Unheated Natural Ruby (Manik) Stones

Explore our rare unheated natural ruby (manik) stones — untreated gems that retain their colour and clarity entirely from nature, with no heat enhancement. Sourced from Burma (Myanmar) and Mozambique and fully lab-certified, these are the most sought-after manik stones for both serious collectors and Vedic astrology. An unheated ruby, the gemstone of the Sun, is considered especially powerful and pure for astrological use. Each certified natural ruby is graded for saturation, transparency and cut, and ships insured worldwide from Bangkok, Thailand.
