Buying your first piece of diamond jewellery is special. It is emotional, aspirational, and something you want to cherish forever. But with so many options available, how do you really know if what you are buying is authentic and worth the price?

Whether you are choosing a ring for yourself or a gift for a loved one, this guide will help you shop with confidence.

 

1. Look for Diamond Jewelry Certification

A certificate is proof that your diamond jewelry is authentic and graded by a reputed laboratory. Certified jewelry ensures that the diamonds used have been evaluated for their cut, clarity, carat (weight), and color.

In India, the most trusted diamond jewelry certifications are:

• GIA (Gemological Institute of America)

• IGI (International Gemological Institute)

• SGL (Solitaire Gemological Laboratories) - widely used in India 

Every certificate carries a unique number that can be verified on the issuing authority's website.

Always ask for the certificate and keep it safe, as it safeguards the long-term value of your jewelry.

 

2. Check for Gold Purity and Hallmark

A diamond may be authentic, but what about the gold it is set in? This is where hallmarking becomes important.

In India, the Bureau of Indian Standards (BIS) regulates hallmarking of gold. Hallmarked jewelry carries:

• The BIS logo

• The purity mark (for example 18K750 or 14K585)

• The jeweler's identification mark

• The year of hallmarking

Most diamond jewelry is crafted in 14KT (58.5% purity) or 18KT (75% purity) gold, which balances durability with elegance. 

At Swarnam, every piece is BIS hallmarked — because real diamonds deserve real gold.

Tip: The authenticity of hallmarked gold can also be checked through the BIS Care mobile app, where you can verify hallmark details instantly. 

 

3. Know the 4Cs of Diamonds

Understanding the 4Cs will help you buy wisely without overpaying.

Cut: 

• The most important factor for sparkle.

• A well-cut diamond reflects light brilliantly, even if it’s smaller in size.

• Shapes like round, oval, or princess cut each reflect light differently.

Clarity:

• Refers to tiny natural inclusions formed inside the diamond.

• Graded from Flawless (no inclusions visible under 10x magnification) to Included (imperfections visible to the eye).

• VS (Very Slightly Included) and SI (Slightly Included) grades often offer the best balance of beauty and value. 

  Carat (weight): 

• Carat is the weight of the diamond, not just its size (1 carat = 200 mg).

• Bigger doesn’t always mean better — brilliance depends on cut and clarity too.

• A smaller, well-cut diamond can outshine a heavier, poorly cut stone.

   Color: 

• Graded from D (colorless) to Z (yellow or brown tint).

• D–F diamonds are rare and premium, while G–H are near-colorless and of excellent value.

At House of Swarnam, we focus on quality and brilliance rather than size alone. A thoughtfully chosen smaller diamond can shine brighter than a larger one of lower quality.

 

4. Always Ask for an Invoice with a Guarantee

A trustworthy jeweler will always provide:

• Transparent pricing

• Clear return or exchange policies

• BIS hallmark on gold

• Certification for diamond jewelry

An invoice is your written guarantee of what you are buying, so never skip this step.
