Our Four C's of Diamonds guide can help you decide on the most important factors when shopping for a diamond. The word carat derives from the word carob, a Mediterranean seed, which has an extremely consistent weight for measuring. The greater the carat weight, the rarer, and more valuable the diamond becomes.

Some people want to buy the biggest diamond possible. Is this always the right choice? The larger the diamond, chances are the more inclusions it likely has, and because it's larger, these inclusions are typically even more visible than on a smaller diamond. But most importantly, if the diamond cut isn't proportioned correctly, it won't return the maximum amount of light through the top of the diamond. This illustrates that no matter how large the diamond, its cut and proportions determine how brilliant the diamond really is.

Solitaire settings are great if you have a stunning singular stone that has been passed down through the generations as an heirloom, many choose to display it in a classic Solitaire setting. This setting generally allows for the maximum amount of sparkle by allowing light to pass in through the bottom sections of the ring.
