We buy all types of diamond jewelry: rings, earrings, necklaces, pendants and bracelets.

We will make an offer for the whole jewelry piece: valuing the diamonds, the other gemstones (sapphires, rubies, emeralds, etc.) and the metal.

Expert valuation 

All of our laboratory technicians are highly-trained gemologists with experience from working for and/or teaching at the most prestigious grading laboratories in the world.

Safe, fast and easy process

Your jewelry will be insured and shipped at no cost to you. Our services are free of charge and you can change your mind at any time (up until you accept payment).

By un-mounting the diamonds and applying industry-leading technologies to the valuation process, we can help you to receive the most attractive price for your diamond jewelry. 

But don’t take our word for it – let us prove it to you. We strongly encourage you to seek offers from other companies before coming to us.
