Yes, these are real dinosaur bone rings, made of genuine fossilized bone (often called gembone), set in sterling silver. All 4 rings shown in the first photo are available. When dinosaur skeletons fossilized over millions of years, the spaces from cells were often filled with semi-precious gemstones such as quartz and agate. These rings all have some agate and chalcedony showing. As with all of my other rings, these are not handmade by me, but come from a few of my trusted suppliers. The first ring available is size 7 1/2 (or UK size P), and has the smallest stone, a teardrop 13 mm long by 8 mm across (1/2 x 1/3 inch). The bone contains some orange chalcedony sections surrounded by white lines with brown and black patches.

The second ring is size 10 5/8 (or UK size V), with a stone 25 mm by 12 mm (1 inch x 1/2 inch). The stone is mostly brown with bluish-grey cells and white lines.

The third ring is a hair above size 8 (or UK size Q) and can also be adjusted to be a bit larger as the sides of the bands are separated. The stone is teardrop-shaped, 27 mm by 20 mm (over 1 inch x 4/5 inches). The stone is deep brown with a hint of orange, and has both light orange and pale blue-grey chalcedony in the cells.

the fourth ring is size 7 1/4 (or UK size O 1/2), with a fossil 28 mm long by 12 mm wide (over 1 inch x 1/2 inch). The stone is medium brown with a few darker patches and white (with a bit of pale blue) lines through it.
