They created a ring by incorporating my engagement diamond and 64 brilliant cut diamonds into a contemporary knock out ring for my 50th wedding anniversary!

Absolutely! Justin combined two rings I had. One was my mother’s ring, but there was always “something” I didn’t like about it. Justin picked up on exactly what that was in seconds! (And fixed it). It turned out beautifully, too. Koops have made both of my daughters-in-law’s engagement rings and both are so beautiful and one of a kind! I love grab-a-gem, too! Going to have some of the gems made into simple necklaces for gifts.

I have been using them for 16+ years starting with my wedding ring, and I recommend them to everyone. Justin and team have the best design, product and workmanship I have ever seen and the prices are reasonable.

Being obsessed with gems and minerals from before I could read, I was completely mesmerized...and so sad that from that moment till now it never saw the light of day. Yes, it's monstrous so this sentimental project took architectural ingenuity. Justin mastered the piece honouring the stone, my style, and intent to wear often. It was so much fun interacting with Justin and the end result is perfection. I'm so glad I was referred t... read more

I recently cosigned a large piece of jewelry with Koop. Justin was very knowledgeable about the value of the item and market pricing. Justin is fantastic to work with and the piece I consigned sold quickly! I highly recommend Koop for cosigning jewelry or any jewelry needs you may have. Justin's professionalism and customer service is next to none!! They are a five star business all the way!!
