Natural diamonds are mined from the earth and come with conflict-free guarantees. Most people buy a natural diamond for an engagement ring. Lab diamonds are grown in laboratories. They are chemically the same as natural diamonds, but machines can tell them apart. Lab diamonds are a good option for those looking for a larger diamond within budget, but don't expect much in resale value. Prices for lab diamonds are trending down as more growers come onto the market.

Set a budget and stick to it. Don't forget to leave some room for the setting.



Color refers to the natural body color of a diamond. The color grade, a measure of a stone's colorlessness determines how much tint of yellow it has. The color scale ranges from absolutely colorless (D color) to light yellow (L color). In general, the less color a diamond has the more money it is, all other factors being equal. Most people find the sweet spot to be in the H and I color range, where no obvious color is visible.

The "carat" refers to the weight of the diamond. The bigger the carat, the more money the diamond. There is no "good" or "bad" carat, it strictly has to do with budget. Some trade off quality to get a bigger rock, while others want the finest diamond and settle for a smaller carat weight.

Most diamonds have inclusions. These are natural microscopic features in a diamond. The clarity grade refers to a stone's relative absence of these clarity characteristics from FL (flawless) to I1 (included) scale. Most people find the "sweet spot" to be VS2/SI1 where the diamonds appear "eye clean".

Don't sacrifice the cut. A diamond's cut also referred to as the stone's "make" is the proportions of its facets and its overall finish. Cut is a result of a craftsman's skill in transforming a rough crystal into a magnificent gem. A well-proportioned (well-cut) stone will create that fire and brilliance of flashing rainbow colors and liveliness. Stick to excellent or DreamStone Ideal.

The report certificates grade the diamond. For natural diamonds, the GIA certificate report is the gold standard. For lab grown diamonds, we recommend IGI.


The polish grade of a diamond describes the overall condition or smoothness of the diamond's surface. The polish of a diamond, while not as important as the symmetry, a poor polish grade may cause the facets to appear dulled or blurred. Look for "Very good" and "Excellent" polish.



The symmetry of a diamond refers to the shape, placement and alignment of the facets. With poor symmetry the facets may have external imbalances that can misdirect light as it travels within the stone. Look for "Very good" and "Excellent" symmetry.



The depth percentage refers to the height of a gemstone, measured from the table to the culet, then divided by the width of the gemstone. The depth is an important factor affecting the brilliance and beauty in a diamond. A gemstone with a depth percentage too low (shallow-cut) or too high (deep-cut) will lack fire and sparkle.




The table percentage refers to the width of the table divided by the diameter of the diamond. The table is an important factor affecting the brilliance and beauty in a diamond. A gemstone with a depth percentage too wide (shallow-cut) or too small (deep-cut) will lack fire and sparkle.


Table %


The ratio is the length of the diamond divided by the width. The ratio is not relevant for round diamonds, but is a factor to consider for all other shapes. A bigger ratio means a longer diamond, while a smaller ratio is a wider diamond. Each shape has its own recommended ratio.

Length to Width Ratio


Fluorescence refers to whether or not a stone will produce a color reaction when exposed to long-wave ultraviolet (UV) light (such as the light that comes from black light). None and faint is considered more desirable for diamonds graded D through G, and medium and strong can make diamonds H color and lower look whiter.
