, coatings, or inlays under normal wear
• Stone setting failure caused by the manufacturing process
• Defects in the metal or material itself

What's Not Covered

The warranty covers how we built the ring, not what happens to it after you take it home. The following aren't covered:

• Damage from drops, sharp impact, or excessive force
• Wear caused by chlorine, harsh chemicals, abrasive cleaning, or improper care
• Lost rings
• Damage from at-home sizing or resizing attempts (always use the Lifetime Sizing Program)
• Normal cosmetic wear over time on softer metals (small scratches, patina)

Aydins Lifetime Sizing Program

Your finger size will change over the years. The Lifetime Sizing Program is how we make sure your ring keeps fitting, no matter how long you've owned it.

It works like this:

• If your size changes at any point in your life, we will send you the same ring in your new size for a small re-sizing fee, not the full retail price.
• You ship your original ring back to us, and we ship the replacement out to you.
• The full process is handled through our Returns & Exchanges portal, so you can track everything from start to finish.

The exact process depends on the metal (some can be resized, others are replaced), but the outcome is the same: you stay in a ring that fits, for life.

How to File a Claim or Request a Resize

Visit our Returns & Exchanges page to start any warranty claim, resize request, or return. You'll be guided through our self-service portal, where you can submit your claim, upload photos if needed, and track status from start to finish.

For warranty claims, please include a clear photo of the ring so we can confirm coverage before shipping a replacement.

Our Promise

Aydins has been making rings since 2011. The warranty and the sizing program exist for one reason: a wedding band is supposed to last as long as the marriage. We build the ring to do that, and we back it for as long as you wear it.

What Black Zirconium Is

Black zirconium is a metal that's been heat-treated to create a permanent black surface. The process works like this: a polished zirconium ring is fired in a high-temperature kiln (typically over 1000°F), which causes the surface layer to oxidize into zirconium dioxide, a ceramic-hard black finish that's chemically bonded to the metal underneath. The black isn't a coating, plating, or paint. It's the metal itself, transformed.

Zirconium is the same family of metals used in nuclear reactor cladding and medical implants, chosen for its exceptional corrosion resistance. For wedding bands, it produces one of the most durable black finishes available, period.

Why People Choose It

• The blackest black, and it stays that way. The black surface is fused into the metal at the molecular level, so it can't chip, peel, fade, or wear off the way plated black finishes eventually do.
• Surface harder than tungsten. The zirconium oxide layer rates about 9 on the Mohs scale, harder than the underlying metal and harder than most steel. It resists scratches and holds its finish under daily wear.
• Lightweight. Zirconium is significantly lighter than tungsten, closer to titanium in feel. Comfortable for all-day wear.
• Hypoallergenic. Zirconium is biologically inert. It's used for joint replacements and surgical implants for the same reason.
• Corrosion-proof. Doesn't rust, tarnish, or react with chemicals. Saltwater, chlorine, and sweat don't affect it.

The Tradeoff Worth Knowing

The hard outer oxide layer is what makes black zirconium special, but it's also what creates the trade-off. The layer is thin (measured in microns), so a deep gouge from sharp impact can expose the lighter zirconium metal underneath. This is rare in normal wear, but worth knowing.

Two practical notes:

• It can be cut off in an emergency. Unlike tungsten or ceramic, the underlying zirconium metal can be sawed through with standard ER tools.
• Resizing isn't possible. Resizing would crack the oxide layer. If your size changes, we replace the ring through the Aydins Lifetime Sizing Program.

Comfort Fit, Explained

Every Aydins black zirconium ring is built with a comfort-fit interior. The inside of the band is gently domed instead of flat, which reduces friction against the finger and makes the ring sit smoothly even when your hand swells slightly (heat, humidity, exercise, long flights).

One note on sizing. Comfort-fit rings often run a half size larger than standard fit, so if you've measured for a non-comfort-fit ring before, order a half size down. If you're unsure, our Ring Sizing Guide has three different ways to find your size at home.

Finishes

Black zirconium accepts a range of surface treatments before the oxidation process: high polish, satin matte, brushed, sandblasted, or hammered. Many of our black zirconium rings also feature inlays of contrasting materials (gold, rose gold, koa wood, antler, meteorite) which create a striking visual contrast against the deep black surface.

Care & Cleaning

• Clean with mild soap and warm water, dry with a soft cloth.
• Skip the ultrasonic cleaners and chemical jewelry dips. The oxide layer doesn't need them.
• No special precautions for showering, swimming, or normal household chemicals. Black zirconium is inert.
• Avoid hard impacts against rough surfaces (concrete, brick, granite countertops). The hardness that resists scratches is the same property that makes the oxide layer vulnerable to deep gouges.

Lifetime Coverage

Every Aydins black zirconium ring is backed by a lifetime warranty against manufacturing defects and the Aydins Lifetime Sizing Program. If your size ever changes, we get you into a ring that fits through the sizing program. Both are handled through our Returns & Exchanges portal, and the full warranty terms are listed on the Warranty tab.

The promise behind both is simple: a wedding band is supposed to last as long as the marriage. We build the ring to do that, and we back it for as long as you wear it.
