Lepidolite (Pink/Purple) with Rubellite Tourmaline
Lepidolite var. Mica with Schorl-Elbaite series var. Rubellite · Semi-Precious Gemstone / Mineral Specimen
Crystal System
Monoclinic (Lepidolite) and Trigonal (Tourmaline); usually appears in massive, micaceous, or columnar habits.
Mineral Group
Silicates (Phyllosilicates for Lepidolite; Cyclosilicates for Tourmaline)
Chemical Formula
K(Li,Al)3(Al,Si,Rb)4O10(F,OH)2 [Lepidolite] with Na(Li,Al)3Al6(BO3)3Si6O18(OH)4 [Rubellite]
Formation Process
Igneous/Pegmatitic; forms during the late stages of magmatic crystallization where lithium and boron are concentrated.
About This Crystal
A polished, triangular-shaped stone displaying a deep burgundy to purplish-red base with lighter pink, fibrous or linear inclusions. The luster is vitreous to pearly, and the stone is opaque to translucent on the edges.
Physical Characteristics
Color: Deep red to pink; Streak: White; Cleavage: Perfect basal (Lepidolite) / None (Tourmaline); Fracture: Uneven/Splintery; Specific Gravity: 2.8–3.2; Fluorescence: Sometimes pink/cream under LWUV.
Optical Properties
Refractive Index: 1.52-1.66; Birefringence: Weak to moderate; Pleochroism: Often strong in the red tourmaline sections; Doubly refractive.
Hardness & Durability
Origin Region
Brazil (Minas Gerais), Madagascar, and USA (California/Maine); typically found in lithium-rich granitic pegmatites.
Hardness & Durability
Variable: Lepidolite is soft (2.5–3.5 Mohs), while Tourmaline is hard (7.0–7.5 Mohs). The matrix is fragile due to micaceous cleavage lanes.
Care & Maintenance
Avoid ultrasonic cleaners and steam. Clean with warm soapy water and a soft cloth. Store separately to avoid scratching the softer Lepidolite components.
Rarity & Value
Relatively common; value is determined by the size and intensity of the red Rubellite inclusions and the quality of the polish.
Special Characteristics
Exhibits a 'scrambled' or 'leopard' pattern due to the intergrowth of lithium-rich mica and tourmaline crystals; often shows a shimmer/chatoyancy in the fibrous sections.
Lore & History
Historically associated with peace and lithium-based balance. In lore, Lepidolite is known as the 'Stone of Transition' or 'peace stone,' often linked to the Heart and Third Eye chakras.
Notes
Deep red and light pink
