Why Buy Certified Diamonds?
Certified diamonds have been verified for quality, allowing consumers to purchase with confidence based on the attributes of the diamond rather than blindly trusting the sales pitch of the retailer. When armed with a grading certificate, consumers have a pretty good idea of what the diamond will look like without having to see it in person.
Certified diamonds also:
- Hold their value better than their non-certified counterparts, especially for resale and upgrading purposes
- Simplify the comparison process “it’s much easier to compare certified diamonds based on the 4 Cs than it is to rely on visual inspection alone
- Broaden the shopping base to include online retailers, resulting in significant savings
Diamond Certificate vs. Diamond Valuation
In addition, some retailers will try to pass off a diamond valuation as a diamond certificate, when there is actually a significant difference between the two documents. A diamond appraisal is typically prepared by the seller of the diamond to denote the estimated value for insurance purposes, while a diamond certificate is an unbiased analysis of the stone’s quality prepared by a gemological laboratory.
which are considered the most important in determining a diamond’s value:
- Carat weight
Cut is probably the most important, and most challenging, of the four Cs to understand. The brilliance of a diamond depends heavily on its cut.
Most diamonds contain some inner flaws, or inclusions, that occur during the formation process. The visibility, number and size of these inclusions determine what is called the clarity of a diamond. Diamonds that are clear create more brilliance, and thus are more highly prized, and priced.
Colorless diamonds are the most desirable since they allow the most refraction of light (sparkle). Off white diamonds absorb light, inhibiting brilliance.
A carat is the unit of weight by which a diamond is measured. Because large diamonds are found less commonly than small diamonds, the price of a diamond rises exponentially to its size.
