What is Ratti - Understanding Ratti in Astrological Gemstone

Ratti, derived from Sanskrit Raktika, holds its significance in the Indian metrics systems as the oldest form of unit measurement.

In a more simplified way, we can say Ratti is an Indian traditional and common way to determine the weight of a gemstone. 

However, no one could tell so far as who brought up the concept of Ratti in the Indian sub-continent.

Some think that it rose to fame during the period of royal advisor Kautilya, while others say Ratti was introduced by the Mughal Empire.

What is Ratti

Originally, Ratti is a native plant to India, with Gunja seeds whose size and weight remain the same.

The seeds were further used for weighing gold and silver by many jewellers in earlier days.

This was done because of a need for measuring tools in those times. Although this practice is rare now, it is still performed on a small scale. 

1 Ratti is = 180 milligrams

According to the jeweller’s conversion, the weight of a Ratti is 121.5 mg, 1 Masha is 8 Ratti, and 1 Tola is 96 Ratti are used for calculating the weight of gemstones.

In this blog, we will learn about Ratti, the traditional Indian unit of weight measurement and how it can help you choose the right gemstone for your astrological needs.

What is Sava, Sade and Pauna in Ratti?

Sava, Sade and Pauna are terms for measuring Ratti. Let’s discuss each of them in detail.

Sava Ratti:

Sava is a quarter or 1/4th part. This means any weight that comes between 0 to 0.35 is called the Sava or Savaya Ratti.

For example, a gemstone with weights such as 4.01, 4.15, 4.25, or 4.34 will be considered Sava Chaar Ratti.

Sade Ratti:

Sade or Saadhe is a half or 1/2th part. All the weights that come between 0.36 to 0.75 are called Sade Ratti.

For example, 5.36, 5.40, 5.57, or 5.73 will be considered Saadhe Panch Ratti for a gemstone.

Pauna Ratti:

Pauna Ratti: Pauna is a third-quarter or 1/3th part. The rest of the weights that fall between 0.76 to 0.99 are called Pauna Ratti.

For example, 3.77, 3.87, or 3.99 will be considered as Paune Teen Ratti.

The Difference between Ratti & Carat

Carat is an internationally acclaimed unit of measurement for precious stones like diamonds. The term Carat was coined in 1907 at the Conference on Weights and Measures.

1 Carat is equal to 0.200 grams or 0.007 ounces.

1 Carat = 1.11 Ratti 

1 Ratti = 0.90 Carat 

How much Ratti (weight) of Gemstone should be worn?

When you decide to wear a gemstone, you must consider 4 major factors —

  • The current body weight of the wearer
  • Quality of the gemstone
  • The size of the gemstone should be big enough to make skin contact
  • A gemstone should not hinder the wearer’s lifestyle 

The common advice from astrologers is that the Ratti of a gemstone should be equal to 1/10th of the wearer’s weight.

For instance, if you weigh 50 kg, the least weight of the gemstone is 50/10 = 5 Ratti, so this must be worn. 

In astrology, the ideal weight of gemstones falls between 4 to 8 Ratti. Many astrologers disapprove anything below four or above eight. Either it will turn too small or too heavy for wearing purposes.
