Diamond
The Ultimate Gemstone for Brilliance & Investment
The 4 Cs of Diamond Quality
Are the global standard for evaluating diamond quality.
Understanding these factors ensures you choose a diamond that balances brilliance and value.
Carat Weight
Carat weight measures the diamond's size, with 1 carat equal to 0.2 grams. While larger diamonds are more valuable, a well-cut diamond may appear larger than one with a higher carat weight but inferior cut.
Colour
Diamond color is graded from D (completely colorless) to Z (noticeable yellow or brown tint). Colorless diamonds are the most prized for their icy brilliance.
Clarity
Clarity refers to the presence of internal flaws (inclusions) and surface imperfections (blemishes).
Cut
Cut quality directly impacts a diamond’s brilliance, sparkle, and overall beauty
