". . . a real diamond?" LOL! I have a 3.5 carat Moissanite on my left ring finger. . . surrounded by one carat of very good diamonds. . . and as I pointed out I have over 150 real diamonds. Look back at my comments. My girlfriend and I own quite a few real diamonds and also a lot of Moissanites. . . my girlfriend has a C&C 10 carat Moissanite in a solitaire ring mounted in a Skater's Waltz setting. I would bet we've been buying both types of stone for a lot longer than you, and in more quantity. I once bought fifty loose C&C Moissanites for a jewelry project I designed.
In case you might be wondering, here is what a 92 carat black diamond looks like (yes, that's my thumb and index finger in the photo). . . notice it has a flat table:
It's approximately 1 ⅛" in diameter. That ~250 carat one I was thinking of buying was only about 1 ⅓" in diameter. It's amazing what the square-cube law does to mass for just a tiny increase in size.
I've also bought Moissanites from manufacturers in India in various colors before C&C started offering colored Moissanite. The Indians couldn't make the colorless. . . but they could make almost any other color, including blue. They were the first to offer that color.
Try again to denigrate my knowledge of jewels another way.
