We make our jewellery through our network of craftsmen across India, while we source diamonds and gemstones from across the globe.

This stems back to ancient times in the Mediterranean /Middle East, when a carat became used as a measure of the purity of gold alloys (see next Question 5). The purity of gold is now measured also in terms of fineness, i.e parts per thousand. Thus 22 carat is 22/24th of 1000 parts = 916 fineness.

A Carat (Karat in USA & Germany) was originally a unit of mass (weight) based on the Carob seed or bean used by ancient merchants in the Middle East. The Carob seed is from the Carob or locust bean tree. The carat is still used as such for the weight of gem stones (1 carat is about 200 mg). For gold, it has come to be used for measuring the purity of gold where pure gold is defined as 24 carats.

The “Ideal Cut” is a cut based on a specific set of proportions for a round brilliant diamond proposed by gem cutter Marcel Tolkowsky in 1919. While Tolkowsky’s original theories presented only one particular combination of proportions for creating the best balance of brilliance and dispersion, today the American Gemological Society recognizes any diamond falling within a narrow range of proportions and finish quality as being an “Ideal Cut” (also called an “AGS 0” or “AGS triple zero”).

Gold is traditionally weighed in Troy Ounces (31.1035 grams). With the density of gold at 19.32 g/cm3, a troy ounce of gold would have a volume of 1.64 cm3. A tone of gold would therefore have a volume of 51, 760 cm3, which would be equivalent to a cube of side 37.27cm (Approx. 1? 3?).

A newly mined rough diamond looks more like a piece of glass washed up on the beach than like the polished gems sold in jewelry stores. Bringing out their beauty requires the skill and art of a trained diamond cutter.

Gold is made into a large number of different bars of different weights. The most well known are the large ‘London Good Delivery Bars’ which are traded internationally. These weigh about 400 Troy Ounces, i.e. 12.5 kg/ 27 lbs. Each. Others are denominated in kilogram’s, grams, troy ounces, etc. In grams, bars range from 1 g up to 10 kg. In troy oz, from 1/10 tr.oz. up to 400 tr.oz.. Other bars include tola bars and Tael bars.
