Tourmaline with verdelite

Verdelite is a charming variety of the mineral tourmaline, distinguished by its rich palette of green shades, from delicate spring to deep, rich emerald tones. This valuable mineral is formed mainly in igneous (especially pegmatite) and metamorphic rocks. Due to its stability, verdelite crystals are also often found in river sediments. Its name, derived from the Italian "verde" (green) and the Greek "lithos" (stone), aptly reflects its bright color.

The main deposits of verdelite are located in Brazil, Afghanistan, Pakistan, the USA (California, Maine), as well as in African countries (Namibia, Nigeria, Mozambique). Verdelite is known for its unique optical properties. When cut as a cabochon, it can exhibit a "cat's eye" effect (chateau-yancy) - a silky strip of light iridescent on the surface caused by parallel micro-inclusions.

Verdelite is also characterized by strong pleochroism: the stone can change the shade of green (for example, from yellowish-green to bluish-green) depending on the angle of view. Due to its beauty, sufficient hardness (7-7.5 on the Mohs scale) and variety of shades, verdelite is highly valued in jewelry for the creation of rings, pendants, earrings and other ornaments. It is also revered by mineral collectors for the perfection of its crystal form and richness of color.

Transparent crystals of jewelry quality are especially desirable. Historically, verdelite was used in decoration, including in the Victorian era in mourning jewelry as a symbol of hope.

Today, verdelite remains a popular gemstone, attracting attention with its natural luster, cheerful green color, and interesting optical effects.
