I regularly laser machine industrial cemented diamond blanks into high-pressure fluidic cells. My wife often jokes about the fact that I cut up diamonds at work and people are always intrigued by the idea of a black diamond.
The above diamond was improperly ground and was therefore useless except for laser testing and practice. So when I decided to make my wife a piece of jewelry for her birthday/graduation gift, I knew exactly what to make it from.
Prompted by a tattoo discussion from months prior, I knew that the necklace must incorporate a dot for her mother and a square root of 25 for her dad. Everyone calls Dorothy “Dottie” and Wayne trained his kids to know the square root of 25 and a few other odd facts as a way to prove his kids were smart when they were little.
For the finished piece, I used the laser to cut pearl guitar inlays to fit the lasered recesses that I cut in the diamond. I then epoxied the fragile little parts into the cavities and polished the faces when the part was fully cured. I also had to laser drill a hole into the side for the small modified bolt that would hold the diamond pendant to a modified, Amazon purchased, silver necklace. The little bolt and necklace hole allow the pendant to rotate so both sides can be seen.
