Diamond — also known as Heera, Vajra, Heerak, or Shukra Ratna — is the most powerful gemstone for Venus (Shukra) in Vedic Jyotish. It is pure crystallized carbon — Earth's hardest naturally occurring material (Mohs 10). In India, the price ranges from ₹15,000 to ₹5,00,000+ per carat — depending on the 4C factors (Cut, Color, Clarity, Carat).
In Vedic Jyotish, Venus governs luxury, love, beauty, arts, marriage, and material wealth. Natural IGI/GIA certified diamond is considered effective for Jyotish — Lab Grown is not.
Rules luxury, love, beauty, arts, and material success. Diamond channels Venus's cosmic energy.
