Should you compromise on color or clarity, is cut important, how does fluorescence affects the stone, and is certification important. We will go over all of these details with you and explain what factors to consider before making a final decision. We will also recommend our top vendors to you to consider while shopping for a diamond. 

Reading two or three articles is not enough when it comes to choosing the right diamond. Furthermore, it is important to be aware of the fact that one grade inconsistency or a slight difference in the proportions of a diamond can have a huge impact on the price of the diamond, and that is where our perspective is critically important.
