Diamond Jewellery Buying & Price Guide
Introduction
Buying diamond jewellery is both a special investment and a personal milestone. Whether you’re choosing an engagement ring, a pendant, or timeless studs, understanding how diamonds are priced ensures you get the best value for your budget. This guide will help you navigate the essentials of diamond buying, from the famous 4Cs to setting choices and price factors.
1. Understanding the 4Cs
The quality (and value) of a diamond is determined by four key factors:
Cut
The most important factor for brilliance and sparkle.
Well-cut diamonds reflect light beautifully, making them look larger and more radiant.
Grades range from Excellent to Poor.
Colour
Diamonds are graded from D (colorless) to Z (light yellow/brown).
The less color, the higher the value.
Near-colorless grades (G–J) often offer excellent value.
Clarity
Refers to natural inclusions inside the stone.
Graded from Flawless (FL) to Included (I).
Eye-clean diamonds (VS1–SI1) balance beauty and price.
Carat Weight
Refers to the size/weight of the diamond.
Larger diamonds are rarer and priced higher per carat.
Two diamonds of the same carat can vary in price based on cut, clarity, and color.
2. Factors That Influence Price
Beyond the 4Cs, diamond jewellery prices also depend on:
Shape: Round diamonds are generally more expensive than fancy shapes (oval, cushion, princess, emerald, etc.).
Certification: Diamonds certified by trusted labs (GIA, IGI, HRD) carry more value and assurance.
Metal Choice: Platinum and 18k gold settings increase overall price compared to 14k gold.
Brand & Craftsmanship: Designer or luxury brands add premium charges.
3. Smart Buying Tips
Set a Budget First: Decide what matters most—size, sparkle, or quality.
Prioritize Cut: A well-cut diamond will always outshine a bigger but poorly cut stone.
Look for “Sweet Spots”: Slightly below popular weights (e.g., 0.90ct instead of 1.00ct) can save thousands.
Consider Lab-Grown Diamonds: Eco-friendly and up to 40–60% less expensive than natural diamonds.
Buy from Reputable Sellers: Ensure transparency, return policies, and certification.
