How a diamond is cut – regardless of shape – is the key to a quality stone. The shape is determined by personal taste, and you should always choose the shape you love but the ideal cut is one only The Diamond Source experts can see.
Diamonds are often cut to maximize weight, not brilliance as we know that every part of a diamond must be cut to exact mathematical proportions in order to achieve maximum fire and brilliance.
When considering cut, we examine the depth of the diamond, table diameter, crown height and angles, pavilion angles, the thickness of the girdle, polish, and symmetry. If those are terms you don’t understand, ask us and we’ll explain. That’s our job!
Color refers to how white (or colorless) a stone appears because the whiter the diamond is more rare, beautiful, and valuable the stone. The grading scale for diamond color is between D (whitest) and Z (least white).
Colorless diamonds are very rare – only about 1 percent in the world qualify — and range from D, E, and F grade. Near-colorless stones ranging between G and J grade are also quite valuable.
Natural Color Diamonds occur in nature in a variety of stunning colors including yellow, blue, pink, orange, and green, and red. These rare and valuable diamonds are a miracle of nature. Bathed in mystique and an aura of sophistication unrivaled by any other gemstone, Natural Color Diamonds are the epitome of luxury.
No two diamonds are alike but clarity is determined by how clean or “included” the stone appears. Inclusions are any visible spots or marks inside the diamond therefore clarity is determined using a high power magnification device. The inclusions of a stone are its fingerprint, and small inclusions will not interfere with the reflection of light or its durability.
Many people believe that a diamond with fewer flaws will appear more brilliant but this is not the case. Brilliance is always determined by the quality of the cut, not the clarity of the stone. If a diamond is clean to the naked eye then the level of clarity will not improve the stone’s visible beauty. The less inclusion, the more rare and valuable the stone.
The weight and size of all precious stones are expressed in carat weight but the Size is the most obvious factor in determining the value of a diamond therefore cut, color, and clarity will dramatically affect the value, no matter the size!
One carat equals one-fifth of a gram. A carat is divided into 100 points, so a diamond of 25 points is equivalent to a weight of ¼ a carat.
