I recently received a few colored green moissanites to choose from for a custom order request. I have light green and dark green moissanites available in sizes: 5mm/~0.40ct (~0.5ct diamond equivalent) or 5.5 mm/~0.55ct (~0.6ct diamond equivalent). Moissanites come with a Warranty and Certificate of Authenticity from Charles & Colvard.
These moissanites come in a range of green shades from light green to dark green. They are beautiful intense colors. C&C stopped producing green moissanites a couple years ago and there is only a very limited amount of these stones still available. I just got a few round green moissanites in for 2 of my engagement ring designs: my Fold design and my Half Bezel Solitair Ring. The light green 5.5mm stone already sold. But the others are still available for now.
