This refers to the large flat facet on the top a diamond. If the table facet (the polished flat surface on a diamond) is too large or too small, it will often indicate poor proportions overall, which will affect a diamond's brilliance.
The table percentage is derived by dividing the width of the table by the diameter of the gemstone.
Symmetry refers to the exactness of the shape and arrangement of facets (which are the polished flat surfaces on a diamond).
Symmetry grades include: extremely poor, very poor, poor, fair, good, very good, and excellent.
Few diamonds are available with excellent or very good symmetry, and diamonds with poor to extremely poor symmetry should be avoided. This is an important indicator of the quality of a diamond’s cut.

People typically buy loose diamonds when they’re looking to create custom jewelry and want to hand-pick the gemstones that will be used in their final piece. Instead of choosing a ring, earrings or a pendant “off the rack,” you can buy loose diamonds that match your specifications and ensure every detail of those stones is in line with your expectations. You might buy loose diamonds to fix or upgrade a piece you already have, too. Perhaps a family heirloom is missing an accent stone or you want to switch out your diamond solitaire for a larger diamond with more clarity. Both situations call for a loose diamond backed by the right certification, just like you’ll find at Allurez.
Additionally, some people will buy diamonds as an investment, much the way one invests in gold or other precious metals. The value of diamonds has consistently increased over time, with the per-carat values growing tenfold over the last sixty years, outpacing inflation.
The cost of loose diamonds depends on the 4Cs: carat weight, cut, color and clarity. Think of each characteristic as if it’s on a sliding scale. The closer to perfection you expect each element to be, the more the final cost rises. But you can help control the price by balancing your expectations and prioritizing which of the Cs is most important. If you want a stone with a higher carat weight, perhaps choose a more affordable cut or sacrifice a bit in terms of color. Allurez also offers flexible financing to help bring your dream stone within reach.

There is no single “best diamond” or standardized way to choose a gemstone that’s perfect in every way. Diamonds are graded according to the 4Cs: carat weight, cut, color and clarity. Each of those characteristics is looked at on a sliding scale. For instance, the clarity scale for diamonds includes 11 grades starting with I (“included”) and running all the way up to FL, or Flawless. Obviously, a flawless diamond is desirable, but it’s also rare and very expensive. The best diamond for you will suit your individual needs, including how you want the stone to look and what fits your preferred setting. You can consult with one of our jewelers to help find the perfect diamond for you or use the online search tool.
“Loose cut” refers to a diamond that has been cut and polished but not yet mounted in a setting. Those standalone diamonds are ready to use in custom jewelry, so you can design your own pieces to include the perfect diamond or diamonds for you.
