We have been looking at engagement rings for a few weeks now and have looked into moissanite (i love the pink ones!)...As we were looking around at Kay Jewelers, I asked the salesperson about moissanite. She said to not go that route because moissanite held little value and there was no telling how the stone would hold up in ten to thirty years because moissanite has not been on the market for that long. She also said that if I were to try to replace a moissanite stone to a bigger diamond stone in a few years, that it would be impossible because settings for moissanite are not designed for diamond or for larger stones, and i would have to get a completely new ring. I have a $900 budget for my e-ring, and don't want to spend so much money on something that might not have any value. So, is this all true? What are some cons of moissanite besides color?
