7901-50mm is a “Puff Heart” and is exceptionally popular because well, just look at the facets! Great brilliance as well. FYI, ICE has a lot of different hearts and they all sell well. This one sells really well.
7201-40mm facetted disk has been a top 5 seller for over 20 years. It has what seems like an infinite number of facets and it seems to have a hole in the middle but it doesn’t. A beauty by itself or incorporate it into your own design.
