Price: How To Choose For Best Value?

Diamond prices vary greatly. The value of a diamond is determined by counting the 4Cs (Cut, Color, Clarity, and Carat) of an item. The trick is to pick the mix that will bring the price down the most and, to the least degree, alter the appearance. The following is a quick overview of the best value recommendations for Round diamonds:

Cut

When it comes to round diamonds, you don’t cut corners on cut, period. In other words, you probably want something sparkly and fiery, so the payoff will be nice and big. The grade cut has to be of the highest possible. Only Excellent (GIA) or Ideal (AGs), not Very Good, not Good, but only Excellent.

Color

It all gets interesting from here. Masking color is exactly what brilliants are great for, allowing you to go into the color scale safely without noticing any difference! The depth it goes is up to the setting or if you want side stones (and the size of side stones is also relevant). If you are going for a platinum setting and solitaire stone the color should be at least J. If you can go even lower down to K, there is a yellow gold setting. In fact, when diamonds are mounted, you won’t be able to tell the contrasts. However, your wallet will make the distinction.

Clarity

Brilliants also mask inclusions, you can also go down on the clarity scale without anyone noticing. Although SI1 or even SI2 clarity are great value for money, the diamond must be eye clean. Clean to the eye deserves it being a little more clearer, just being clean to the eye just means that the imperfections can’t be detected with an unaided naked eye. If you're buying online but aren’t sure then ask the seller.

Carat

You might not know that diamond prices jump fairly noticeably at full and half carat marks. Below these marks you can save money. Practically, the size difference will be up to 10%. That’s why use this website to compare different sizes and see how far down you’re comfortable going.
