THE 4 Cs YOU SHOULD CONSIDER

Carat

Carat is the unit of measurement used to express the weight of a gemstone. One carat is equivalent to 200 milligrams. Larger gems are rarer, making them more valuable, but the carat weight is just one factor in determining a gem's value.

How to Measure?

To measure the carat weight of a gemstone using a ruler, start by placing the gemstone flat on a surface and aligning it with the ruler. Measure the widest part of the gemstone, which will give you the diameter in centimeters. For instance, a gemstone that measures 0.65 cm across is approximately 1 carat, while one that measures 1.3 cm is around 2 carats. By comparing your gemstone’s size with these measurements, you can estimate its carat weight easily, even if you’re new to gemstones.

Clarity

Clarity refers to the absence of internal flaws or inclusions within a gemstone. The fewer the imperfections, the higher the clarity, and the more valuable the gem.

Types of Clarity:

  • Flawless : No flaws, very rare.
  • Very Slightly Included : Tiny flaws, hard to see.
  • Slightly Included : Small flaws, slightly visible.
  • Included : Visible flaws, affect appearance.

Color

Color is a key characteristic in gemstones, affecting their beauty and value. The most desirable gems have rich, vivid, and evenly distributed color.

Types of Gemstone Color:

  • AAA: Best color, intense and vivid.
  • AA: Excellent color, strong and even.
  • A: Good color, moderate intensity.
  • B: Fair color, less vibrant.

Cut

The cut of a gemstone impacts its brilliance and sparkle. A well-cut gem reflects light beautifully, enhancing its appearance.

Types of Gemstone Cuts:

Round Cut, Princess Cut, Emerald Cut, Oval Cut, Pear Cut, Cushion Cut, etc...

Natural vs Heated

Heated Sapphire: Enhanced through heat treatment to improve color and clarity. More affordable and common, with vibrant colors and fewer inclusions.

Natural Sapphire: Untreated and natural, offering original colors and natural inclusions. Rarer and often more valuable due to its authenticity.
