Diamond Shapes

Gunderson’s offers an overwhelming variety of remarkable shapes and designs.

Round

A timeless silhouette, the faceting pattern shows the best fire and brilliance, cut to feature excellent light dispersion.

Emerald

An exceptional shape with beveled corners and step cuts producing a hall of mirrors effect.

Radiant

Square or slight rectangular shape with trimmed corners, cut to have a complete brilliant-cut facet pattern to maximize fire and sparkle.

Pear

A hybrid of the round and marquise shape, this brilliant-cut diamond offers a graceful flattering outline with its tapered point and rounded end.

Asscher

This shape is similar to the emerald, but in a square shape with larger step facets, cut corners, a higher crown, and smaller table, producing more brilliance.

Marquise

The shape of a marquise diamond can maximize carat weight, giving the illusion that the diamond is larger than it actually may be.

Princess

A sophisticated square shape, this fancy-cut diamond creates the illusion of a larger stone and possesses the gorgeous sparkle of a round brilliant diamond.

Oval

This flattering oval shape is symetrical and exhibits similar brilliance as the round diamond while accentuating long slender fingers.

Cushion

Also known as “pillow-cut”, these have the appeal of a square cut diamond with larger facets and soft, rounded edges, giving a romantic feel.

Diamond Selection

Diamonds are among nature's most precious and beautiful creations.

The Four C's

COLOR – Diamonds are valued by how closely they approach colorlessness – the less color, the higher their value (with the exception of fancy color diamonds). Most diamonds found in jewelry stores run from colorless to near-colorless, with slight hints of yellow or brown. Slight differences in color make a big difference in diamond quality and value.


CLARITY – Because diamonds are formed deep within the earth, under extreme heat and pressure, they often contain unique birthmarks, either internal (inclusions) or external (blemishes). Diamond clarity refers to the absence of these inclusions and blemishes. The GIA International Diamond Grading System assigns a diamond’s clarity in ranges from flawless (FL) to diamonds with obvious inclusions (I3). Diamonds without birthmarks are rare – and rarity affects a diamond’s value.


CUT – Cut determines a diamond’s fire, sparkle, and brilliance. No matter what shape, the cut of any diamond has three attributes: brilliance (the total light reflected from a diamond), fire (the dispersion of light into the colors of the spectrum) and scintillation (the pattern of light and dark areas and the flashes of light, or sparkle, when a diamond is moved). From a value factor, cut refers to a diamond’s proportions, symmetry and polish.


CARAT WEIGHT – Diamonds are weighed in metric carats with one carat equal to 0.2 grams. One carat is also divided into 100 points, for example, a 50-point diamond weighs 0.50 carats. While carat weight is important, customers also care about the look, or size, of their diamonds.

Colored Diamonds

Diamonds have been discovered in every color of the rainbow, from rare (brown and yellow) to the rarest (red and purple).

Colored diamonds are graded differently than colorless with the three main attributes being: rarity of color, intensity of color, and size of stone. Gunderson’s is an active and proud member of the National Color Diamond Association. The NCDIA is a non-profit, membership-based organization with multi-national members including mining companies, diamond and jewelry manufacturers,

Its All About Color

Natural color diamonds are true miracles of nature, formed deep within the Earth millions of years ago. Now, having found their way to the surface, they are visible for all of us to see. These gems are rare and renowned for their beauty, encompassing a wonderful palate of color including pinks, champagnes, cognacs, yellows, greens and blues, oranges and even reds.

 

Strength Of Color

The strength of color is one of the most important factors in determining the value of a natural color diamond. The value of a natural color diamond increases with the intensity of the most prominent color within the diamond. In an attempt to bring some uniformity to the industry description of natural color diamonds, gem analysis laboratories have developed the fancy color diamond color scale to classify the strength or intensity of a diamond’s color.

 

Virtually every color, shade and hue the mind can imagine, nature has created within a marvelous natural color diamond. The range of color varieties is almost inexhaustible. The NCDIA is committed to present, on a continuing basis, the full range of color categories expressed by these wonderful natural creations.
