Know Your Diamond: A Buyer’s Guide

At Chauhan Jewellers, we believe that purchasing a diamond should be a well-informed and exciting experience. Understanding the key factors that determine a diamond’s quality helps you choose a stone that perfectly matches your preferences and budget. Here’s your quick guide to understanding diamonds:

The 4 Cs of Diamonds

Diamonds are graded based on four key characteristics, known as the 4 Cs:

1. Cut
   The cut of a diamond is one of the most important factors in its overall beauty. It refers to how well a diamond has been shaped and faceted. A well-cut diamond reflects light in a way that maximizes brilliance and sparkle.

   • Ideal/Excellent: Maximum brilliance and fire.

   • Very Good: Excellent brilliance with slight variations.

   • Good: Visible flaws, but still beautiful.

2. Color
   Diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond has, the more valuable it is.

   • D-F: Colorless (most valuable).

   • G-H: Near colorless (excellent value).

   • I-J: Faint yellow (good value).

3. Clarity
   Clarity refers to the presence of internal or external imperfections (called inclusions and blemishes). The fewer the imperfections, the higher the clarity grade.

   • Flawless (FL): No inclusions or blemishes visible under 10x magnification.

   • Very, Very Slightly Included (VVS1, VVS2): Minute inclusions that are difficult to see.

   • Slightly Included (SI1, SI2): Small inclusions that are visible with magnification.

   • Included (I1, I2, I3): Inclusions visible to the naked eye.

4. Carat Weight
   Carat weight measures the size of the diamond. One carat equals 0.2 grams. While carat weight affects a diamond’s price, it’s important to remember that two diamonds of the same weight can differ in value based on the other 3 Cs (cut, color, and clarity).

Diamond Shapes

Diamonds come in a variety of shapes, each offering a unique look:

• Round: The most popular shape, known for its brilliance.

• Princess: A square or rectangular cut with sharp corners.

• Cushion: A soft square shape with rounded corners, often referred to as the “pillow” cut.

• Emerald: A rectangular shape with stepped cuts and a large table, offering a sophisticated look.

• Oval: An elongated round shape that gives the illusion of a larger size.

• Asscher: Similar to emerald but square, with a deep pavilion and step cuts.

• Pear: A teardrop shape, combining the brilliance of a round diamond with the elegant curve of a marquise.

• Marquise: An elongated shape with pointed ends, often used for unique or vintage designs.

Diamond Certification

When buying a diamond, it’s crucial to ensure it comes with a certification from a reputable gemological institute. This document outlines the diamond’s 4 Cs and guarantees its authenticity. The most respected labs include:

• GIA (Gemological Institute of America)

• IGI (International Gemological Institute)

• HRD (Hoge Raad voor Diamant)

At Chauhan Jewellers, every diamond comes with a certified grading report, so you can be confident in your purchase.

Diamond Fluorescence

Some diamonds exhibit a phenomenon called fluorescence, where they emit a blue glow when exposed to UV light. While this does not affect the diamond’s overall quality, it may influence its appearance in certain lighting.

• No fluorescence: Most diamonds fall into this category.

• Strong fluorescence: Can affect the diamond’s appearance, making it appear milky or cloudy, although this is rare.

How to Choose the Perfect Diamond for You

When selecting a diamond, consider these tips:

1. Set a Budget: Determine your budget before diving into the 4 Cs. You can still find beautiful diamonds that fit your price range.

2. Prioritize the 4 Cs: Balance the 4 Cs according to your preferences. For example, if you prefer a larger diamond, you may choose a slightly lower clarity.

3. Shape Matters: Select a shape that complements your personal style. Each diamond shape has a different appearance and character.

4. Certification is Key: Always ensure your diamond is certified to confirm its quality and authenticity.

Caring for Your Diamond

Diamonds are durable, but they still need care to maintain their beauty:

• Cleaning: Use a soft cloth to clean your diamond. For deeper cleaning, soak the diamond in warm, soapy water and gently scrub with a soft toothbrush.

• Storage: Store your diamond jewellery separately in a soft pouch or box to avoid scratches from other jewellery.

• Avoid Harsh Chemicals: Keep diamonds away from harsh chemicals or abrasive surfaces that can dull their sparkle.
