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.
