Look at this amazing sapphire! It has the superior luster that you would expect from a high end sapphire, but it also features a very unique color palette. Very unique. It starts with a clear crystal body color with just a touch of blue in its undertone, but look at the video and you'll notice darker blue. Look closer, and you'll see that the darker blue color comes from striations in the gem! It gets its color from iron and titanium, the minerals that give sapphires their blue color. But unlike regular sapphires, these minerals didn't saturate the entire crystal. Instead, they wove their way through it, creating not only one of the most bespoke natural sapphires you've ever seen, but also a fantastic geological find. All captured under a premium polished luster that gleams across the entire gemstone. And you can wear it! The size of this piece makes it perfect for setting at 12mm x 4.5mm x 3.8mm, and with its distinct appearance and impressive coloring, it will stand out whether it is set on its own, incorporated with other other gems, or simply adding a high note to your collection.
