It's very interesting that he was able to do it at all. I went to three different Jewelers and all told me that they are not able to recreate this design because they would need to purchase diamonds with an incision kind of midway along the height, which is where the setting holds the stone. The jeweler could not purchase these diamonds because such diamonds could be only purchased in bulk and were only sold by two or three suppliers around the world. This makes a lot of sense because I couldn't understand why no copycats emerged with similar invisible set diamonds designs.
Likewise, I’ve been trying to find more affordable options for Maria’s diamonds. I finally had a 5.5 mm moissanite I had set in a threadless end style but the most minimal setting was a three-prong martini, and it still sits so high in the basket it looked weird in my third lobe hole (where I wanted it). So for now I have it in my first hole where it sits facing more forward, and then Jack & G baby chimes and Birks hoops.
I did find this vendor on Etsy (second pic below) that has an “invisible” setting using either moissanite or lab diamonds, but the basket still is quite big.
