Comparing the Size of 2 Carat and 3 Carat Diamonds.
Today’s blog post aims to compare the size of large diamonds. Our examples all weigh 2 carats and 3 carats. Consequently we have included a variety of different diamond shapes, all based on the 2 to 3-carat diamond size.
Taken on a regular camera, the following diamond photos give a better appreciation of size.
2 Carat Round Brilliant Cut Diamond
The above photograph weighs in at just over 2 carats. The diameter of the diamond is 8mm wide with a depth of 5mm. This is a fairly typical size for a 2-carat diamond. Physical size varies depending on how well proportioned the diamond is cut. A poorly cut 2-carat diamond might appear considerably smaller with much of the weight in the back of the stone. We refer to the appearance of size as the ‘spread’ of the diamond.
3 Carat Round Brilliant Cut Diamond
Our next photograph shows the size of a 3-carat diamond. There is a noticable size increase in the diameter of this diamond when it is measured accurately using a diamond gauge. The diameter measures 9mm with a 6mm depth. A comparison of size to other diamond shapes can be very difficult, with a greater variation in measurements due to differences in model. For example, Marquise cut diamonds can be cut with longer proportions. Other diamonds are cut with broader proportions. For this reason, you will often see a ratio of length : width referenced with a comment on favoured ratios.
A Comparison of 2 Carat and 3 Carat Diamonds
The photographs appearing on the left, are close-up macro photographs of 2 and 3-carat diamonds, appearing with regular proportions.
Furthermore, each photograph shows additional detail – small clarity characteristics appearing within each diamond. Such clarity characteristics determine the clarity grade of any diamond.
Both diamonds feature slight inclusions which are more apparent within much larger diamonds. This is due to the larger table facet size.
It is always advisable to view larger diamonds in person. Where buyers cannot visit, we provide high-resolution photography and videos. To ensure your diamond has been graded to a high standard, it is advisable to ensure your diamond includes a reputable diamond grading certificate from a laboratory such as GIA. (Gemological Institute of America.) The addition of the certificate number on the girdle of the diamond is a useful detail for identification of your diamond.
When it comes to the jewellery design itself, round diamonds give greater consistency for settings. It is advisable to shape a setting, especially for a fancy shape diamond. The cost of a 2 carat or 3-carat diamond demands a specially crafted setting to correctly house the diamond.
Photographing Large Diamonds
As part of our work, we regularly photograph large diamonds for clients. Our diamond photography ensures a full appreciation of a diamond without the need to view in person. Photography comes from two sources. First of all, we have a high-resolution camera which is great for macro-jewellery-photography. In addition, we have a microscope, perfect for revealing the location of inclusions. This can be used to reveal the GIA number inscribed on the girdle of diamonds.
Examples of Fancy-Shaped Diamonds 2 and 3 Carat Sizes
The following photographs show a few additional diamond shapes in 2 and 3-carat sizes. Almost all photographs come stock diamonds sourced for clients.
The Pear-shaped diamond above appears with beautiful proportions. The model of a diamond can vary enormously. As a result, it is very difficult to gain an appreciation for the overall shape purely from dimensions.
Perfectly square Princess cuts suit both square and compass set ring mounts. The 3-carat Princess-cut shown above represents a perfect example of a beautifully proportioned diamond.
In conclusion, despite the size of a 2 or 3-carat diamond, there will be an enormous difference in value. While size remains an important factor, never overlook colour, clarity and cut alongside carat weight.
