Gemological overview

Technical and gemological information about this gemstone variety.

Gemological profile

Spodumene is a silicate mineral known for its elongated crystal habit, high transparency, and refined internal structure. In gem-quality material, spodumene is valued for its clean appearance and ability to display subtle to vivid coloration depending on the specific variety.
Chemically composed of lithium aluminum silicate (LiAl(SiO₃)₂), spodumene crystallizes in the monoclinic crystal system and belongs to the silicate mineral group. Transparent gem-quality specimens typically display a vitreous luster and high clarity.
The refractive index of spodumene generally ranges from approximately 1.66 to 1.68, resulting in a lively brilliance with noticeable light return. Spodumene is found in several regions worldwide, with notable sources including Afghanistan, Pakistan, Brazil, Madagascar, and the United States, depending on variety and geological conditions.

Durability & suitability

With a hardness of 6.5 to 7 on the Mohs scale, spodumene offers moderate durability suitable for jewelry when properly set and worn with care. While it can be used in a range of jewelry designs, it performs best in pieces that are less exposed to frequent impact, such as pendants, earrings, and protected ring settings.
Spodumene has perfect cleavage, making thoughtful setting design especially important to reduce the risk of damage from sharp impact. Its combination of clarity, size availability, and elegant appearance makes it particularly suitable for occasional-wear jewelry and expressive, statement-oriented designs.

Treatments & authenticity

Spodumene is commonly heat treated to enhance or stabilize color in certain varieties, a practice widely accepted within the gem trade when properly disclosed. This treatment is stable and does not compromise the structural integrity of the gemstone.
Any treatments or enhancements are always clearly stated for each individual gemstone. Every stone is professionally examined, and transparent disclosure is regarded as a fundamental part of responsible gemological practice, allowing clients to make informed and confident decisions.

Our approach to gemstones
