Received an IF stone!

Holy moly! We purchased the ~2.7ct size and received a 2.85ct E IF stone. Did not even think it was possible to go above VVS. Unbeatable for the pricing.

Amazing stone at an amazing price!

We've been looking at replacing the stone for my CZ engagement ring for a few months now and the pricing here was unbeatable for a D color VS1 diamond!!! Everyone else was offering a G/H color SI+ stone for the same pricing if not MORE!!!

The stone itself is incredible and is an absolute beauty under natural light. I never thought I would be able to tell the difference between CZ and diamond, but after holding a real diamond on my hand now there is just so much more depth to a diamond than I ever realized. Thank you Liz and Gema for my beautiful stone!
