About Black Sunstone
Mysterious, Metallic & Under Investigation
Black Sunstone is a striking new lapidary material out of southern India that’s turning heads—and raising questions. Despite its trade name, it’s not a sunstone in the traditional sense. There’s no feldspar, no schiller, and no clear consensus on what it actually is—only that it’s magnetic in every sense of the word.
Some sources are calling it a graphite-bearing grey aventurine. Others claim it’s a form of quartz. Here’s the rub: it can’t be both. Aventurine is a variety of quartz, sure—but graphite isn’t a typical inclusion for aventurescence, and if it were dominant, you’d expect a dull, waxy sheen—not the glittering, metallic sparkle this material shows off in every cabochon.
What we do know:
-
It’s dark—ranging from gunmetal grey to deep black.
-
It sparkles—seriously, it lights up under the right light.
-
It takes a mirror-bright polish that lapidaries love.
-
It has an energy that feels ancient, elemental, and a little untamed.
Until someone puts this mystery rock under a microscope and gives us definitive lab data, we’re leaning into the intrigue. It’s bold. It’s beautiful. And it’s begging to be explored.
