The diamond carat weight scale measures a diamond’s weight, with one carat divided into 100 points for accuracy. For instance, a 0.50 carat diamond is equivalent to 50 points, while a 1.00 carat diamond equals 100 points. This system allows for precise comparison between stones of different sizes.

Carat weight can range from very small fractions of a carat through to exceptionally large, rare stones, with certain ranges more commonly seen in fine jewellery.

Less than 0.50 carats: Diamonds in this range are generally more subtle in scale and are often used as accent stones or for delicate, understated pieces.

0.50 to 0.99 carats: This range offers a balanced size with noticeable presence, making it a popular choice for those seeking a refined centre stone without reaching the one carat threshold.

1.00 to 1.99 carats: Diamonds within this range are often considered a classic benchmark for engagement rings, delivering strong visual impact while remaining relatively accessible.

2.00 to 4.99 carats: Stones in this category are more substantial and increasingly rare, offering a more pronounced presence and typically commanding higher value.

5.00 carats and above: Diamonds at this level are uncommon and highly sought after, often reserved for statement pieces and high jewellery due to their size and rarity.
