A diamond takes a billion odd years to form. So it’s understandable that innovations involving the gemstones don’t roll around too often. That’s probably why the “floating diamonds” trend so widened our eyes. As imagined by Royal Assher, a diamond house since 1854 whose rings and necklaces are on display at Aspen’s Caribou Jewels, the pieces feature a fluid-filled sapphire dome with loose diamonds floating inside. The collection’s name—Stars of Africa—refers to the fact that $150 from the sale of each piece funds educational, health, microeconomic, or self-sufficiency philanthropy on that continent. The pieces’ aesthetic effect? Simply spellbinding.
