Diamond: An extremely hard, highly refractive crystalline form of carbon that is usually colorless and is used as a gemstone and in abrasives, cutting tools, and other applications.

Anatomy of the Diamond
Crown: The upper part of a cut diamond or gemstone, the portion above the girdle.

Culet: The minute facet on the tip of the pavilion of a brilliant (round) cut stone.

Girdle: The widest perimeter of a stone.

Table: The flat facet on the top of the gemstone, located in the center of the crown.

Diamond Shapes
Shape: Refers to the outline shape of round, square, oval, marquise, etc.

The Four Cs of Determining Diamond Value
Cut: Cut refers to a diamond’s reflective qualities, which are determined by its proportions, symmetry, and polish and which ultimately result in the brilliance of the stone. Cut is the most important of the four Cs as a well-cut diamond allows the light to reflect and refract to its maximum potential. Cut is not to be confused with shape.

Color: Color in a diamond actually refers to its lack of color. Color hinders a diamond’s ability to reflect light. The closer a diamond is to colorless, the more valuable it is. Diamonds that fall out of the white range, such as yellow, blue, or black diamonds, are classified as colored or fancy-color diamonds. As the intensity of a diamond’s color increases, so does its value.

Clarity: Diamonds are created over billions of years by nature, which leaves unique marks on each stone known as clarity characteristics. A diamond’s clarity refers to the absence of such marks. The higher the clarity (or the less “stuff” inside the diamond), the more rare and valuable it is.

Carat: Diamonds are broken down into carats and points: 100 points = 1.00 carat. So a 75-point diamond weighs 0.75 carats. Remember that carat refers to weight, not size, which is measured in millimeters. A buyer should care about how a diamond looks rather than how much it weighs.

Diamond Jewelry Care
Cleaning: Without proper care, diamonds can chip, scratch, or even break. At least once a year, have your diamond jewelry professionally cleaned. Lotions, soaps, powders, perfumes, hair spray, and basic handling can all reduce a diamond’s shine. If the stone starts to look dull, simply soak the piece in warm water with a mild detergent for 20 minutes, then gently scrub it with an extra-soft toothbrush. Clean in a plastic bowl rather than a sink, take care not to use chlorine, and dry the piece with a soft, lint-free cloth.

Selecting Your Diamonds
Caribbean: Beyond the incredible tax-free and duty-free prices, the extensive selections of fine diamonds make the Caribbean an ideal place to purchase a solitaire or a piece of jewelry set with the stones.

Hearts On Fire: Hearts On Fire diamonds are cut using 100x magnification, which is 10 times the industry standard, ensuring that every diamond is cut to exact proportion. Since cut determines the value of the diamond, Hearts On Fire diamonds are the most valuable in the industry.

Sophia Fiori: Inspired by the famous Hope diamond, which is blue, Sophia Fiori is the world’s foremost blue-diamond jewelry designer. Although rare, Sophia Fiori blue diamonds are up to 30 to 40 percent less expensive than white diamonds.

DiVersa: Every DiVersa piece has a tiny magnet embedded in the design, allowing for two completely different looks in one piece of jewelry. DiVersa features blue diamonds and blue diamonds set in gold.
