These are blue sapphire briolettes on 14 kt white gold. The sapphires I found at one of the gem shows in Tucson. Two necklaces are pictured, one on a small white gold chain with a single large briolette and the other is the majority of the other sapphires suspended on a thicker white gold chain. The earrings were also in white gold with more briolettes. After this set was finished the friend, who will remain nameless, wanted a couple more single sapphires for earrings that would go with the single briolette necklace. The other photo, not very good, and taken with my phone's camera, is of a hand made fine silver tear drop on a white gold chain.
I'll get back to it this week and have some fun Spring things to show off next Saturday.
