Most diamonds, although appearing colorless, actually have slight tones of yellow or brown. As these tones become more easily apparent, the rarity and cost decrease. Ideal cutting dramatizes the rare splendor if a diamond because it produces such dazzling brilliance.
Practically all diamonds contain naturally occurring internal characteristics called inclusions. The size, nature, location and amount of inclusions determine a diamond's clarity grade and affect its cost. One unique advantage of the Ideal Cut is that its sparkle can mask otherwise noticeable inclusions.
The Ideal Cut Diamond refers to a diamond that has been cut to exact and mathematically proven proportions. Its symmetry, with 58 exactly placed facets, produces the ultimate lustre and beauty. A very well cut diamond will reflect light internally from once facet to another resulting in a brilliant display of “fire”.
GIA cut grades range from Excellent, Very Good, Good, Fair and Poor. Grading scales cover the effects of proportions on optical performance, durability, weight ratio, polish and symmetry.
Also known as Carat Weight is the standard unit of weight used for gems. Each carat (ct.) is equal to 0.200 grams (200 milligrams). Diamonds are weighed to 1/1000 of a carat (0.001) and rounded to the nearest 100th or point. Gems weighing more than 1 carat are usually expressed in carats and decimals.
The cost for each carat of a diamond's weight. To find the total cost of the diamond, you will multiply the per-carat price by the weight. For example, a diamond at 1.25 CT for $3000.00 per carat would be $3,000/ct x 1.25 ct = $3,750.
The term, “Total Weight”, refers to the combined weight of all the diamonds in a piece of jewelry. When you present jewelry set with more than one diamond, it is necessary to make sure the guest understands whether you are describing the weights of individual diamonds or the total.
