Forevermark Diamonds

BC Clark is proud to be an authorized Forevermark® jeweler, being able to bring some of the finest, most brilliant diamonds to Oklahoma. Less than one percent of the world’s diamonds are eligible to be inscribed as Forevermark.

The Forevermark Promise

Each Forevermark diamond comes with a promise that it is beautiful, rare, and responsibly sourced. Proof of this promise lies at the heart of every diamond: a unique inscription, invisible to the naked eye.

Selected by hand, less than 1% of the world’s diamonds are eligible to become a Forevermark diamond. During every step of its journey, strict criteria ensure that only the most beautiful diamonds are chosen to be inscribed as Forevermark. Invisible to the naked eye, the Forevermark inscription includes the Forevermark icon and a unique number. The inscription is 1/20th of a micron deep – 1/5,000th the depth of a human hair – and is placed on the table facet of the diamond, using confidential, proprietary technology.

If you are looking for a high-quality diamond, you cannot go wrong buying a Forevermark.

Beyond the 4Cs of Diamonds

Each diamond is individually selected for its color, clarity, cut, and carat weight, but the Forevermark process goes beyond the standard diamond grading. A standard grading report only tells part of a diamond’s story as the 4Cs are only four of the many characteristics of a diamond. A Forevermark diamond is judged by many additional factors. Since every diamond is as unique as a snowflake, even two diamonds with the same 4Cs grade may not be the same and therefore not equally beautiful.

To be considered to be a Forevermark diamond, the rough diamond itself must be of superior quality even before it is cut and polished. Once a diamond arrives at the De Beers Group Institute of Diamonds to be evaluated, the diamond’s polish must have a high degree of transparency to reflect and refract light. The diamond’s cut must be precise enough to result in both outstanding symmetry and durability.

Only those diamonds that meet all the fundamental steps of their rigorous selection process earn the Forevermark inscription, which consists of the exclusive Forevermark icon and a unique identification number.


Buying a Forevermark diamond also offers assurance that it comes from a source committed to providing diamonds with integrity. Going well beyond the international Kimberly Process Certification protocol to identify conflict-free diamonds, Forevermark mines comply with strict financial, social, and environmental requirements. As part of its corporate social responsibility, Forevermark ensures that all employees and communities from diamond-producing areas benefit from legal, safe, and responsible business practices.
