I have no business connection with the Diamond Vault (other than as a customer), and am not related in any way to the management.
If you want to buy a diamond ring, earrings, bracelet, or just unset diamonds, this is pretty much the only place in town at which to do it. The owner is directly involved in the international diamond trade and he knows his stuff. But what is most important -- he is scrupulously honest. You will get a good value, as the Diamond Vault's markups are quite reasonable. The stones will be properly graded and expertly set. Promises will be kept.
The only downside is that it truly looks like a vault -- a small vault at that. This is not a place to browse through aisle after aisle of glittering creations -- it is a place to buy diamond jewelry.
Note: They do custom creations on site as well. I had a necklace made to my design. It came out exactly as I specified, but when my wife put it on, we had an issue with the way it hung. I took it back to be altered, and they again did what I said. No charge. It still wasn't perfect. I took it back again and once more they did just what I asked. It still wasn't perfect. I took it back a third time and they gently told me to just let them take care of it -- they knew what to do. They were right. There goes my career as a jewelry designer.
