Cut

Cut is one of the most important factors in determining a diamond’s overall beauty. It refers to the proportions, symmetry, and polish of the stone—not its shape. A well-cut diamond reflects light brilliantly, offering maximum sparkle and brightness.

The Gemological Institute of America (GIA) grades round diamonds on a scale from Excellent to Poor. An Excellent cut will reflect light with vibrant brilliance, while a Poor cut may appear dull or lifeless.

At Nespoli Jewelers, we only offer diamonds graded Very Good or Excellent in cut. Each diamond over half a carat is hand-selected to ensure it meets our high standards of quality and radiance.

Color

Diamond color refers to the natural hue found within the stone. While diamonds may look white at first glance, most contain subtle tones of yellow or brown. The most valuable diamonds are colorless, allowing more light to pass through and enhancing their brilliance.

The GIA grades diamonds on a color scale from D (colorless) to Z (noticeable color). Stones graded D–F are considered “Colorless,” while those in the G–J range are “Near Colorless.” Diamonds higher on the scale (closer to D) are more rare and typically more expensive.

At Nespoli Jewelers, we select diamonds that are I color or higher to maintain a consistent level of beauty and quality throughout our collection.

Clarity

Clarity refers to the natural internal features—or inclusions—found in most diamonds. These markings form during the diamond’s creation and are often microscopic. When a diamond appears clean to the naked eye, it's known as “eye-clean.”

We offer diamonds with a clarity grade of SI2 or higher, ensuring they meet our standards for brilliance and visual appeal. For the best balance of quality and value, we often recommend stones in the SI1 to VS2 range. If you're looking for a higher clarity grade, we’ll help you find the perfect match.

Carat Weight

Carat refers to the diamond’s weight. You may also hear the weight of a diamond referred to in points. One carat is equivalent to 100 points, so a 75-point diamond is equal to 0.75 carats. Because they are rarer, larger diamonds have greater value per carat. Therefore, the price of a diamond rises exponentially in regards to its size.
