A New Standard Beyond the 4Cs

For women, diamonds are a jewelry of eternal aspiration. Their vibrant sparkle, maximizing the capture of light, captivates any woman. Yet, when choosing this precious gem to accompany us through life, what criteria should we use? Typically, diamonds are selected based on the "4Cs" (carat, color, clarity, cut). However, diamonds selected with a new value standard have now been born. These are the diamonds from "Forevermark."

Forevermark is a new brand from the De Beers Family, the world's largest diamond company. It is a designation awarded only to diamonds that meet the company's rigorous standards, and it is now gaining attention as a new criterion that surpasses the "4Cs."


Rare Diamonds Cared For by Many

Only rough diamonds mined from locations that meet high environmental and ethical standards, in addition to quality, are chosen for Forevermark diamonds. Furthermore, only top-tier diamantaire companies are selected for cutting and polishing these diamonds. Diamonds that have been handled by numerous professionals eventually emit a superior, unmatched brilliance. Forevermark diamonds are also extremely rare, accounting for less than one percent of all diamonds collected worldwide.


The table surface is inscribed with the Forevermark icon and an individual inscription number. This mark, applied using cutting-edge technology, is an incredibly small imprint, one-twentieth of a micron, invisible to the naked eye. This discreet mark, proving that the diamond has been cared for by many hands, is a fitting "seal" for strictly selected diamonds.

Forevermark diamonds have also supported the development of producing countries, including Botswana. From the trusted mining sites built over long periods, to the selection of rough stones with discerning expertise, and the collaboration with skilled cutters—Forevermark diamonds have been carefully protected by a multitude of people. This rare "seal," imbued with the sentiments of many, is truly befitting for a diamond to be cherished for a lifetime and passed down through generations.
