[QUOTE="WalnLiz, post: 3788, member: 147"] Sorry to disappoint you Col but spinel and sapphire are two completely different stones. :( Sapphires are gem quality Corundum Al203.... and Spinel MgAl204...is a completely different chemical composition.... Spinels can come in a variety of colours and some are similar to Sapphire...Most coloured stones come from places like Burma and Sri Lanka and only very few are found in OZ. Unfortunately the black variety..." also known as Black jack "... isn't worth much. It is sometimes substituted for Black Onyx in jewelery.... ;) does however polish up really well...Cheers Wal. :) [/QUOTE]
