The 0.4ct pear-shape diamond is a stunning choice for those couples who are just starting out in life, looking for a carat size that looks similar to a 0.5ct but which costs less. The 0.4ct diamond is the first carat size to obtain a GIA certificate, and is also the first to make a striking impression as the sparkle becomes noticeable when the diamond reaches the 0.4ct benchmark.

The 0.45ct-0.49ct pear diamond is perfect for those who would like the 0.5ct appeal but whose budget dictates a diamond that costs less. The size comparison between a 0.45ct and 0.5ct is nearly impossible to identify yet the price difference is significant.

If you are looking to set a diamond in rose or yellow gold, where carat size is the greatest priority in your purchase, then this carat range is perfect for you. Lower colour grades blend in beautifully with warmer jewellery metal colour tones. The beauty is that diamonds that fall within this size range are cheaper than 0.5ct diamonds that possess supreme colour and clarity characteristics.

Size 0.60-0.63ct


View Diamonds

The 0.6ct diamond is one of the most sought-out carat sizes for any shape, that is eagerly hunted after by diamond jewellers. This is because they offer incredible value for money and hold a wonderful resale value, as 0.6ct diamonds are very uncommonly cut but look incredibly desirable. Set the 0.6ct radiant diamond in a solitaire ring for a striking, bold and beautiful look or surround it with smaller diamonds in a halo setting to enhance the overall sparkle.

Size 0.70-0.73ct


View Diamonds

The 0.7ct radiant diamond is in great abundance, due to the shape of the radiant diamond which looks very much like a raw diamond that has yet to be cut. As less wastage is maintained from shaping the radiant diamond, buyers are getting as much raw diamond material possible for a cheaper price. This means that a 0.7ct radiant diamond compared to a 0.7ct round diamond will look a lot larger due to its elongated profile.

Size 0.80-0.83ct


View Diamonds

The 0.8ct radiant diamond is a highly adored carat size that is in high demand due to its lack of supply and its close-to-1ct appeal. The 0.8ct diamond shines with brilliance and energetic fire. The sparkle is divine and the shine leaves an everlasting impression. This carat size is the perfect choice for those who want a look similar to the 1ct diamond with the most superior colour and clarity that the budget can possibly allow.

Size 0.90-0.93ct


View Diamonds

Diamonds in the 0.9 - 0.94ct range could be easily mistaken for a 1ct diamond but fortunately cost much less. This is the best consideration for those who have their hearts set on achieving as close to a 1ct as possible, while also wanting to obtain the best colour and clarity possible within their budget.

Size 0.95-0.99ct


View Diamonds

Cape Diamonds is more than likely to quote you on 0.95ct - 0.99ct diamonds if you are seeking a 0.8ct diamond, as they do not cost much more. They are also a fantastic option if you love the sparkle of the 1ct diamond but your budget does not meet the major price jump. This is a beautiful choice of carat size if obtaining the highest colour and clarity grading with a limited budget is just as equally as important as achieving the 1ct look.

Size 1.00-1.10ct


View Diamonds

What is more beautiful than wearing a 1ct radiant diamond? The 1ct diamond of any shape is a celebrated milestone in the industry. 1ct diamonds are incredibly rarely mined which means that they will always uphold an impressive resale value. The 1ct radiant diamond shines with regal beauty in solitaire settings, or to enhance the carat size, set this diamond in a halo setting. 

Size 1.20-1.25ct


View Diamonds

The 1.2ct radiant diamond radiates irresistible sparkles and snow-white shimmers with rainbow glimmers that prism through the unique, mirror-reflective kaleidoscope that defines radiant diamonds. Not costing much more than 1ct diamonds, but displaying a noticeable difference in size, this diamond is the perfect choice for those who want to go the extra mile, as a diamond is normally a once-in-a-lifetime purchase. 

Size 1.30-1.49ct


View Diamonds

By considering the 1.3 - 1.49ct diamond, you are avoiding the major price increase at the 1.5ct benchmark, while obtaining a diamond that looks similar to the 1.5ct and holds more value than the 1ct diamond of identical colour and clarity gradings. If you have your heart set on the 1.5ct diamond, but your budget is more suited to this range, use the savings to upgrade on the jewellery metal like platinum or set in a halo to get the 1.5ct look.

Size 1.50-1.65ct


View Diamonds
