Since I'm looking at my options for a ring with interchangeable stones, I'm wondering right now why cubic zirconia seem to have a reputation as not- so -good right, though they look nice, have decent hardness (8.5 on the Mohs scale) and come in a wide variety of colors.
Is it just because it's a very plentiful and therefore inexpensive material? Or is there more to it than that? Maybe because it's a synthetic material?
Also, are CZs "cut" like other lab created stones or just poured into a mold? (I can't imagine anyone taking the time to cut all those tiny facets for a stone that costs next to nothing).
