Diamond Education
F.A.Q.
We sell diamond stud earrings in every quality and price range, but we do have a preference for the best value.
For those who can afford it, we recommend an excellent cut diamond of G-H color and "eye-clean" clarity. This is a
moderately priced diamond, but earrings of this quality will produce the same dazzling shower of light as those costing
thousands of dollars more. There are three simple reasons: first, it is the excellent cut that breathes life and sparkle
into a diamond. Second, most experts agree that a G-H color appears colorless when mounted, so spending more for D-E-F
color diamonds isn't necessary. Third, a diamond of SI2 clarity is "eye-clean", meaning it has no flaws visible to the naked
eye, but costs a lot less than the higher clarity grades.
Excellent bargains with only a slight compromise in beauty can be found in the I1 Clarity range as well, as long as the cut is good and the color is in the G-H range.
For those who are on a budget, don't feel embarrased to buy diamonds of a lower quality. All diamond earrings sparkle when they are worn on a woman's ear, and let's face it: for the same price, many women would rather wear 1 carat studs of a lower quality than 1/2 carat studs of a higher quality. If you are not satisfied with the quality, you can always return them with our easy 30-day return policy or trade-up to a higher grade later with our lifetime trade-in warranty.
Our diamond earrings are guaranteed to be the best quality available for the price: we sell the same color, clarity and cut grades for about 25% less than the typical "sale" price in a retail jewelry store (and other internet stores), and we back it up with our lowest price guarantee.
More than any other attribute, it is the Cut that makes a diamond brilliant and beautiful. A diamond that is well cut reflects light internally and displays a dazzling shower of light back through the top of the stone. Learn the Secret to a Brighter Diamond

Fast Fact:
Earrings from DiamondStudsOnly are carefully inspected to represent the best cut standards for the price. When viewing a diamond, look directly into the center:
if there are dark facets in the center or a dark ring around the center, or if the diamond appears opaque, it is probably due to poor cut
The finest diamonds are colorless, rare and expensive. On the GIA grading scale below, D-F are considered colorless, G-J near colorless and any grade K or below shows an increasingly yellowish tinge. Beyond the preference for a whiter stone, however, the color of a diamond does not affect its brightness or sparkle.
Fast Fact:
Most experts agree that, when mounted, diamonds in the "G-H" range appear colorless, and represent a much better value than "D-F" stones which command significantly higher prices.
Diamonds with fewer flaws (inclusions) are rare and therefore more highly prized. In many cases, these flaws don't detract from the beauty of the diamond because they are invisible to the naked eye.

F-IF Flawless, internally flawless. No flaws internally or externally. Extremely rare and beautiful diamonds. |
VVS1-VVS2 Very, very slightly included. Very hard to see inclusions under 10X magnification. Diamonds of excellent quality. |
VS1-VS2 Very slightly included. Inclusions usually not visible to the naked eye. Cheaper than VVS1 or VVS2 grade loose diamonds. |
SI1-SI2 Slightly included. Inclusions visible under 10X magnification and might be visible with the naked eye. Good value. |
I1-I2-I3 Included. Inclusions (maybe large feathers or large included crystals) obvious under 10X magnification. May affect transparency and brilliance. |
Fast Fact:
Any grade "SI2" or above has inclusions that are "eye clean", not visible to the naked eye. An "I1" grade can be an excellent value, particularly if the inclusion is on the outer edge.
"I2" grades can still exhibit a fair degree of fire and light. "I3" grade diamonds are noticeably more opaque or dark to the naked eye.
The weight of diamonds are measured in carats. One carat is equal to 1/142 of an ounce. Most people think of carat weight as the size of a diamond. However, two diamonds of the same weight can look completely different in size. If a diamond is cut deep and narrow, it will look much smaller than another diamond of the same weight that is cut shallow and wide.
