Purchased: GIGAJEWE Moissanite Handmade Heart Cut Radiant Sun Color VVS1 Premium Gems Loose Diamond Test Passed Gemstone For Jewelry Making

“The stones are absolutely beautiful. As a novice, I wasn't sure about size. Both sizes were beautiful and I wasn't aware the color differences between sizes. Doesn't really matter. They were so beautiful, I ordered some rounds. I can't wait to see them in the Florida sunshine. They have not been mounted yet, but I will add a pic when I have.”
