About the dinosaur bone... The Utah dinosaur gem bone in this ring came from the Colorado Plateau and was a living animal during the Jurassic Period around 144 to 208 million years ago. The dinosaur bone we use in our rings is usually referred to as “gembone”. It is actually not dinosaur bone but is a combination of minerals that replaced the bone structure over time. Dinosaur bone is found in a rainbow of colors with the webbing color and cell size varying greatly from piece to piece. The varying cell size and colors create some truly unique patterns and virtually one of a kind pieces of dinosaur bone jewelry. The fossilized dinosaur bone can be composed of many different minerals including agate, jasper and calcite. The gembone color is determined by the combination of minerals present when the fossilized bone formed. Some colors are more rare than others with multicolor cells in a nice pattern being the most sought after. High quality dinosaur bone has a hardness of 6-7 on the Moh’s scale. Top grade gem dinosaur bone is eventually going to become impossible to get because, as you might have guessed, they aren’t making it any more. About the lab created opal... The lab created opal in this ring is a top quality synthetic opal grown under laboratory conditions. The manmade opal's chemical composition is the same as natural opal with the exception of water content. Australian opal contains about 4% water and lab created opal contains no water. Instead the water is replaced with resin. The resin gives the synthetic opal more durability and helps to resist cracking. Laboratory grown opal gives you all the fire and colors of top grade natural opal at a much more affordable price with increased durability.
