KARAT VERSUS CARAT!

What is the difference between karat (K) and carat (ct)?

It lies in what they measure:

1. Karat (K) : measures the purity of gold

• • Pure gold is 24K , which means it is 100% gold .
  • An 18K gold alloy contains 75% gold and 25% other metals / (silver, copper, etc.).
  • A 14K alloy contains 58.3% gold , and so on.

2. Carat (ct) : primary unit of measurement for the weight of diamonds and other precious stones.

• • 1 carat is equal to 0.2 grams (200 mg) .
  • A 0.5 ct stone weighs 0.1 g , while a 2 ct diamond weighs 0.4 g .

3. Point (pt) : Another unit of measurement for the carat

• • • A point is a subunit of the carat.
      
    • 1 carat = 100 points
    • Example :
      • A 50-point diamond weighs 0.50 ct (half a carat).
      • A 25-point diamond weighs 0.25 ct (a quarter of a carat) and so on.

👉In summary:

• Karat (K) =    Gold Purity (10K - 14K - 18K -21K)
• Carat (ct) =   Weight of gemstones
• Point (pt) =    Subdivision of carat (1 ct = 100 points)
