Royale Gems Man Made Diamond 2.25 carats White 10KTGold chain Amber Faceted Gem 

This come from an Estate Auction, it did not say the Karat of Gold, so I did a scratch test, it eat the gold on a 14kt gold acid test but it Passed a 10kt Gold acid test,,So it is 10kt White Gold 18'' inch chain

As box shows ''Gold Chain 2.25 carats of Man Made Diamonds by ROYALE GEMS, im assuming that the Amber Gem in the middle is also Man Made but not sure, It feels like Glass so either Glass or Man Made Amber Gem,,i just don't want to be misleading because I don't know how to tell if it is Glass or Man Made, but the diamonds are Man Made

The amber Gem is approximately 11mm in size ''ABSOLUTELY BEAUTIFUL NECKLACE IN BOX, NO SIGNS OF USE OR TARNISH''
