0.50ct 18k Yellow Gold Marquise Cut Wedding Ring SB3736

The carat refers to a diamond’s weight, not its size. A well-cut diamond can appear larger than its carat weight might suggest. While carat weight often influences price, it’s important to balance this with the diamond’s cut, colour, and clarity to get the best value within your budget.

Diamond colour ranges from D (colourless) to Z (light yellow or brown). Colourless diamonds (D-F) are the most sought after, while near-colourless stones (G-H) offer excellent value and brilliance. The choice of metal can also enhance a diamond’s appearance—white metals highlight colourless stones, while yellow or rose gold complements slightly tinted diamonds beautifully.

Clarity measures the presence of inclusions or blemishes within a diamond. Many of our customers prefer diamonds with no visible inclusions to the naked eye, offering exceptional value without compromising beauty. The clarity grade is detailed on the diamond’s certificate, allowing you to find the perfect balance of quality and affordability.

The cut of a diamond determines how well it interacts with light, creating the sparkle that makes diamonds so captivating. It’s not the same as the shape; instead, it refers to the precision of the facets. A diamond’s cut grade—ranging from ‘Excellent’ to ‘Poor’—is noted on its certificate. For maximum brilliance, we recommend selecting a cut grade of ‘Excellent’ or ‘Very Good.’

Fluorescence, as noted on a diamond certificate, can affect how a diamond looks under UV light or daylight. Diamonds with strong fluorescence may appear milky or cloudy, which can lower their cost. To ensure your diamond sparkles brilliantly, we recommend opting for a fluorescence grade of ‘Nil’ or ‘Slight.’

A diamond certificate is an independent, expert assessment of its quality and specifications, including carat, colour, clarity, cut, and fluorescence. At Bespoke Diamonds, we only recommend certificates from the most reputable bodies: GIA, HRD Antwerp, and IGI Antwerp.
