Diamonds

Quality

Our diamond inventory consists of Gemological Institute of America (GIA) and American Gem Society (AGS) diamonds. We like to emphasize great cut and ideal proportions in our diamonds, because they are the main source of brilliancy in a diamond.

We believe it is best to buy diamonds in person. You will be able to feel, touch, and experience the brilliancy of a diamond for yourself. Fill out our Diamond Inquiry form.

Who is the GIA?

The non-profit Gemological Institute of America (GIA) is one of the leading diamond grading laboratories in the jewelry industry. Since 1931, the GIA has educated more than 300,000 jewelers around the world. Its mission is to protect the consumer by encouraging the development of professional and ethical standards. It has developed the most recognized diamond grading, known as the Four C’s (Carat, Color, Clarity, and Cut).

Who is the AGS?

The American Gem Society (AGS) was founded in 1996, and, like the GIA, it is recognized as one of the leading diamond grading laboratories. This laboratory provides what is known as the “Triple O” diamond grading document. Their mission is also to help protect the consumer.

The Four C’s: Choosing a Diamond

The value of a diamond is based largely on rarity and desirability. On this basis, Color, Clarity, and Cut quality, together with Carat weight, comprise the so-called Four C’s that measure a diamond’s value.

Choose your diamond:

Carat

A diamond’s weight is usually stated in terms of carats, and a carat is broken down into 100 points. For example, 50 points is exactly equal to 1/2 carat.

Color

Classification of body color of cut diamonds ranges from colorless to yellow. The Gemological Institute of America (GIA) has developed the following widely used classification system.

Colorless Near Colorless Faint Yellow Very Light Yellow Light Yellow Fancy
D E F G H I J K L M N O P Q R S T U V W X Y Z Z+

Clarity

Clarity is the term used to describe the presence or absence of flaws and blemishes. The Gemological Institute has developed the following widely accepted classification system so that the quality of a diamond can be precisely defined.

Flawless Internally Flawless Very Very Slightly Included Very Slightly Included Slightly Included Included
Fl IF VVS1 VVS2 VS1 VS2 S1 S2 I1 I2 I3

Cut

Improper cutting diminishes the value of any diamond. The ideally cut stone is proportioned so that when light enters it, it is reflected back through the crown or top of the diamond, resulting in maximum brilliance. A diamond that is cut either too deep or too shallow allows an unnecessary amount of light to escape, and thus can cause the diamond to lack “fire” and brilliancy. This would lower the diamond’s value per carat. If you are looking for the best diamond engagement or wedding rings in Boston, Sharon, Mansfield or Walpole please visit any of our stores.
