4 Carat Diamond Buying Guide

Diamond 161739 640

Studies show that 4 carat diamond rings are the envy of those who wear them. Although there aren’t many of these stones on the market (they are extremely rare), the buyers of them often receive a stunning reaction when people see them.

It is very easy for one to get confused and lose sight of what they originally were looking for when presented with all the jewelry options in a store. Presenting the attendant with the specific information will not only make you appear like a wise buyer but also narrow down the search and save time.


1. Shape of the Stone
There are lots of shapes out there but the length to width ratio should be your guide. This will enable you to distinguish the many shapes available. It will also enable you to tell apart diamonds of the same shape, for instance, a wide vs. a narrow marquis, a rectangular vs. a square princess cut. If you are not sure of what you want, choose a shape and ask to view all the pieces they have in their length to width ratios in that shape. Focus on the ones that are 10% within your ideal length to width ratio.

Round diamond stones are the best bet as they show more clarity and brilliance. They suit almost any ring, necklace or earring and never run out of style. For family heirlooms, most people opt for the circular shaped diamond as it can be handed down years to come without the piece of jewelry becoming out of style.

2. Cut of the Diamond
This is the most important feature to look for in a diamond. Most sellers define the cut of the diamond as either; excellent, very good, fair of poor which are standardized by the GIA. Beware of sellers that assign their own cut grades into this array; signature, super ideal. A diamond that’s poorly cut will look dull despite its color and clarity. On the other hand, a well-cut diamond will look outstandingly beautiful due to its ability to sparkle and elude brilliance even when it’s of a lower clarity and color. When on a budget, go for excellent or very good, especially for round diamonds. Go for better or good grades for fancy shapes.

3. Color
Although diamonds come in different colors, distinguishing them is difficult especially to the naked eye. This is especially so when the diamond is set in a ring. Color grading is only effective if done on a white background. It is easier to detect color in large diamonds than in small ones. G-J diamonds have more value for what would normally appear as colorless diamonds. If you are concerned about color, opt for round and princess cut diamonds. Color typically isn’t given the attention that carat weight is when buying a diamond.

4. Clarity
The larger the diamond, the easier it is to detect its imperfections. If you are looking for a flawless piece, opt for VVS2 or higher. It is important to note that brilliant cut diamonds such as round, marquis, princess, cushion, pear, & oval hide visible imperfections (inclusions) better.


Be careful when comparing the price of a particular 4 carat diamond that’s graded by 2 different labs as their judgment is not held to any objective standard. Only buy from a certified lab that has a reliable reputation and the author known for their expertise.
