Beryl var. Heliodor w. Schorl Tourmaline Crystals - Height: 40 mm - Width: 30 mm- 143 g - (4)

Heliodor is a golden to yellow variety of the mineral beryl, prized for its clarity and warm hues that resemble sunlight. Often used in fine jewelry, heliodor shares its mineral family with emerald and aquamarine but is distinguished by its vibrant yellow coloration, which arises from trace amounts of iron in its structure. When found in association with schorl tourmaline crystals—black, prismatic forms of tourmaline—such mineral specimens highlight contrasting colors and crystal habits, making these samples highly prized among collectors. Tourmaline itself is a complex boron silicate mineral recognized for its wide color range and intriguing physical properties, including piezoelectricity. The combination of heliodor and schorl in a single specimen creates a visually appealing and scientifically interesting example of mineral co-crystallization. These specimens typically form in pegmatite deposits, where slow cooling allows large and well-formed crystals to develop. Collectors value such mineral pairs for display and study, appreciating both aesthetic qualities and geological context.
