by Dancing Fire » Apr 12, 2019 I received an Email from Wink stating that HPD are lowering all their prices on CBI stones, so I decided to take an advantage of the lowered price. My old H VS1 2.35ct was 8.55mm vs this new 2.60ct 8.85mm stone. I gained .30mm in diameter. The new stone is mounted on the same style Boone tension setting as my old stone. Bruce was nice enough to offer me a good discount on this new setting . Here's some pics of this new ring.
