Genuine trilobite rings, featuring a fossilized invertebrate that is over 250 million years old, encased in sterling silver. These ancient ocean creatures are arthropods, but have no similar modern relatives, and each animal is unique! Learn more about trilobites here. Please note that fossils this old can be fragile, so the ring should only be worn when it will not get damaged (not while working or cleaning, etc.) These rings were made by a trusted supplier (i.e., are not handmade by me) and I am very lucky to be able to offer them. The first ring shown (1st 3 photos) is US size 8 5/8 (UK size R), with a trilobite that is almost 1 inch (24 mm) long and 4/5ths of an inch (20 mm) wide. The band is 1/6 of an inch (4 mm) wide.

The second ring (photos 4-5) is US size 7 3/4 (UK size P 1/2); fossil is 4/5 of an inch (20 mm) long and over 1/2 an inch (14 mm) wide; the band is 1/6 of an inch (4 mm) wide.

The last ring (photos 6-8) is US size 8 1/4 (UK size Q 1/2); fossil is 2/3 of an inch (18 mm) long and 3/5 of an inch (15 mm) wide; the band is less than 1/6 of an inch (3.5 mm) wide.
