Here are a few of my favorite custom tanzanite rings that I made.
This bad boy started with a 12mm wide platinum band. I added two platinum “tree trunks” to support an 18k yellow gold trillion bezel that floats above the ring. I was always amazed how heavy this ring felt. Platinum is considerably more dense then gold.
This irregular shaped trillion tanzanite had awesome color. It screamed in this super white gold mounting.
