This is a nice piece; however, I returned it. I purchased two different green amethyst heart necklaces from Overstock and compared the two. One in white gold and the other in yellow gold. I realize white gold tends to be a bit pricier, but I'm more concerned about how the piece looks overall. Both stones have nice clarity. This pendant is 10mm and 3.5 carats. The other is 12mm and 7.5 carats. In my hand, the 7.5 carat felt a bit more substantial and the color of the larger stone was deeper. I do think the white gold is a nice design, but the heavier white gold setting and tiny diamonds almost take away from the piece. Maybe 3.5 carats of green amethyst isn't enough material to build the nice green color. It wasn't as spectacular as I expected. I was surprised because I liked the less expensive yellow gold pendant with the simple design more. The stone is nicer. I love that Overstock makes comparison shopping a breeze and returns are so simple. I'm keeping the yellow gold one; It has a simple design that doesn't detract and the stone is more stunning.
