Where to buy?
Online-only stores will always offer better prices compared to bricks & mortar stores, their main drawback, however, is that you rarely get the opportunity to visually inspect the diamond before purchasing. Luckily, this is not always the case. A few reputable online retailers (see above) are now providing actual Hi-Res photos of the diamonds they're selling, making it easy and safe to shop online. For best value, buy online.

Note: Seeing a high quality photo of the actual diamond before purchasing online is a must. This goes especially for fancy shapes as the market is quite flooded with ugly looking stones.

Additional Diamond Info

Pear cut is a variation of round cut - pointed at one end and round at the other. The elongated shape works great at making the wearer's finger look longer and slimmer. The pear shape also lends itself well to pendants and earrings. Quite brilliant and quite feminine.

Depth percentage for 9.25 carat Pear (18.99×11.44×6.98mm)

Depth percentage of Pear cut is the ratio of the total depth (measured from table to culet) to its width. The total depth percentage of this diamond is 61%, which is OK.

Depth percentage for pears is calculated with the following formula:
Depth % = (total depth ÷ width) × 100

9.25 carat Pear (18.99×11.44×6.98mm) depth %:
Total depth: 6.98 mm
Width = 11.44 mm
Depth % = (6.98 ÷ 11.44 ) × 100 = 61%

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 Pear cuts is between 59% and 65%. Diamonds that fall out of this range are generally less desirable and usually best to be avoided.

Face-up size evaluation for 9.25 carat Pear (18.99×11.44×6.98mm)

The face-up size of this 9.25 carat Pear (18.99×11.44×6.98mm) is within the normal range for 9.25ct diamonds of this shape. Compared to 9.25ct Pear reference diamond (see below), this diamond is of adequate size when viewed from the top.

Diamonds are sold by weight (carats), but it's important to understand that weight doesn't equally translate into physical size, especially spread. Two diamonds of the same carat weight can vary greatly in spread, meaning that one diamond can appear larger than the other, even though they weight exactly the same.

Proper face-up size should play an important role when buying a diamond. When a diamond is set in a ring, your eyes will only see the face-up area, so you should make sure it's of adequate size. You probably don't want a 9.25 carat Pear that looks like a poorly cut 8.33ct.

The bottom line: A diamond must look its weight. This one does.

9.25 carat Pear reference diamond

Since there are no specific ideal proportions defined for Pear cuts, an estimation formula is used to calculate the Pear reference diamond.
Parameters:
Weight: 9.25ct
Depth: 61%
L/W ratio: 1.66
 
Calculated values:
Length: 18.99 mm
Width: 11.44 mm
Depth: 6.98 mm
*Est. face-up area: 158.59 mm²
Note: Pear diamonds with face-up area of within 9% lower and 12% higher than reference Pear diamond area are considered to be of adequate face-up size.
* Estimated Face-up area: Face-up area of Pear cuts is only an estimation (±4%). Due to uniqueness of each stone, it's impossible to accurately calculate face-up area given only a diamond's measurements.

Face-up Area For Pears

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.

Note: Due to geometrical uniqueness of fancy shaped diamonds, it's impossible to accurately calculate face-up area given only length and width. Surface area for pear cuts is therefore only an estimation, usually within 4% accurate.

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 9.25ct Pear (18.99×11.44×6.98mm):
Top surface area = 158.59 mm²
Weight = 9.25ct

Face-up area per carat = 158.59 ÷ 9.25 = 17.14mm²/ct

Color Recommendation For 9.25ct Pear

Pear cuts can show color more than other cuts, so in order to avoid off-white appearance, choose a high enough color grade. The choice of color also depends on a setting:

Solitaire Small side-stones Substantial side-stones
White gold/Platinum H+ G+ same as side-stones+
Yellow gold J+ I+ 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 H graded and higher colored Pear 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 9.25ct Pear

Pear cuts are great at hiding inclusions, so you can go relaively low on the clarity scale, just make sure the diamond is eye-clean. The recommended clarity for Pear cuts is SI1 or SI2.

Note: You can always go lower in clarity, but it's going to get increasingly difficult to find an eye-clean Pear 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 0.94ct; 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 never be noticed. To check this for yourself, use this site to compare different sizes.

Why buy shy? To save money.
