Diamond Buyer's Guide
How Do I Buy a Diamond
We sell our diamonds LOOSE in the unmounted state so that you can personally compare many diamonds and properly judge COLOR, CUT, CLARITY, and CARAT WEIGHT. It's the way we buy diamonds, it's the way you should buy your diamond.
The 4 C's
Diamonds are found with a range of colors, from light yellow or brown through no color at all, the rarest.
GIA's diamond D-to-Z color-grading scale is the industry's most widely accepted grading system. The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z. Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.
We specialize in perfectly cut diamonds. While most diamonds are cut to maximize weight, our fine diamonds are cut for maximum brilliance in strict accordance with stringent cutting proportions. Cut is by far the most important of the 4C's. A diamond cut to proper proportions allows the greatest amount of light to be reflected for maximum brilliance. Our diamonds are so perfectly cut they reflect up to 93% of incoming light. Average diamonds don't even come close. Don't be fooled by lesser quality, poorer cut stones. Diamond cutting quality can affect price by over 40%!
The fewer imperfections in a diamond, the better. A flawless diamond is EXTREMELY rare and valuable.
Diamond clarity refers to the absence of inclusions and blemishes. Natural diamonds are the result of carbon exposed to tremendous heat and pressure deep in the earth. This process can result in a variety of internal characteristics called 'inclusions' and external characteristics called 'blemishes.'
Evaluating diamond clarity involves determining the number, size, relief, nature, and position of these characteristics, as well as how these affect the overall appearance of the stone. While no diamond is perfectly pure, the closer it comes, the higher its value.
A carat is a measure of weight, which also indicates size. Diamond carat weight is the measurement of how much a diamond weighs. A metric "carat" is defined as 200 milligrams.
Each carat can be subdivided into 100 'points.' This allows very precise measurements to the hundredth decimal place. A jeweler may describe the weight of a diamond below one carat by its 'points' alone. For instance, the jeweler may refer to a diamond that weighs 0.25 carats as a 'twenty-five pointer.' Diamond weights greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as 'one point oh eight carats.'
