Stones listed with a six digit SKU are ones we have in stock. The other stones are either readily available in a range of cuts and sizes, or can be custom cut.
For colored stones, we primarily work with sapphires or diamonds—because of their hardness, they are great for everyday wear. More information on gemstone wearability can be found here.
Colors may appear different on different monitors. Additionally, colored gemstones can change color depending on the light source. Natural sapphires have been heat-treated (unless stated as unheated), but do not have other treatments.
