This chrysocolla stone carries one of the most striking color ranges in the gem world, deep teal, turquoise-blue, and green sitting side by side in the same piece, sometimes shifting within a single cabochon.
As a chrysocolla gemstone, it forms in the oxidized zones of copper deposits, which is exactly why copper's signature blue-green shows up so vividly, copper is the coloring agent behind both chrysocolla and better-known stones like turquoise and malachite.
What makes this chrysocolla crystal genuinely tricky to source cleanly is that it rarely forms alone.
Most commercial material shows up intergrown with other copper minerals, chrysocolla in malachite is one of the most common pairings, dark green malachite streaking through the blue-green base in the same rock.
This lot leans toward the cooler, more saturated end of the spectrum, closer to blue chrysocolla, which tends to command more attention than the softer green variety since the color reads as more vivid and "electric" at a glance.
Each cabochon here is cut to a calibrated radiant shape, sourced from Congo, matched in size for coordinated jewelry work rather than sold as a random mixed lot.
Because chrysocolla is on the softer side for a gemstone, it's generally set with care, in pendants and earrings especially, where the color can be the whole design.
