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.
