Diamonds for Everyone

Diamond History

Shape

Diamonds come in a variety of shapes. Do not confuse cut with shape, cut is what determines how well-cut your diamond is, where as diamond shape is the shape it was cut into.

Round Brilliant- Do not confuse with round. The round brilliant is the modern version of the round which has been refined for maximum shine. The round brilliant is by far the most popular and has the best angles for which to shine maximum brilliance

Oval - Not as popular for solitaires, but very popular for three stone anniversary rings, with two matching diamonds on the sides.

Princess - A square cut diamond that has refractive properties almost near round brilliant. The princess is the preferred square cut shape over radiant.

Emerald - A more traditional shape, the emerald is not as popular as it used as it once was, but has old world elegance to it.

Radiant - Popular before the princess shape was around, the radiant has more facets than a princess, but has the corners trimmed like the emerald shape. This shape is not widely popular.

Heart - Hard to find due to low demand, but some people prefer a heart shape diamond for sentimental purposes.

Marquise - Like the emerald, the marquise is a traditional shape. This is probably the fourth most popular shape behind the round, princess and oval.

Pear - Mostly used in pendants, the pear shape diamond is shaped in a tear drop shape and has fairly good proportions to refract light well.

Diamond Fluorescence

Fluorescence as a term means that a diamond will glow (in blue) under a UV lamp when illuminated. It was used originally in diamond certifications as additional information for identification, but eventually it began to affect the value of the diamonds.

How does Diamond Fluorescence affect price?

The impact of blue fluorescence on price depends on its notice ability. For some higher color stones, fluorescence gives the stone a milky white appearance, which greatly lowers value. In some instances, the fluorescence is hardly noticeable and has minimal impact on the stones brilliance and value.

Fluorescence often adds value to lower color stones as it gives the stones a whiter, brighter appearance. Some buyers regularly pay better prices for highly fluorescent "I" color and lower stones. Yellow fluorescence may require an additional 5 to 10 percent discount. Generally, the higher the quality and price per carat the more strong fluorescence lowers value.

Cleaning

Cleanliness heavily affects a diamonds beauty. A clean diamond is more brilliant and impassioned than the same diamond when it is "dirty". Dirt or grease on the top of a diamond reduces its luster. Water, dirt, or grease on the bottom of a diamond interferes with the diamonds brilliance and fire.

Even a thin film absorbs some light that could have been reflected to the person looking at the diamond. Colored dye or smudges can affect the perceived color of a diamond. Historically, some jewelers stones were misgraded because of smudges on the girdle, or dye on the culet. Current practice is to clean a diamond thoroughly before grading its color.
