జ్యోతిషంలో పసుపు నీలం (పుఖ్రజ్): గురు రాయి — గురు కృపా రాయి

Pukhraj as Guru Ratna — Classical Authority from Brihat Samhita and Garuda Purana

Pukhraj (Yellow Sapphire), known in Sanskrit as Pushparaga or Guru-mani, is the premier ratna of Brihaspati (Guru, Jupiter) in Vedic Jyotish — the graha of dhrama, vidya, santana (progeny), vivah (marriage for women), guru-parampara, and divine grace. The Brihat Samhita of Varahamihira and the Agni Purana both praise Pushparaga for removing paapa (karmic obstructions) and conferring Guru's blessings upon the wearer. A Jyotish-grade Pukhraj must display a canary-to-golden yellow colour of even saturation without secondary green or orange tints, high clarity with minimal eye-visible inclusions, and strong transparency allowing light to pass freely through the crystal. Among origins, Ceylon (Sri Lanka) Pukhraj is considered the gold standard — its cornflower-yellow to golden-yellow hue with characteristic Jyotish lustre is preferred by most classical practitioners. Thai, Australian, and African yellow sapphires exist commercially but are considered inferior in Jyotish reckoning due to colour differences. A minimum of three rattis is traditional, with five to seven rattis often prescribed for Guru Mahadasha. No beryllium heat treatment — widely used to induce yellow colour in geuda sapphires — is acceptable; treated specimens fundamentally alter the gem's crystalline information and are considered inert for Jyotish purposes. Always request a GIA or GRS report confirming 'No indication of heating.'
