Minerals are the building blocks of rock. Some rocks consist of just one type of mineral while most rocks contain a combination of minerals. Each mineral has a unique chemical composition which determines what color it will be. Also, interaction with other minerals and environmental factors contribute to its uniqueness. We’re enjoying the serpentine specimen Delvin Leekya chose to carve a sky-watching Bear from. Swirling grey and subtle yellow-green colors exist in the serpentine. Eyes are from turquoise inlays and a double point offering bundle is from iridescent pink mussel shell and turquoise. About 2 1/2″ long, 1″ wide and 2″ tall.
