When it comes to diamonds, a wealth of information is available at your fingertips. And it’s a good thing, considering they are simultaneously the most popular gemstone and the most difficult to shop for. We aren’t shy about sharing how to get a great deal on a diamond, nor so we have any issues telling our shoppers exactly how to get the engagement ring they want. But by far and away, our favorite thing to talk about is a diamond’s 4 C’s.
Cut – Always buy the very best cut grade you can afford. It’s what gives a diamond its sparkle, fire, brilliance, and life. Without a good cut grade, all the other criteria are useless.
Carats – Shop for a diamond just a leeeetle bit lighter than your ideal carat weight. So a 1.89 carat diamond instead of an even 2 carats. It can save you thousands, and you’ll never be able to spot the difference.
Color – Depending on your diamond’s shape, the color grade that will look best can vary. For round brilliants, Shop for stones in the G/H color range to get an amazing quality without the premium price. For step cuts like emerald, you need to step (pun intended) it up a notch. Don’t go any higher than an F color grade for maximum impact.
Clarity – Again, your diamond’s shape should determine just how high your clarity grade needs to be. Brilliant shapes let you go all the way up to VS2 (and even an eye-clean SI1) and still have a beautiful stone. Cleaner cuts like emerald and asscher kindly request that you look more in the VVS – VS range to maximize your budget and the diamond’s beauty.
