Understanding the Diamond 4Cs

The value and beauty of every diamond are determined by four internationally recognized factors.

1. Cut

Cut determines how brilliantly a diamond sparkles.Excellent cuts reflect maximum light, while poor cuts appear dull even if the diamond is larger.

Expert Tip:
Always prioritize Cut over Carat if you're shopping within a budget.

2. Color

Diamond color is graded from D to Z.

Most buyers receive excellent value by choosing G or H color diamonds.

3. Clarity

Clarity measures natural inclusions inside the diamond.Look for diamonds that are "Eye Clean" rather than chasing the highest clarity grade.

4. Carat

Carat refers to the weight—not necessarily the visible size—of a diamond. Buying a 0.90 ct instead of a 1.00 ct can save thousands while appearing almost identical.

Choosing the Right Gold Purity

One of the most common questions buyers ask is whether to choose 14KT or 18KT gold.

14KT Gold

14KT gold offers excellent durability and is perfect for everyday jewellery.

18KT Gold

18KT gold provides the ideal balance between purity and strength, making it the preferred choice for diamond jewellery.
