This is the first diamond size to obtain a GIA certificate to prove its value. When diamonds reach the 0.4ct size they should always have a nano serial number engraved on the girdle within the diamond to prove its validity. The 0.4ct looks similar in size to the popular 0.5ct cushion-cut diamond, but costs much less.

Size 0.45-0.49ct

The 0.45ct is less expensive than a 0.5ct but looks almost identical. Savings from this price difference may allow the buyer to upgrade the ring to platinum metal or set a halo of small diamonds around the centre stone to produce an impressive glitzy shimmer.

Size 0.5-0.53ct

Half a carat diamonds are the favoured milestone.

Going that extra mile and doing that little bit more than required will surely bring much happiness to a relationship. She will definitely appreciate that extra amount over a half a carat and you will appreciate the small price difference between the 0.55ct diamond and the 0.5ct diamond.

Size 0.6-0.63ct


View Diamonds

Excellent cushion-cut diamonds of 0.6 carats are difficult to find as most diamond cutters will rather cut an average 0.7ct from the rough stone, since there is more money charged in the next size category. 0.8ct and 0.6ct diamonds are the most sought-after carats by diamond dealers in South Africa as they are the rarest of all diamond sizes. 

Size 0.65-0.69ct


View Diamonds

When diamonds are cut above 0.65ct and below 0.7ct they are snapped up immediately by any jeweller as they are probably the best investment of all sizes. A 0.65ct diamond will shine beautifully in a solitaire engagement ring, or you could further enhance its size and shimmer by setting it in a halo design.

Size 0.7-0.73ct


View Diamonds

The 0.7ct diamond is a popular size that is in high demand, especially for cushion-cut diamonds, as the cushion shape is similar to the raw stone. 0.7ct diamonds present one of the best options, boasting great value for money.

Size 0.75-0.79ct


View Diamonds

The 0.75ct cushion diamond avoids the drastic price increase before the 0.8ct benchmark, although looks incredibly close in size to the 0.8ct diamond. Set this carat into a halo setting if you are desiring a sparkling 1ct look and feel.

Size 0.8-0.83ct


View Diamonds

0.8ct diamonds are extremely hard to find at diamond jewellers as it is one of the most uncommon diamond sizes to obtain and is therefore very desirable. They are close in appearance to the 1ct diamond, however, they cost substantially less, making the demand for the 0.8ct diamond even more alluring.

Size 0.9-0.93ct


View Diamonds

The 0.9ct cushion-cut diamond is a stunning choice if you desperately wish to purchase a 1ct diamond, but your budget just does not suffice. The 0.9ct and 1ct diamond look identical but the price difference is noticeable. The 0.9ct diamond is rare, and if you lay your hands on one, you will be fortunate to pay less for a diamond that will be perceived as the most desirable size of all - the 1ct diamond.

Size 0.95-0.99ct


View Diamonds

The 0.95ct - 0.99ct diamond size range boasts prices that are substantially cheaper than 1ct diamonds while looking very similar to the desirable carat milestone. When a diamond reaches 1ct in size, the price substantially increases too, so any savings in this range might be fruitfully used to achieve a superior colour and clarity combination.

Size 1.0-1.1ct


View Diamonds

1ct cushion-cut diamonds reach the size that so many diamond-lovers dream of. 1ct diamonds are exceptional in their rarity and unsurpassed in their beauty. A truly prized possession, the 1ct diamond holds everlasting worth and sentiment. The 1ct diamond promises a most substantial resale value and will forever be an alluring and attractive carat size.

Size 1.15-1.19ct


View Diamonds

The 1.15ct - 1.19ct diamond lends itself to consideration by discerning buyers seeking 1ct diamonds. The slight increase in size may not even be noticed by the budget but is attractive to the buyer as the bigger diamond may hold more prestigious colour and clarity grades or more excellent cut and polish.

Size 1.2-1.25ct


View Diamonds

If you are a diamond lover who pursues size over all other factors and has a budget spend that is likely to afford a 1ct diamond, then the 1.2ct may be an interesting size range for you to consider as the price increase is reasonable, especially if you go for a lower colour and clarity grade. The 1.2ct diamond of supreme colour, clarity and cut will always outclass the resale value of a 1ct with the same characteristics.

Size 1.3-1.49ct


View Diamonds

The 1.3ct - 1.49ct cushion diamond avoids the major price increase once the diamond reaches 1.5ct in size. This range of carat size holds incredible value for money while appearing identical to the 1.5ct diamond’s dimensions.

Size 1.5-1.65ct


View Diamonds

The 1.50ct cushion-cut diamond is a majestic carat size that is very noticeably bigger than the 1ct and very close in appearance to the 2ct diamond. The 1.5ct diamond promises incredible resale value, and the stronger the colour and clarity paired with the 1.5ct, the more lasting worth it will retain. The price difference between the 1.5ct and the 2ct is significant while the comparison to the naked eye is nearly impossible to perceive.

Size 1.7-1.9ct


View Diamonds

1.7ct - 1.99ct diamonds are the closest in appearance to the 2ct diamond without being offered at the price increase that diamonds accrue when hitting the 2ct benchmark. These diamonds are rather uncommon to find at diamond jewellers, but at Cape Diamonds, we go far beyond the call of duty to source a diamond of this size if you’re after a 2ct, but your budget falls just short.

Size 2.0-2.99ct


View Diamonds

It is no secret that a 2ct cushion-cut diamond could possibly be one of the most luxurious and precious pieces of natural treasure that any woman could own. The 2ct diamond is very rare, so its price is justified by the short supply. The high cost, however, promises a substantial resale value, making a diamond of this size a smart and wonderful investment that offers portable and tangible wealth. The 2ct diamond is fit for the queen of your dreams if you are the king of your destiny. 

Size 3-4ct

3ct diamonds are not commonly seen as only very few buyers are in a position to consider a diamond gem of this rare size.

The 3ct cushion-cut diamond comes at a high cost, but you can be confident that Cape Diamonds offers the best prices for GIA certified diamonds in South Africa.
