The Diamond Ring 0.24 Carat Marquise Cut with Brilliant Cut 18K Yellow Gold combines a regal, crown-inspired design with refined diamond craftsmanship. This ring is crafted from 18K yellow gold and set with 3 marquise-cut diamonds and 8 brilliant-cut diamonds, arranged in a graceful curve like the points of a tiara, with the marquise diamonds rising above the smaller brilliants. The elegant crown shape makes the ring a timeless choice as a stacking ring, a wedding band or for everyday wear.
3 marquise-cut diamonds
The ring features three marquise-cut diamonds with a combined weight of 0.15 carat, each held in its own prong setting. Their elongated, pointed shape forms the crown points of the design. The diamonds have a Top Wesselton color grade and Small Inclusions clarity.
8 brilliant-cut diamonds
Between and below the marquise diamonds sit eight brilliant-cut diamonds with a combined weight of 0.09 carat, each in its own prong setting, adding sparkle to the base of the crown. These diamonds have a Top Wesselton color grade and Small Inclusions clarity.
18K yellow gold
The ring is crafted from 18K yellow gold, giving the metal a warm and luxurious glow. The rich yellow-gold tone beautifully complements the brilliance of the diamonds and creates a classic, timeless appearance.
Its slim, polished band makes the ring comfortable to wear every day and easy to stack with other rings.

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.
