This range is perfect for the buyer who would like to use their limited budget to focus on supreme colour and clarity or on upgrading to a superior jewellery metal choice like platinum.

Size 0.50-0.53ct

0.5ct marquise diamonds are the milestone of carat sizes that remains the most popular to purchase. Half carat diamonds offers the buyer a stunning stone that emanates scintillating sparkles and rainbow shimmers which prism through the diamond with elegant grace. This carat size is perfect to set in solitaire ring settings, or design your own bespoke engagement ring with Cape Diamonds.

Size 0.55-0.59ct

0.6ct diamonds normally come at a higher price due to their unique size that is in short supply around the world. The 0.55ct - 0.59ct carat range avoids the next price increase while looking strikingly similar to the 0.6ct, which means gaining a sought-after size for a great price that holds a promising resale value.

Size 0.60-0.63ct


View Diamonds

Diamond jewellers never hesitate to purchase 0.6ct diamonds as they are very hard to come by, since supply of these carat sizes is scarce. The 0.6ct diamond offers the buyer a promising resale value due to its uniqueness and is not too much more expensive than the favoured 0.5ct although the difference in size is noticeable.

Size 0.70-0.73ct


View Diamonds

The 0.7ct marquise diamond is one of the most frequently purchased carat sizes in the industry. The 0.7ct marquise diamond promises great value for money while boasting a gorgeous array of scintillating sparkles. Set this beautiful stone in a halo setting to gain that desired 1ct appeal as the smaller diamonds encrusted in the surrounding band enhance the central diamond’s sparkle and size.

Size 0.80-0.83ct


View Diamonds

The 0.8ct marquise diamond is a stunning option for those who are looking for a supreme choice of carat size. The bigger stone lends itself to showing off an incredible showcase of scintillating sparkles. This diamond looks similar to the 1ct but costs substantially less, allowing the buyer to focus on obtaining a high-quality diamond.

Size 0.85-0.89ct


View Diamonds

The 0.85ct 0.89 ct diamond range is usually quoted as options from Cape Diamonds when buyers are searching for a 0.8ct diamond. This is a wonderful idea, because these sizes in stock may be offered at a cheaper price for a larger stone if the colour and clarity combinations are of lower grades. This is perfect for the consumer who prioritizes carat size over other factors.

Size 0.90-0.93ct


View Diamonds

The 0.9ct marquise diamond is a wonderful option for those who have their heart set on a 1ct but whose budget falls just short of the drastic price increase once a diamond reaches the 1ct benchmark. This is a perfect consideration for buyers with limited budgets who want a supreme colour and clarity combination and are after that 1ct appeal.

Size 0.95-0.99ct


View Diamonds

Cape Diamonds is more than likely to quote you on a few 0.95ct options if the client is seeking a 0.8ct - 0.9ct diamond. This is because many times the larger stone may be cheaper and in stock, and the buyer may prefer a larger stone with a lower colour and clarity grade, especially if they are looking to set the diamond in rose or yellow gold.

Size 1.00-1.10ct


View Diamonds

The 1ct marquise diamond is a widely celebrated carat size, desired by diamond-lovers worldwide. It is hard to resist its incredible beauty that sparkles with elegant grace. Set this diamond into a solitaire setting where the 1ct diamond stands out with alluring attraction. 1ct diamonds are always a smart investment choice as they are in high demand and rare to find.

Size 1.15-1.19ct


View Diamonds

The 1.15ct - 1.19ct diamond range is likely to be quoted when a buyer is seeking the 1ct diamond. Many times a slightly larger stone will be cheaper due to lower colour and clarity gradings. This is a perfect choice for those who prioritize carat size over colour and clarity. Near-colourless diamonds blend in beautifully with warmer jeweller metal tones such as rose and yellow gold.

Size 1.20-1.25ct


View Diamonds

The 1.2ct marquise diamond is not much more expensive than the 1ct diamond but lends itself to a higher resale value, especially if the colour and clarity gradings are of supreme selection. This carat size captures the hearts of admirers with its graceful and elegant shine that sparkles with pristine beauty. As the marquise diamond is elongated, it appears to be much larger than a round diamond of the same carat size.

Size 1.50-1.65ct


View Diamonds

The 1.5ct marquise diamond is a stunning option for those who are seeking a supreme carat that speaks of opulence and luxurious beauty. As the marquise diamond is elongated, it appears much bigger than a round diamond or princess-cut diamond of the same carat size. Set this diamond in a halo setting if your heart is set on a 2ct appeal but your budget is limited. The surrounding smaller diamonds augment the central stone’s sparkle and size appeal.

Size 1.70-1.99ct


View Diamonds

If you are searching for a 2ct marquise diamond but you have budget considerations, and if  you would prefer a diamond that is similar in size yet with the highest grade of colour and clarity possible, then this is the perfect carat range for you to consider. The 1.7ct - 1.9ct marquise diamond is a stunning stone that showcases an optimal sparkle and shine and because of its elongated shape, appears much bigger than other diamonds of the same dimensions.

View Diamonds

Diamonds from 2ct to 2.9ct are among the most respected diamond carat ranges in the industry. Due to its uniqueness and rarity, the 2ct marquise diamond will always hold a promising resale value.

The diamond’s stunning sparkle will glow forever and because of its short supply, the resale value is highly substantial. To make a purchase of this magnitude wisely, it is vitally important to know as much about marquise diamonds as possible.
