What does the karat of gold mean?
The Fineness or Purity of Gold is described in terms of ‘Karats’ (K or Kt). Pure Gold is 24K. In other words, one Karat is 1/24 of the total purity of the gold. If gold is 18 parts gold and 6 parts other metals, then it is 75% gold = 18K gold (Note: 18 = 75% of 24).
This term is NOT used for platinum or silver.
Why should I trust spectrometer for gold purity testing?
The spectrometer, also known as karat meter, tests the purity of gold without causing any harm to the jewellery item. It is extremely fast, and results are obtained immediately. It can identify all elements or metals in the jewellery item along with their respective weight percentages (composition).
These results are operator independent, so different people using the system will get the same results. The karat meter is recognized by World Gold Council for testing of Gold.

What is meant by the 4 C’s of a Diamond?
Four main value factors used to describe and classify diamond’s quality and value are: carat, cut, colour and clarity. These four elements are known as the 4 C’s.
Carat: Carat is the standard unit of weight for diamonds. One carat equals 1/5 of a gram. Diamonds weighing less than a carat are measured in points (one carat is divided into 100 points).
Cut: Cut refers to the overall finish and proportions of a diamond. A well cut diamond can make light perform in breathtaking ways, resulting in a magnificent display of brilliance, fire and scintillation. The Cut grade is expressed on a scale from Excellent to Poor. Diamonds can be cut into a variety of shapes to bring out their beauty.
Colour: Most gem quality diamonds used in jewellery are nearly colourless, sometimes with a tint of yellow or brown. Among the rarest are the colours D, E & F, and these command top price. The colour scale goes up to Z.
Clarity: Since diamonds form under tremendous heat and pressure, internal and external characteristics are common. These help identify natural diamonds from synthetics and simulants, and also help identify individual stones. Clarity refers to relative absence of inclusions and blemishes.
Flawless is the top grade. These are extremely rare, and command top prices.
