Spinel has long been thought to be a kind of ruby and sapphire, and it is a stone with bright and colorful colors and transparency. It is named after "spina" which means "small moth" because octahedral crystals have sharp corners. Because the spinel crystals are as polished as they are, they are sometimes referred to by miners in the production area as "god-polished stone" or "angel cut". It is a rare piece of such a spinel bright pink crystal that has been carved with marble. A piece of loose spinel crystal is simply knitted up.
