Gemstone Ratti Weight Guide: How Much to Wear Based on Body Weight
Quick Answer: How Do I Calculate the Correct Ratti Weight for My Gemstone? The standard formula in contemporary Vedic gemology is: Body weight (kg) ÷ 12 = Minimum ratti. So a person weighing 60 kg should wear at least 5 ratti (60 ÷ 12 = 5). Some astrologers use the simpler ÷10 rule (60 kg → 6 ratti), which is also in practice. Regardless of formula, 4–8 ratti covers most adults comfortably, and 12 ratti is the widely observed upper ceiling. A smaller, high-quality, unheated natural stone always outperforms a large but treated or flawed one.
रत्नों में रत्ती का क्या अर्थ है? रत्ती भारत की परंपरागत वजन इकाई है जो गुंजा बीज (Abrus precatorius) के बीज के वजन पर आधारित है। 1 रत्ती ≈ 182 mg या ≈ 0.91 कैरेट। आपका सही रत्ती जानने के लिए: अपना वजन (kg) में 12 से भाग करें। उदाहरण: 72 kg ÷ 12 = 6 रत्ती।
Anyone who has visited a Vedic astrologer has almost certainly been told to wear a gemstone of a specific “ratti.” The number can feel arbitrary - why 5 ratti and not 4? Why does body weight matter? And what happens if you can't find that exact weight? This practical guide answers every variation of that question, covering the standard calculation formula, stone-by-stone minimums, the critical quality-vs-weight principle, and the classical textual basis for gemstone weight recommendations.
Whether you are looking at a Ruby (Manik), Yellow Sapphire (Pukhraj), Blue Sapphire (Neelam), or any other Navaratna, the principles here will help you make an informed, confident decision - and avoid the common mistake of prioritising a heavier stone over a better one.
