Our Jewelry

As a jeweler who is tied into the wholesale diamond business in NYC’s diamond district, all of the diamonds that we carry in stock have been hand selected from our vast wholesale inventory by our in house GIA Certified diamond graduate. We believe the most brilliant loose diamonds make the most gorgeous engagement rings.

We only sell natural certified diamonds that have not been enhanced for color or clarity. All of our certified diamonds have gone through the extensive certification process by either GIA or EGL USA labs, they are conflict free diamonds, and also accompanied by an insurance appraisal.
