Gemstones in Jewellery

Stones add colour, sparkle, and value to gold jewellery. From real diamonds to decorative CZ — here's what you need to know about each type.

Stone Weight & Gold Weight

This is the #1 thing people don't know: When a piece is weighed on the scale, the weight includes both gold AND stones. When you sell or exchange, you only get paid for the gold weight.

Total weight on scale: 25.0g

Stone weight (kundan + pearls): 5.0g

Net gold weight: 20.0g ← this is what you get paid for

Always ask: "What is the net gold weight after deducting stones?" This should be on your bill.

Diamond Basics — The 4 C's

If buying diamond jewellery, these four factors determine the stone's value:

Carat

Weight of the diamond. 1 carat = 0.2 grams. Bigger isn't always better — a well-cut smaller stone can outshine a large dull one.

Cut

How well the diamond is shaped and faceted. Determines sparkle. Ideal/Excellent cut reflects maximum light. This is the most important factor.

Clarity

How free of inclusions (internal flaws). Ranges from FL (flawless) to I3 (visible inclusions). VS1-VS2 is the sweet spot — clean to the naked eye.

Colour

Ranges from D (colourless, most expensive) to Z (yellow tint). G-H range looks white and is significantly cheaper than D-F.
