Who the MESOZOIC is for
The MESOZOIC is for the buyer who wants something with a story. Real fossilized dinosaur bone, somewhere between 65 and 200 million years old, sliced and inlaid into a wedding band. It's the ring that starts conversations: geology buffs, museum-goers, paleontology fans, and anyone who wants something on the finger that no one else at the wedding will be wearing.
This rare wedding band is 230 years in the making! Expertly fashioned in long-lasting tungsten carbide, the MESOZOIC is nothing like your typical wedding band. The center is inlaid with an authentic mineralized dinosaur fossil that has been cut and polished to a brilliant shine. The coloring is created by the minerals that slowly replaced the bone over millions of years. This particular fossil has a white hue. Both edges are beveled and polished, adding even more shine to this premium wedding band.
- It’s available in a 4mm and 8mm widths.
- You may find rings similar to these style in our dinosaur bone wedding bands collections.
- Because each fossil piece is unique, your ring's pattern will differ slightly from the photo.
- Each ring contains real fossil material so the pattern in every ring is unique.
- Tungsten Carbide is the newest and strongest metal to be used in jewelry.
- It’s four times harder than titanium and twice as hard as steel, giving it high scratch resistance.
- Please note that the inlay is made of a softer material than tungsten and can scratch.

About Tungsten Carbide
Tungsten carbide is one of the hardest metals used in jewelry. It's much harder than titanium, gold, or platinum, holds a mirror polish that doesn't dull from daily wear, doesn't bend out of round, and resists scratching from almost anything you'll encounter day-to-day.
The trade-off is that tungsten is harder than it is tough. A direct hammer-strike or a fall onto concrete from height can chip it. In an emergency it can be cracked off the finger with standard ER tools, which is actually a safety advantage compared to gold or platinum.
Tungsten rings don't trigger nickel allergies, don't tarnish, and don't oxidize. The MESOZOIC holds the same finish years into wear as it has on day one.
About the Dinosaur Bone Inlay
The inlay in the MESOZOIC is real fossilized dinosaur bone, sometimes called gembone. It's the mineralized remains of bone that's been buried for tens to hundreds of millions of years. As groundwater carries minerals through the original bone over geological time, the organic material is gradually replaced by silica and other minerals, locking in the cellular pattern of the original bone in stone.
What you see in your ring is the cross-section of that mineralized bone, with every cell, every blood-vessel channel, and every growth line preserved in color. Color varies by mineral content: red and orange tones come from iron oxides, blue and green from copper or chromium, and grays and browns from manganese and silica. Because every ring is cut from a different piece of fossil, no two patterns are alike.
Care: the dinosaur bone inlay is real stone, durable but treatable like any gemstone. Avoid sharp impacts on the inlay, don't soak in chemicals, and give it a wipe-down with a soft cloth rather than abrasive cleaners. The metal band beneath protects the fossil from everyday wear.

Sizing & Fit
The MESOZOIC 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 MESOZOIC.
Available sizes: 4 – 14, 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
Wipe the MESOZOIC with a soft cloth. That's the core care routine. Tungsten doesn't tarnish, doesn't oxidize, and doesn't lose its polish from daily wear. For a deeper clean, warm water and mild dish soap; rinse, dry, done. Avoid dropping on tile or concrete (tungsten is hard but brittle), and remove for heavy hammer/chisel work.
Engraving
Every MESOZOIC 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 MESOZOIC?
The MESOZOIC features silver & white with a real dinosaur bone inlay.
What sizes does the MESOZOIC come in?
The MESOZOIC is available in sizes 4 – 14, including half sizes. If you're between sizes, lifetime sizing is included, so you can order, try it, and swap if needed.
What width is the MESOZOIC?
The MESOZOIC is offered in 4 & 8mm widths. Both widths are available so couples can match their bands.
Is the MESOZOIC comfort fit?
Yes. The MESOZOIC 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 MESOZOIC durable for daily wear?
Tungsten carbide is one of the most scratch-resistant materials used in jewelry, and much harder than gold, titanium, or platinum. The MESOZOIC is highly resistant to scratches from daily wear. It is brittle under sharp impact, so avoid hammer-strikes or drops onto concrete.
Is the MESOZOIC hypoallergenic?
Yes. The MESOZOIC is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.
Can the MESOZOIC be engraved?
Yes. Free inside laser engraving is included with every MESOZOIC. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.
Is the dinosaur bone inlay real?
Yes. The MESOZOIC's dinosaur bone inlay is real fossilized bone, mineralized over tens of millions of years. Each ring is unique because every fossil slice is unique.
What if the ring doesn't fit?
Lifetime sizing is included with every MESOZOIC. 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 MESOZOIC orders arrive within a week of ordering.
What is Aydins' return policy?
See our returns and exchanges page for full details.
Can the MESOZOIC 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.
