Deep, but not dark. Filled with dancing light. Like the velvet of a desert night sky far, far from city lights, pulsing with billions of stars and planets. The cushion-cut of this stately blue spinel sends flashes of fire from the depths of the gem. The color is elegantly understated but hypnotizing. Unlike many other blue gemstones including sapphire, tanzanite, and aquamarine, blue spinels are never treated to enhance their color. That means that this penetrating deep blue shade is exactly as it was created thousands of miles beneath the earth's surface, over the course of millions of years.
