Why Sapphires are not always blue.

White, green, pink, black, grey, violet, etc.  Sapphire comes in many different colors.  A rainbow of colors.  Are they treated or natural?  How can you tell?  What is a synthetic sapphire and how can you separate it from a natural sapphire or an imitation one?  HELP!!!

Help is on the way.  Stay tuned for future postings to get the answers so you can make an educated purchase.
