Things That Affect The Value Of 9 Carat Diamonds
The 4Cs:
The value of a 9 carat diamond is influenced by the Four Cs:
- Cut: The cut of the diamond determines its ability to reflect light and thus maximise brilliance. Ideal and Excellent cuts are recommended.
- Colour: The rarer the colour, the higher the price a diamond can command. As a basic guide, diamonds are graded from D (colourless) to Z (light yellow/brown).
- Clarity: Clarity refers to the presence of internal inclusions or external blemishes. Flawless diamonds are one in a million and highly prized.
- Carat: Carat measures the weight of the diamond. A larger carat weight means a bigger diamond, but this is just the beginning; all four Cs play equally crucial roles.
Certification
When you buy a 9 carat diamond, ensure it is certified by a well-known gemmological laboratory such as GIA or AGS. Certification validates the diamond and gives the buyer peace of mind that they are getting exactly what is described.
Visual Impact Comparison
To put that in perspective, the average size diamond used to create an engagement ring is 1 carat, and a 9 carat stone will be much larger than its single-digit siblings. The visual aspect of a 9 carat diamond is second to none, and this is ideal for anyone that truly wants something unique and eye-catching.
How to Buy a 9 Carat Diamond
Setting Selection
The setting selection is important for a 9 carat diamond. Prong settings are one of the more popular types because they allow as much light as possible to pass through, giving the diamond all its glory and fire. Bezel settings, on the other hand, can help protect your diamond and are best for those with an active lifestyle.
Budget Considerations
9 carat is a notable size for diamonds. Setting a realistic budget and ranking the Four Cs according to personal priorities is important. Keep in mind that the quality of colour, clarity and cut can have a big impact on price.
