Cat's Eye Chrysoberyl
Identify with AppWhat Is Cat's Eye Chrysoberyl?
Cat's Eye Chrysoberyl is the chatoyant variety of chrysoberyl, valued for the sharp band of light that appears to glide across its surface. In the hand, a good specimen reads as greenish-yellow to brown, translucent, and bright, with vitreous to silky luster. Its identity is tied to that moving “eye,” not just its color.
Mineralogically, it is an oxide with the formula BeAl2O4, an orthorhombic crystal system, white streak, conchoidal fracture, and a Mohs hardness of 8.5. That hardness gives it excellent scratch resistance and makes it a very durable gemstone under normal conditions, though it should still be protected from harsh chemicals and extreme temperature changes.
Origin & History
The name chrysoberyl comes from Greek words meaning “gold” and “beryl,” a fitting root for material that often shows yellow, greenish-yellow, or brown tones. Cat's Eye Chrysoberyl was first described in 1800, and its collector appeal has remained centered on chatoyancy: the crisp, narrow band of light that moves when the stone is turned.
For a buyer or field collector, origin history matters because locality names can affect how a specimen is described and compared. Brazil, Sri Lanka, and India are the listed producing countries, with Minas Gerais, Ratnapura, and Madhya Pradesh noted as localities; collectors commonly verify mineral and locality records through mindat.org.
Where Is Cat's Eye Chrysoberyl Found?
Cat's Eye Chrysoberyl is found in Brazil, Sri Lanka, and India, and it is most commonly associated with Brazil and Sri Lanka. Notable listed localities include Minas Gerais in Brazil, Ratnapura in Sri Lanka, and Madhya Pradesh in India. When labeling a specimen, those locality names should be kept separate from the gem variety name.
Formation
Cat's Eye Chrysoberyl forms in metamorphic rocks and pegmatites, often in granite formations. Its chatoyancy is the feature collectors look for after the mineral is cut or viewed under a direct light source: the surface shows a concentrated band that shifts as the angle changes.
The mineral is chemically an oxide, BeAl2O4, with beryllium, aluminum, and oxygen as listed elements, and iron and titanium noted as common impurities. Its density of 3.7–3.8 g/cm3 gives the material a substantial feel for its size, while its non-magnetic response, white streak, and conchoidal fracture help place it within a careful identification workflow.
How to Identify Cat's Eye Chrysoberyl
Identify Cat's Eye Chrysoberyl first by its chatoyant band: a distinct streak of light that moves across the surface as the specimen is turned. Typical colors range from greenish-yellow to brown, and the luster can appear vitreous to silky. The effect should be active in light, not just a static pale stripe.
Confirming the material means checking its supporting properties. Cat's Eye Chrysoberyl is very hard at Mohs 8.5, translucent, non-magnetic, and has a white streak. It belongs to the orthorhombic crystal system, has refractive index values of 1.74–1.75, no listed pleochroism, no listed birefringence, and biaxial optical character.
