Looking to purchase a round diamond to fit a Niessing tension setting. Would ideally like something 0.6-0.7ct, near to ideal cut, D-G, VS2-1. Have checked prices on BN, but could use your help in sourcing the best diamond at the best value. What other online sellers should I be checking for value, great diamonds, and honesty? Would like to stay around $2200 if possible. If anyone has specific diamonds in mind, please post. Thanks!!!
