International Diamond Laboratories (IDL) has just released the fee structure for its three basic diamond-certification services: the IDL Diamond Certificate, the IDL Compact Diamond Certificate and the IDL Color Certificate.

The IDL Diamond Certificate is a threefold document offering detailed information on the Four C's. It confirms the natural character of the diamond and offers detailed plotting of its internal and external characteristics. Typically, prices range from $50 for diamonds up to 46 points to $100 for a 1.99-carat stone.

The IDL Compact Diamond Certificate is a twofold document offering detailed information on the Four C's. It also confirms the natural character of the diamond and is offered for diamonds starting from 15 points to 4.99 carats. Prices range from $35 for diamonds up to 46 points to $75 for a 1.99-carat stone.

The IDL Color Certificate confirms that the diamond has a natural origin and that it has not been treated. It also provides the carat weight and exact color grade. The 2C Color Certificate is offered for only $12 for diamonds up to 46 points and $20 for stones just under a carat.

Both the Diamond Certificate and the Compact Diamond Certificate come with a complimentary IDL Digicert, an electronic, online-available version of the hard-copy certificate that can be consulted anywhere, anytime by logging in using the certificate's unique number.

IDL offers its clients a discount of up to 25 percent when registering 100 or more stones. In addition, IDL offers downstream services such as sealing, laser inscription and language options at competitive prices to support consumer confidence in diamonds.

The IDL Sealing showcases the diamond in a tamper-proof container. It is fully transparent and clearly summarizes the Four C's. Sealing costs $10 at time of certification and $20 for resealing.

Diamonds can be laser-inscribed for $10 below a carat and $20 above. A choice is offered between the IDL logo accompanied by the certificate's unique number or a personal logo and/or message.

Certificates can be reissued in another language for $10. Currently, IDL certificates are available in English and Arabic.

Prices are effective beginning this month.

IDL services the global diamond and jewelry industry through its offices in Antwerp, Belgium; Dubai, United Arab Emirates; and Mumbai, India.
