  • Definitely professional in his sector, Justin helped me realise the piece I was looking for from scratch. Conversations were smooth and timely and even though we went through some little issues with the shipping he took care of it and made sure I’d receive the parcel.

  • We were looking for a padparadscha sapphire for an engagement ring and had a wonderful experience working with Justin. He was knowledgeable, fair, and was always on the lookout for a sapphire that would suit our needs. We would highly recommend him!

  • Loved the alexandrite ring I got from the rare gem. It looked even better in person than on the website. I had a lot of difficulty finding a jeweler that had alexandrite and I was very happy with the selection that Justin had.

  • Excellent service! Exceptional collection of stones! I was looking for a Padparadscha sapphire for an engagement ring, found The Rare Gem on Facebook, and went to their booth at Tucson. Justin helped me find the right stone. Maybe an alexandrite next time!

Red Diamond and Blue Diamond

Time and time again the notion of diamonds being rare has been displaced. There are exceptions to everything. Red diamonds and blue diamonds are amongst the most highly sought collectors items in the world. Their scarcity is unmatched. Most recently, a 12.11 carat fancy intense blue diamond sold for approximately $1.3 Million Per Carat! Sotheby’s Auction House estimates this 1.38 ct Red Diamond to sell for $1.8 to $2.8M USD!
