Whether you are looking for an engagement ring or a diamond necklace for her birthday, understanding how diamonds are valued, as well as what specific diamond you prefer, is an important first step. When it comes to finding the perfect diamond, there is not one answer, only the combination of the 4c’s of diamond buying that are important to know. Find the information you need on how to buy the perfect diamond for you in Allen’s Jewelers Diamond Buyer’s Guide.

The 4C’s

Some people are less concerned about a diamond’s color or brilliance and are simply looking for the largest looking diamond they can find in their budget. Others prefer a finer stone, with a whiter color and higher clarity, regardless of size or weight. Some people prefer colored stones, from chocolate diamonds to yellow canary diamonds. Yet others are looking for a specific shape, such as traditional round or the more unique triangle. Learning about the 4C’s and the combination important to you will ensure you find the diamond you are looking for.


Cut describes the proportions and angles of a diamond, not to be confused with the shape. While nature determines the other three characteristics, it takes a Master Diamond Cutter to reveal a diamond’s true beauty with the proper cut. Diamonds that are cut too too shallow may appear larger, but a shallow cut leaks light through the side or bottom, resulting in a lackluster appearance and diminished value. A cut that is too deep also detracts from the brilliance and sparkle of a diamond. A properly cut diamond reflects light from one facet to another and projects the light through the top of the stone, known as the stone’s brilliance.

Diamonds are available in a variety of shapes including round, square, pear, heart, marquise and oval. There are also more rare and unique cuts such as triangle, barrel, princess, emerald, and radiant cut.


White-colored diamonds remain the most traditional, although over the years colored diamonds in a wide variety of colors have become popular. Diamonds are graded on a color scale implemented by the Gemological Institute of America (GIA), which ranges from D for colorless, to Z for color. Color differences can be so subtle that diamond colors are graded under controlled lighting conditions and are compared to a master set for accuracy. While truly colorless diamonds, graded D, are treasured for their rarity, diamond color preference is ultimately very personal.

Each diamond forms in Nature over periods from 1 billion to 3.3 billion years, ensuring each diamond is as individual as the person who wears it. Naturally occurring inclusions such as minerals or fractures are identifying characteristics created while diamonds are formed in the earth. Master IJO Jewelers use magnification to view diamonds at 10x their actual size so these tiny inclusions are more easily seen. Inclusions are measured on a scale of perfection, known as clarity, the more rare and valuable it is. The less centrally located the inclusion in the diamond the less it impacts the dispersion of light.

Carat Weight

Contrary to popular belief, carat is a diamond’s measure of weight, not size. One full carat is equal to 100 points. A ¾ carat diamond is the same as 75 points. Since larger diamonds are found less frequently in nature, a one carat diamond will cost more than twice a ½ carat diamond (assuming all other characteristics remain consistent). The cut and the mounting can make a diamond appear larger than its actual weight. Besides a properly proportioned cut for the carat weight, the right mounting will optimize its beauty.
