Natural Gemstones, Scientifically Certified.
Every gemstone available through Poornima Gems is natural, tested in our laboratory, and supplied with a certificate of authenticity. We do not sell synthetic stones, glass-filled imitations, or heavily treated stones without full disclosure.
Ruby
Ruby is one of the most revered gemstones in Vedic astrology, associated with the Sun and its qualities of vitality, authority, and clarity of purpose. In gemological terms, ruby is a red variety of corundum — the same mineral family as sapphire — and its rich colour comes from trace amounts of chromium.
Mineral
Corundum (Al₂O₃)
Colour
Red to deep blood-red
Hardness
9 Mohs — highly durable
Origins
Burma, Sri Lanka, Mozambique, Thailand
Wearing Guidance
Blue Sapphire
Blue Sapphire is widely regarded as the most powerful stone in Vedic astrology. Its influence can be felt quickly — sometimes within days of wearing — and for that reason, it must be approached with particular care and professional guidance. We always recommend a trial period before committing to wearing Blue Sapphire.
Mineral
Corundum (Al₂O₃)
Colour
Cornflower blue to deep velvety blue
Hardness
9 Mohs
Origins

Yellow Sapphire
Pukhraj
Yellow Sapphire is one of the most widely recommended and consistently beneficial stones in Vedic gemology. Associated with Jupiter — the planet of wisdom, abundance, and good fortune — it is among the safest stones to wear when Jupiter is favourable in your chart.
Who Should Wear
Yellow Sapphire is particularly recommended before significant life events — a marriage, a new business venture, an examination, a relocation. It is associated with clarity of judgement, prosperity, and auspicious timing.

Hessonite
Gomed
Hessonite garnet is associated with Rahu and is recommended during Rahu Mahadasha or for those with an afflicted Rahu in their horoscope. Ceylon Hessonite is the most prized variety. Often confused with spessartine garnet — certification is essential.
