Diamond Ring 0.40 Carat Brilliant Cut 18K White Gold
The Diamond Ring 0.40 Carat Brilliant Cut 18K White Gold combines a delicate, contemporary design with refined diamond craftsmanship. This ring is crafted from 18K white gold and set with a total of 21 brilliant-cut diamonds: a trio of larger diamonds forming a small cluster at the center, with smaller brilliant-cut diamonds set along both shoulders of the band. The sparkling cluster and the pavé band make the ring a timeless choice as an engagement ring, a promise ring or for everyday wear.
3 brilliant-cut diamonds at the center
At the heart of the ring sit three brilliant-cut diamonds with a combined weight of 0.17 carat, each held in its own prong setting and grouped together in a playful cluster. Together they create a bright, eye-catching focal point. These diamonds have a Top Wesselton color grade and Small Inclusions clarity.
18 brilliant-cut diamonds along the band
The shoulders of the band are set with 18 brilliant-cut diamonds with a combined weight of 0.23 carat, placed closely together in a pavé setting. They add a continuous line of sparkle leading towards the center cluster. These diamonds have a Top Wesselton color grade and Small Inclusions clarity.
18K white gold
The ring is crafted from 18K white gold, giving the metal a cool and luxurious shine. The bright white-gold tone beautifully complements the brilliance of the diamonds and creates a clean, timeless appearance.
Its slim, polished band makes the ring comfortable to wear every day and easy to combine with other fine jewelry.

The 4C's
The 4C's of a diamond are the four key characteristics that determine the quality and value of a diamond: cut, carat weight, color, and clarity. Together, these four characteristics are used to evaluate the quality and value of a diamond, and are considered when determining a diamond's price.
Carat
The weight of a diamond is expressed in carats and points (1 ct = 100pt). ‘Carats’ come from ‘Carob’ seeds, which were originally used for their constant weight in nature (1 ct = 0.2 g). The carat and the color are the factors that influence the most the final price of the diamond.
Clarity
The clarity is a gemstone's relative freedom from internal imperfections. These imperfections are observed with a x10 magnifier ('loupe') and affect the final value of the diamond differently.
Color
Diamonds are found in nature in different colors. White diamonds can be more or less yellow and are categorised with a letter between D (commonly known as ‘River’) to Z . The different naming systems vary depending on the certifier. Diamonds are also found in all colors; the rarest colors are classified as Fancy-colored diamonds.
Cut
The cut is the diamond’s shape. A cut grade describes the proportions of the cut and the quality of its symmetry and polish. A perfect cut makes the best sparkle.
