I made my partner a beluga pendant. I didn't make the parts myself but I put the pendant bale and pendant mounting together and set the stone in the pendant. It's a beluga because it's set with a white sapphire. They loved it.
What my partner doesn't know is that I already have bits and bobs for a matching ring with a blue sapphire, and bits and bobs coming for matching earrings with teal spinels in them.
