When Diamond has a Star Asterism

Have you ever seen a diamond that seems to hold a secret light inside, almost like a tiny star frozen within the stone? As light touches its surface, a gentle star like pattern appears, glowing from within and drawing your eyes closer. It feels less like a diamond and more like nature’s own signature, a quiet celestial moment captured in crystal.
We’re excited to introduce two extraordinary rough octahedron diamonds that carry this celestial phenomenon. One weighs 4.06 cts (9.9 × 9.6 × 9.3 mm) and the other is 8.38 cts. Both are natural rough diamonds in their original octahedral shape untouched, uncut, and exactly as nature formed them. These aren’t polished for sparkle yet… because their beauty already lives inside.
What is an Asteriated Diamond?
These are asteriated diamonds rare rough diamonds that display a natural star effect. This fascinating effect is called asterism. The word comes from “aster,” meaning star, and it describes the glowing star-like pattern that appears when light interacts with specific internal growth structures inside the diamond. As the crystal formed millions of years ago under extreme heat and pressure, microscopic inclusions and aligned mineral channels developed naturally. When light reflects along these aligned structures, it creates the soft star effect you see. It’s a purely natural event, something that happens only under very precise conditions deep inside the earth.
Because these conditions are so specific, asteriated diamonds are incredibly rare. Even among thousands of rough diamonds, only a few ever show this phenomenon clearly. Most diamonds will never develop this internal alignment, and many lose such features during cutting. That’s why finding a rough diamond that still displays a visible star pattern in its natural form is special. Each one is truly one of a kind, with a pattern that can never be copied or recreated.

Collector’s Piece or Jewelry Creation?
For collectors, these diamonds are treasured for exactly that reason. They represent nature in its purest state untouched, original, and geologically fascinating. Owning one feels like holding a piece of the earth’s history, something formed long before human hands ever discovered it. For designers and jewelers, these diamonds offer exciting creative possibilities. Their octahedral shape and organic character make them perfect for raw crystal pendants, statement rings, talisman-style pieces, or bold contemporary jewelry. Instead of traditional sparkle, they offer depth, story, and personality jewelry that feels meaningful and rare.
Our Experience with Asteriated Diamonds
Sourcing true asteriated diamonds takes time and expertise. We’ve been working with these rare natural diamonds for years, and in most cases, we find only a few genuine pieces each year sometimes even less. Not every rough octahedron that glows qualifies as an asteriated diamond, even though many are marketed that way. The real star effect requires very specific internal structures, and knowing how to identify that comes from experience.
Over time, we’ve carefully curated exceptional pieces for collectors and designers, helping transform them into meaningful, one of a kind jewelry. These two diamonds rank among the finest we’ve sourced selected with a trained eye, trusted knowledge, and a deep understanding of what true quality looks like.
