Best way to buy two best cut side diamonds

[eiger]

I’m looking to buy two matched .55 -.6 diamonds Vs-Si quality with color around g to create a three stone ring with my transitional cut diamond. I want the best sparkle possible and I’m happy to buy used. A pair of earrings would be great. Used HOF diamonds sell at a premium. What else can 8 look for aside from Gia triple x, which might not be as well cut as I would like?

You're trying to put well-cut modern round brilliants next to a transitional cut? I've never seen that done before.

Have you spoken with whoever you are planning to use to set them?
