What to Consider When Choosing Weight

Make informed decisions based on these key factors

  • Astrological Recommendation

    Always consult an astrologer for the ideal weight based on your birth chart. Typically recommended in Ratti.

  • Body Weight Calculation

    General rule: 1/10th to 1/12th of your body weight in kg equals recommended gemstone weight in Ratti.

  • Visual Appearance

    Consider how the gemstone will look on your finger or neck. Larger stones make bolder statements.

  • Budget Considerations

    Gemstone prices increase exponentially with carat weight. Balance quality and size within your budget.

Common Mistakes to Avoid

Protect yourself from these frequent purchasing errors

  • Confusing Carat with Karat

    Carat measures gemstone weight, while karat measures gold purity. Don't mix them up!

  • Ignoring Density Differences

    Same carat weight looks different on different gemstones. A 5-carat sapphire is smaller than a 5-carat emerald.

  • Buying Without Certification

    Always ask for a certified lab report verifying the gemstone's weight and authenticity.

  • Focusing Only on Weight

    Quality matters more than size. A smaller, high-quality gemstone is more valuable than a larger, flawed one.

Historical Context

The Story Behind Gemstone Measurements

Origin of Carat

The word "carat" comes from the carob seed, which ancient traders used as counterweights on their balance scales. These seeds were remarkably uniform in weight, making them perfect for measuring precious gemstones. In 1907, the metric carat was internationally standardized at 200 milligrams.

Origin of Ratti

Ratti is a traditional Indian unit of measurement derived from the red and black seeds of the Gunja plant (Abrus precatorius). These seeds were historically used in India for weighing gold and gemstones. The measurement has been preserved in Vedic astrology, where gemstone recommendations are still given in Ratti.

Modern Usage

Today, while the international jewelry industry primarily uses carats, Ratti remains prevalent in India, especially for astrological gemstones. Understanding both measurements is essential for anyone interested in authentic gemstone astrology or purchasing gemstones from Indian sellers.

Why do astrologers recommend gemstones in ratti instead of carats?

Many Vedic astrologers recommend gemstone weight in ratti because it has been the traditional Indian unit of measurement for centuries. However, most certified gemstones are sold in carats. Converting between the two ensures you purchase a gemstone that matches your astrologer's recommended weight.

Is the weight of a gemstone important in astrology?

Yes, gemstone weight is considered an important factor in Vedic astrology. Astrologers often recommend a specific weight based on your birth chart, planetary positions, and desired astrological outcomes. Along with weight, the gemstone should also be natural, untreated, and certified for the best results.

Can I use the Carat to Ratti Calculator for all gemstones?

Yes. The Carat to Ratti Calculator can be used for most gemstones, including Yellow Sapphire, Blue Sapphire, Ruby, Emerald, Pearl, Red Coral, Hessonite, Cat's Eye, Diamond, and other precious or semi-precious gemstones. Since the calculator converts weight only, it works regardless of the gemstone type.

Should I buy a gemstone in carats or ratti?

The unit itself does not affect the gemstone's quality. Most jewellers sell gemstones in carats, while astrologers usually recommend them in ratti. The best approach is to convert the recommended weight accurately and purchase a natural, certified gemstone that closely matches the suggested weight. This ensures consistency between the astrological recommendation and the gemstone you receive.
