That's interesting - when I bought an engagement ring for my wife the one and only jewelry store I went to was happy to order me a bare ring, give me the size range of diamonds that would fit it, and then install the 3 synthetic diamonds I ordered from Gemesis. It seemed like installing diamonds that folks already owned into new rings was something they did relatively often. Maybe you'd have better luck approaching it that way - "I already have a diamond, what rings can you sell me that would fit it?" rather than "source me a synthetic diamond and put it in a ring for me". Although it looks like Gemesis, the company I bought the synthetic diamonds from, has pivoted and rebranded as Pure Grown Diamonds, and sells wholesale rather than retail now.
