Gem rough was sourced in Madagascar and cut in Sri Lanka. This gemstone is a 5.2x4.3mm cushion and weighs .615 cts. This stone is fully natural - NOT synthetic! This stone has a bright color-change - purple in indoor lighting and almost teal green in outdoor lighting (daylight). There is a tiny inclusion - a small "feather" or internal crack at the bottom of the stone. In the right mounting, that will not be noticed, but the color and color-change will be.
I have a co-op partnership with the Sri Lankan vendor. So every sale of their gems helps TWO small businesses! This could be kept as part of a gem collection, or mounted into any piece of jewelry you desire.
