What to Look For in Diamond Jewelry

Giving diamonds to a loved one on a special occasion is considered by some to be extra special because of the meanings we attach to the gemstone. Diamonds are durable and can last for several generations, hence the line “diamonds are forever.” Although they are not going to last forever, they will give joy to the recipient for the rest of their life.

So how do you choose quality diamond jewelry?


Carat is one of the 4 Cs diamond experts remind customers when shopping for diamonds. The weight of a diamond is measured in carats, just like gold jewelry is measured in carats. A one-carat diamond is equivalent to 0.2 grams. The bigger the carat, the more expensive the diamond is. When choosing the correct carat while buying a ring for example, you have to take into account the shape and size of the fingers of the recipient.


Diamonds are also classified based on the clarity of the stone. Inclusions and blemishes in the diamonds can only be seen when magnified. Blemishes are found on the surface while inclusions are imperfections found within the piece. Jewelers often use the GIA Clarity Scale to rate the diamonds. A flawless or F diamond has no inclusions and blemishes even when magnified ten times, while I3 (I for Included) has breaks and crystals. Flawless diamonds are of course the most expensive. If you’re on a tight budget, experts recommend an SI1 or SI2 diamond (SI means Slightly Included).





Diamonds come in different colors, the most common of which are colorless diamonds. Rare colors like yellow, blue and red are more expensive than colorless diamonds. Colorless diamonds are graded based on the presence or absence of color, that means that the clearer the diamond, the more expensive it is. Jewelers use the GIA color scale to determine the color of the colorless diamond. D, E and F are the clearest and most expensive.


There are many ways to cut diamonds. The goal of cutting is to reflect light using different angles and proportions. Excellent cuts are bright, polished and have a balanced pattern of light and dark areas. The light that enters the diamond top must be reflected back to the eyes instead of reflecting the light to the bottom or sides of the gemstone. Some jewelers also refer to cut as the shape of the diamond.


If you’re still unsure about the piece you want to buy, ask for certificates from the jeweler. Reputable shops usually have a certificate from the American Gem Society , European Gemological Laboratory, and Gemological Institute of America. There are also other laboratories in the world who grade diamonds but the three mentioned are the most consistent. Never buy loose diamonds when the jeweler can’t present a certificate besides an appraisal.
