I keep coming back to this website. Navigation is nearly perfect, they just need to add an option to select/unselect the 'treatment' of crystals. And I would like to be able to save all the photos of crystals I'm purchasing and not just the first one. This site is I believe is best out there for in depth variety of sizes and colors. I give it 10/10. If they don't have something I need and I have to shop somewhere else I keep coming back here just to compare prices vs clarity just so I can size up other crystals from somewhere else. This site sets standards!!
Gem Select makes it super easy to just find a particular stone that meets your requirements. They have a large taskbar with many different filters to really narrow down your search by cut, clarity, size, even color! I've never seen another site that has all those options.
The selection of gemstones is absolutely amazing! The pictures allow you to get important angles of each individual stone and, from what I see, there aren't any just standard photos used unless there are duplicates of very small stones- which is completely understandable. They tend to describe their reasoning too.
My only consideration for this particular purchase is that it is from a lot and I don't get to select the specific gem I want. However, I trust GemSelect and they all look good in the picture provided and are all the same approx. size and weight. My only real concern is the star in the star ruby, as I want one that is both clear and shapely.
