Carat Weight

Carat is a weight measurement used exclusively for diamonds and gemstones. Donít confuse this with Carat or Karat used for gold purity. Prices go up exponentially with carat weight. 100 points = 1 carat. Half a carat = 0.50ct or 50 points, and so on.

Diamond weights table

Different shaped diamonds will appear smaller or larger next to each other as some shapes by their nature, hold more weight in their depth. For example, a 1.00ct Cushion Cut Diamond (with a square ratio) averages around 5.4mm - 6.2mm long. In contrast, a 1.00ct Marquise Cut Diamond has an approximate length of between 8.97mm - 12.2mm, which is a dramatic visual difference.
