Lab diffused Tanzanite cut into antique cushion facet shape 4.89 carats. The stone changes color depending on the light and movement of the stone on your hand. I was really wanting to keep this one for myself, but I won't be selfish as this one came out so great!!! Ring size in 8 and the pattern I used for the ring is by Bobbi Maw with some small variations. The stone is wire wrapped onto a diamond cut patterned band.
