description Overview

Cobalt Spinel

Cobalt spinel is a rare blue variety of the mineral spinel, colored by trace amounts of cobalt. Unlike typical grayish-blue spinels colored by iron, cobalt spinel exhibits a vivid, pure blue hue. Significant deposits are found in Vietnam and Tanzania. It is frequently used in fine jewelry and is favored by gem collectors for its durability and brilliance.

Serendibite

Serendibite is a borosilicate gemstone primarily found in Sri Lanka. Its notable characteristic is an intense dark blue color, often with cyan hues, making it exceptionally rare among minerals. The stone’s scarcity and unique appearance make it desirable for collectors and jewelers creating distinctive jewelry pieces. It's particularly valued by those seeking unusual gemstones.
