Good news: trillion moissanites are being made by Charles and Colvard again and are now available as the near-colorless (GHI Color) and colorless Forever One moissanites (DEF Color). I added all available size options to my trillion moissanite ring designs and even the bezel stud earrings.
I still have a few of the Forever Classic moissanites (J-K color) left in sizes 5mm/0.36ct and 5.5mm/0.55ct and one Forever Brilliant moissanite (GHI Color) in 7.5mm/1.35ct. Those have been reduced in price to help close them out. They still have the same fire and brilliance we all love in moissanites.
