GIA 4CS OF DIAMOND QUALITY

WONDER OF NATURE

There is no other gemstone quite like a diamond. It is found in the most remote places on earth, and the fact that it forms at all is something of a miracle. It takes about one ton of rock to recover less than half a carat of rough, making diamond one of the rarest and most desired gemstones in the world. A diamond is a testament of endurance and strength – and not surprisingly, the ultimate symbol of love.

TREASURE OF TIME

Every diamond is unique. Each reflects the story of its arduous journey from deep inside the earth to a cherished object of adornment. Yet all diamonds share certain features that allow us to compare and evaluate them. These features are called the 4Cs.

Color

The GIA Color Scale extends from D (colorless) to Z (light yellow or brown).

Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry are nearly colorless with tints of yellow or brown.

Color grades are determined by comparing each diamond to a master set. Each letter grade represents a range of color and is a measure of how noticeable a color is. Fluorescence Some diamonds can emit a visible light when exposed to ultraviolet radiation, but fluorescence is not a factor in determining color or clarity grades. However, a description of its strength and color is provided on GIA Reports as an additional identifying characteristic.

cut

The GIA Cut Scale ranges from Excellent to Poor.

A polished diamond’s beauty lies in its complex relationship with light. The magnificent display you see is made up of three attributes: Brightness is the combination of all white light reflecting from the surface and interior of a diamond. Fire describes the “flares” of color emitted from a diamond. Scintillation describes the pattern of light and dark areas and the sparkle you see when the diamond, the light, or the observer moves.

A diamond’s proportions affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light, and have increased brightness, fire, and scintillation. GIA assesses these factors for standard round brilliant diamonds in the D-to-Z color range.

CLARITY

The GIA Clarity Scale includes eleven clarity grades ranging from Flawless to I3.

Because diamonds form under tremendous heat and pressure, it is extremely rare to find a diamond that lacks any internal and external characteristics. These characteristics are a by-product of its formation and help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

 

CARAT WEIGHT

One carat equals 200 milligrams in weight.

For diamonds under one carat, each carat is divided into 100 points – similar to pennies in a dollar. 0.75 ct. = 75 points, 1/2 ct. = 50 points.

The 4Cs provide a way to objectively compare and evaluate diamonds, but numbers alone can’t describe a diamond’s mysterious and captivating beauty – for that, you’ll have to visit us to see one for yourself.

Diamond Selection – Value

Hold in the Highest Regard, your Diamond’s Financial Worth

are looking for in an engagement ring..

Ring Styles

In addition to the many shapes of diamonds, there are many styles of
engagement rings and wedding bands to choose from. The key to finding
the perfect ring is to understand her lifestyle and personality.

Styles that match the personality:

  • TRADITIONAL/ELEGANT – The classic solitaire is timeless.
  • OUTGOING/GLAMOROUS – Think dazzling settings that hold the diamond higher, feature sparkling diamonds on the band or a halo setting.
  • OUTDOORS/NATURE LOVER – Consider a ring that holds the diamond lower to the hand or a
    setting that incorporates nature elements like leaves, vines or flowers.
  • ROMANTIC/VINTAGE – Look at ring settings that feature milgrain details, filigree or scrollwork patterns, or dainty bands.
  • CONTEMPORARY – There are many unique, fashion-forward styles that feature non-traditional forms, accents, and metals

Types of metals

Choosing the proper metal for an engagement ring is just as essential as the diamond or gemstone it will hold. Evaluate how your metal choice affects your budget and how it feels in your hand and on your finger.  Consider the amount of care and maintenance that is needed and whether or not the hardware may trigger any skin sensitivities.

GOLD – Gold is the most popular metal used in engagement rings. Gold can be chosen in White Gold, Yellow Gold, or Rose Gold. Gold can range in caratage from 10KT to 22KT. The higher the percentage of gold, the more pure the gold is. Gold is mixed with other metals like silver and copper to create the different types.

PLATINUM – Platinum is a heavy precious metal often used in engagement rings and wedding bands and has a similar look to silver. This hypoallergenic metal is much more rare and expensive than gold. Platinum is often chosen because it can endure much more day to day use than gold or silver.

HIS RING

Long gone are the days where men only had one or two options for
wedding bands. Gunderson’s offers a vast array of styles and metals
