About Ceramic
Ceramic is a high-tech engineered material. It's harder than steel, lighter than tungsten, and color-stable for life. The ceramic used in the PROTOCERATOPS is engineered specifically for jewelry. It won't fade in sunlight, won't pick up scratches the way coated rings do, and stays glossy with nothing more than a wipe-down.
Ceramic is highly scratch-resistant but brittle under sharp impact. Drop it on tile and it can chip or crack. The upside in an emergency: ceramic rings can be cracked off the finger quickly using standard ER tools.
Ceramic is naturally hypoallergenic with zero nickel content, so the PROTOCERATOPS works for sensitive skin. It's also notably lighter than tungsten, which makes it comfortable for all-day wear.

Sizing & Fit
The PROTOCERATOPS is comfort fit, meaning the inside of the band is rounded rather than flat, which makes it easier to slide over the knuckle and more comfortable for all-day wear. Comfort-fit rings typically size a half-size smaller than standard-fit rings, so if you normally wear a size 10 standard-fit, you'll likely wear a 9.5 in the PROTOCERATOPS.
Available sizes: 5 – 15, including half sizes.
Not sure what size you wear? Use our free ring sizing guide, or order any size and use our lifetime sizing to swap if it doesn't fit perfectly the first time.
Care Instructions
The PROTOCERATOPS's ceramic body is essentially maintenance-free. Wipe with a soft cloth to restore the polish, and use warm soapy water for a deeper clean. Don't drop on hard surfaces (ceramic is scratch-resistant but brittle), don't use abrasive cleaners, and avoid sharp impact on the inlay.
Engraving
Every PROTOCERATOPS includes free inside laser engraving. Add a wedding date, initials, coordinates, or any phrase up to 30 characters. Engraving is permanent, professionally applied, and does not delay shipping.
Frequently Asked Questions
What color is the PROTOCERATOPS?
The PROTOCERATOPS features green.
What sizes does the PROTOCERATOPS come in?
The PROTOCERATOPS is available in sizes 5 – 15, including half sizes. If you're between sizes, lifetime sizing is included, so you can order, try it, and swap if needed.
Is the PROTOCERATOPS comfort fit?
Yes. The PROTOCERATOPS is comfort fit, meaning the inside of the band is gently rounded so it slides over the knuckle easily and sits flat against the finger. Most wearers find it comfortable enough to forget they're wearing it.
Is the PROTOCERATOPS durable for daily wear?
Ceramic is highly scratch-resistant, harder than steel, and color-stable for life. The PROTOCERATOPS won't fade or pick up surface scratches from daily wear. It is brittle under sharp impact, so don't drop it on tile or concrete.
Is the PROTOCERATOPS hypoallergenic?
Yes. The PROTOCERATOPS is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.
Can the PROTOCERATOPS be engraved?
Yes. Free inside laser engraving is included with every PROTOCERATOPS. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.
What if the ring doesn't fit?
Lifetime sizing is included with every PROTOCERATOPS. If it doesn't fit, ship it back and we'll send a different size, even years after the original purchase.
How long does shipping take?
Free standard shipping ships within 1-2 business days from our Irving, Texas shop and arrives in 3-5 business days within the US. Most PROTOCERATOPS orders arrive within a week of ordering.
What is Aydins' return policy?
See our returns and exchanges page for full details.
Can the PROTOCERATOPS be cut off in an emergency?
Yes. Both tungsten and ceramic rings can be safely removed in an emergency. Hospitals use a tool that cracks the band cleanly off the finger without needing to cut through it. This is actually a safety advantage over gold or platinum, which require more time-consuming cutting.

Warranty
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.
FAQ's
How does inside engraving work?
Free with every order. You can engrave text, dates, coordinates, fingerprints, handwriting, signatures, or a custom image. Standard fonts are included; if you want a specific font or custom artwork, send us a sample after checkout and we'll match it. Engraving is permanent and laser-etched, not stamped.
Do you offer custom sizes or widths?
Yes, within reason. We can do half sizes, sizes below 5 and above 15, and non-standard widths on most styles. Reach out before ordering with what you need and we'll quote the timeline. Some materials (ceramic, full-engraved patterns) have manufacturing limits we'll be upfront about.
Which material is right for me?
Tungsten is hardest and most scratch-resistant; great for daily wear and active hands. Titanium is lighter, hypoallergenic, and softer in feel. Ceramic is hard like tungsten but lighter and a true permanent black. Solid 14k gold is softer than tungsten and will pick up character marks over time, which most buyers like; pick gold if you want a traditional precious metal. Each ring's Material tab covers the specifics for that piece.
Are your rings really handcrafted?
Yes. Every Aydins ring is hand-finished, hand-inspected, and hand-engraved in our workshop before it ships. We've been doing this since 2011. That's why standard turnaround is 1 to 3 business days and not same-day; the quality check takes a beat.
