Buying Guide: Round cut

Round brilliants are very good at masking inclusions and color, which means you can go quite low in terms of clarity and color grades without sacrificing the appearence. Cut, on the other hand, which determines the fire and brilliance should always be of the highest possible grade (Excellent for GIA or Ideal for AGS).

Depth percentage for 0.02 carat Round (2×2×1.06mm)

Depth percentage of Round cut is the ratio of the total depth (measured from table to culet) to its average diameter. The total depth percentage of this diamond is 53%, which is too shallow!.

Depth percentage for rounds is calculated with the following formula:
Depth % = (total depth ÷ average diameter) × 100

0.02 carat Round (2×2×1.06mm) depth %:
Total depth: 1.06 mm
Average diameter = (2 + 2) ÷ 2 = 2 mm
Depth % = (1.06 ÷ 2 ) × 100 = 53%

About Depth Percentage
Depth percentage is one of the most important measurements as it plays a critical role in diamond's brilliance and appearance. If a diamond is cut too deep or too shallow, light leaks out, making the stone less brilliant and fiery. Deep cuts also add hidden weight.

Recommended depth percentage range for Round cuts is between 58% and 62.5%. Diamonds that fall out of this range are generally less desirable and usually best to be avoided.

Face-up size evaluation for 0.02 carat Round (2×2×1.06mm)

The face-up size of this 0.02 carat Round (2×2×1.06mm) is out of normal range for 0.02ct diamonds of this shape. Compared to 0.02 carat Round reference diamond, this diamond appears too big when viewed from the top. You might think that's a good thing, however, it's not. This is a so called spread cut.

Please note: For very small diamonds such as this 0.02 carat Round the size evaluation might be too strict.

A spread cut is a diamond that is cut to maximize spread instead of optimal light performance. From above it looks larger than an ideal 0.02ct diamond. This is not a good thing. Spread cuts are typically too shallow, which allows light to leak out of the stone resulting in less light being reflected back to the viewer's eye.

Spread cuts usually look lifeless and flat, and can sometimes exhibit a fish-eye effect. They may also come with an extremely thin girdle which can easily chip.

The bottom line: Spread cuts generally lack the brilliance and perfection that is expected of a beautiful diamond. Don't be fooled into thinking that you're getting a larger diamond for the money. This could be a rather flat, boring stone.

0.02 carat Round reference diamond

Face-up Area For Rounds

Face-up area is a measure of the size of the diamond when viewed from above. It tells you how big the diamond is at the girdle plane. It's important for a diamond to have sufficient face-up size for its carat weight.

Face-up area at the girdle plane

For more info see carat weight vs face-up size

Face-up Area per Carat

Face-up area per carat is calculated by dividing face-up area of the diamond with its carat weight. It tells you how many square millimeters of the top surface area a diamond is showing or would show for 1 carat weight. This can be useful when comparing stones of similar weights as it tells you how much spread per carat you will get.

Note: Face-up size does not linearly grow with carat weight, which means the heavier the stone, the smaller its face-up area per carat (e.g., 1ct stone will have higher face-up area per carat than 2ct stone).

Face-up area per carat for 0.02ct Round (2×2×1.06mm):
Top surface area = 3.14 mm²
Weight = 0.02ct

Face-up area per carat = 3.14 ÷ 0.02 = 157mm²/ct

Color Recommendation For 0.02ct Round

Round Brilliants don't show color as much as other cuts, so you can go quite a few steps down on the color scale without noticing any difference. The choice of color also depends on a setting:

Solitaire Small side-stones Substantial side-stones
White gold/Platinum J+ I+ same as side-stones+
Yellow gold K+ J+ same as side-stones+
e.g. pave setting e.g. three-stone setting
Note: If side-stones are of any significant size (like in three-stone settings), you should at least match the color of the center stone with the color of the side stones, otherwise the center stone might look out of place (a bit "off-white").

For best value, go with the minimum recommended color for a particular type of setting. Color variations between J graded and higher colored Round cuts are so slight that it's almost impossible to tell the difference, especially when diamonds are mounted. The difference in price, however, can be quite considerable.

Clarity Recommendation For 0.02ct Round

Round Brilliants are great at masking inclusions, so you can go relatively low on clarity scale without sacrificing the appearance, as long as the diamond is eye-clean. SI1 or SI2 clarity offers great value for money.

Note: You can always go lower in clarity, but it's going to get increasingly difficult to find an eye-clean Round below the minimum recommended SI2 grade.

For best value, go with the lowest clarity possible that is still eye-clean. If a diamond is eye-clean, it doesn't matter, if it's flawless or SI2. It will look the same, provided all other characteristics are the same.
About Diamond Clarity
Diamond clarity refers to the presence and visual appearance of the flaws inside a diamond (called inclusions) or on its surface (called blemishes). Clarity tells you to what degree these imperfections are present.

The amount of inclusions and blemishes is directly correlated to a diamond's value. Fewer imperfections mean higher price and vice versa.

Gemological laboratories grade diamond clarity as Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1,VVS2), Very Slightly Included (VS1,VS2), Slightly Included (SI1,SI2), and Included (I1,I2,I3).

GIA and AGS Certified Diamonds

Professional and unbiased assessment of diamond characteristics is stated on a diamond grading report, commonly referred to as a certificate. Certificate, while not 100% reliable, is essential in determining a diamond's value.

The standard for diamond grading is pretty much set by GIA - Gemological Institute of America. They are the most reputable and consistent lab in the industry. AGS (American Gemological Society) is not far behind.

If a diamond is not certified by GIA or AGS, you can be pretty much certain that you are looking at lesser quality than indicated. This puts you in a bad position of not knowing the true diamond characteristics, which almost always results in overpaying. That is why a certificate from a well-respected grading lab is so important.

The bottom line: Make sure to always buy a diamond certified by either GIA or AGS. That's the only way of truly getting the quality you expect.

Diamonds with Blue Fluorescence

Blue fluorescence can have a positive, negative, or zero effect on a diamond. Diamonds in the lower color range (H or lower) can benefit from it, as it can make them look whiter, more colorless. On the other hand, strong fluorescence can cause a stone (especially in the higher color range D-G) to appear hazy or milky under certain light conditions. One of the biggest benefits of fluorescent diamonds is that they generally cost less.

GIA grades fluorescence as None, Faint, Medium, Strong, and Very Strong.

Faint fluorescence will have zero effect on color and overall appearance. Fluorescence of this type is not an issue and shouldn't be a purchasing factor.

Medium fluorescence will in most cases have zero to very small influence on color and overall appearance, however, colorless diamonds can sometimes exhibit negative effects and should be examined in different light conditions before purchasing.

Strong/Very Strong fluorescence requires caution. Generally, it's not a good idea to buy a colorless diamond with Strong/Very Strong fluorescence. As for lower color diamonds, even they can sometimes look hazy with strong fluorescence, so never buy a stone with this type of fluorescence without careful visual inspection.

If you're interested in fluorescent diamonds that have been carefully examined and do not display any negative effects of fluorescence, I recommend Brian Gavin's Blue Diamonds. Those are definitely top of the line and a great value.

Diamonds Without GIA or AGS Certificates

The problem with diamond grading labs other than GIA or AGS is that they are looser and more inconsistent in their grading standards. A GIA color H is an IGI color G and an EGL/HRD color F. The same goes for clarity.

While it's true that IGI, EGL, and HRD diamonds are sold at a discount, you can be certain that the same stones would cost less, if they would be certified by GIA or AGS. Why? Because they would get lower grades and thus lower price. Lower than discounted IGI, EGL, and HRD stones with higher grades.

Diamond merchants use IGI, EGL, HRD, and alike to maximize their profits. They know they can sell diamonds with inflated grades for more, even if they're sold at a substantial discounts. Some merchants also use their in-house certification, usually for the sole purpose of increasing their profits. These kinds of certificates are meaningless.
The bottom line: If you don't want to overpay and want to know exactly what kind of quality you're getting, then avoid diamonds without GIA or AGS certification.

Buying shy

Buying shy means choosing a diamond that falls just under the full-carat or half-carat mark. So instead of 1ct stone you go for 0.95ct; instead of 1.5ct you go for 1.4ct, and so on.

Because diamond prices jump dramatically at full-carat and half-carat weights, you can save a considerable amount of money when buying shy. Going up to 10% down in weight will result in a slight difference in size, but so slight it'll barely be noticed, if at all. To check this for yourself, use this site to compare different sizes.
