Pretty and striking!
The stone is delicately placed in a hand-cut top bezel frame, while the twisted silver and raindrops create a setting. I love this paired silver handiwork around the stone because it helps the colorful Blue Diamond Turquoise to stand out.

Mined for only a short span of time in the '60s and '70s, the classic Blue Diamond stone was a very small deposit – considered a ‘hat' mine – because you could cover the findings with your hat. The stone was mostly recovered in slabs, and are recognized by darker blue colors and strong black matrix, sometimes as smoky swirls, and usually with black chert. This mine is now closed and buried under rock.
