Spectrolite cabochon from Finland.
High-grade spectrolite from Finland with vivid multicolor labradorescence—rich blues, greens, and golds across a dark base. Spectrolite is a rare variety of labradorite, a calcium-rich plagioclase feldspar. Its vibrant color play is caused by light interference within microscopic lamellar structures in the crystal. Discovered in the 1940s and found only in southeastern Finland, spectrolite is sought after for both its rarity and its exceptional optical qualities
