Roberta is very nice to work with. I just bought an old mine cut diamond from her. I hope to send it to Singlestone to be re-polished but the transaction between us was most pleasant. Shipping was lightning fast, communication excellent and prices very reasonable.
Awww...I had to send it back. The chips in the diamond were going to be too expensive to fix when you took in to account the setting would need work too. Also one of the chips could be a was hard to tell. It would have come to about $900 for a diamond under 6mm and a setting under 2 grams with the risk that the diamond could be a total loss. But she was very nice and refunded me in full.
