Good morning! Wanted to share that I have just gotten this engagement ring back from the jeweler. It's a 1.41 ct natural Ceylon white sapphire, untreated. Platinum setting, very small aquamarine under the center stone (my birthstone is Sapphire and hers is aquamarine,which is why I designed it that way). I love how the color changes depending on the lighting. I'm REALLY happy with how it turned out. Now she just has to say yes . For reference, the hand pics are my hand, and the ring is a size 6 which fits pretty well on my middle finger.
