Evelyn Stones: A Comprehensive Guide

Introduction

Evelyn stones, also known as evelynites, are unique and captivating minerals that have captivated the imagination of geologists and collectors alike. Named after the late Evelyn Langston, who first discovered them in 1955, these stones have gained prominence for their mesmerizing appearance and intriguing geological properties.

Characteristics of Evelyn Stones

Evelyn stones are characterized by their distinctive:

• Crystalline Structure: Composed of elongated, needle-like crystals called actinolite.
• Coloration: Typically range from deep green to olive green, but can also exhibit shades of brown, black, and orange.
• Optical Properties: Exhibit a distinctive chatoyancy, or "cat's eye" effect, when cut and polished.
• Hardness: Rank 5.5-6 on the Mohs scale, making them relatively durable.

Formation and Occurrence

Evelyn stones form during the metamorphism of impure magnesium-rich limestone. The intense heat and pressure within the Earth's crust cause the limestone to recrystallize, resulting in the growth of actinolite crystals that give the stones their characteristic appearance.

Evelyn stones are primarily found in metamorphic rocks such as schist and quartzite. Significant deposits have been discovered in:

• Western United States: California, Nevada, and Montana
• South Africa: Barberton Greenstone Belt
• Italy: Valmalenco district
• India: Tamil Nadu state

Uses

Evelyn stones are primarily used as decorative materials. Their striking color and chatoyancy make them popular for:

• Jewelry: Cabochons, beads, and other jewelry pieces
• Carvings: Small sculptures, figurines, and other decorative objects
• Architectural Elements: Fireplace surrounds, countertops, and other architectural accents

Economic Value

Evelyn stones command a relatively high value in the mineral market. The rarity of true evelynites and the demand for their unique properties have contributed to their economic significance.

• Average Price Range: $20-$80 per carat for polished cabochons
