The 4 C's
Color-
D-F is "colorless."
G-J is "near colorless."
K-M are "slightly colored."
N-Y are either light yellow or brown.
G-J are the best grades to look for, since they appear colorless to the eye (only a trained jeweler can see the difference). However, you still get the lower cost benefits!
Clarity-
FL/IF- Flawless, internally flawless.
VVS1/VVS2- Flaws that are difficult, even for a trained jeweler, to see.
VS1/VS2- Flaws that are somewhat difficult, even for a trained jeweler, to see.
SI1/SI2- Flaws that are visible upon close inspection.
I1/I2/I3- Flaws that are visible immediately.
Here, VVS1/VVS2/VS1/VS2 are the best grades to look for. VVS1/VVS2 diamonds sparkle more under light, but cost more. VS1/VS2 diamonds will sparkle also, yet cost less.
Cut-
This is what cut the diamond is, i.e. the shape. There's round, princess, emerald, marquis, etc. Your personal style will determine this, although some cuts (princess and emerald) sparkle less due to their shape.
Carat-
This is what weight the diamond is, i.e. the size. Generally a larger weight corresponds with a larger diamond. So, if you're shopping for size, then you want to go with a larger carat.
I hope that helps! Happy diamond hunting!

The quality of a diamond's cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and color appear to be of better grade than they actually are. The skill with which a diamond is cut determines its ability to reflect and refract light.
In addition to carrying the most importance to a diamond's quality as a gemstone, the cut is also the most difficult to quantitatively judge. A number of factors, including proportion, polish, symmetry, and the relative angles of various facets, are determined by the quality of the cut and can affect the performance of a diamond. A poorly cut diamond with facets cut only a few degrees out of alignment can result in a poorly performing stone. For a round brilliant cut, there is a balance between "brilliance" and "fire." When a diamond is cut for too much "fire," it looks like a cubic zirconia, which gives off much more "fire" than real diamond. A well-executed round brilliant cut should reflect light upwards and make the diamond appear white when viewed from the top. An inferior cut will produce a stone that appears dark at the center and in some extreme cases the ring settings may show through the top of the diamond as shadows.
Several different theories on the "ideal" proportions of a diamond have been and continue to be advocated by various owners of patents on machines to view how well a diamond is cut. These advocate a shift away from grading cut by the use of various angles and proportions toward measuring the performance of a cut stone. A number of specially modified viewers and machines have been developed toward this end. Hearts and Arrows viewers test for the "hearts and arrows" characteristic pattern observable in stones exhibiting high symmetry and particular cut angles. Closely related to Hearts and Arrows viewers are the FireScope (also known as the SymmetriScope), the Ideal-Scope, and the ASET. The Ideal-Scope and the ASET test for light leakage, light return, and proportions. The ASET (and computer simulations of the ASET) are used to test for AGS cut grade. The GemEx BrillianceScope is a machine that tests for direct light performance results of a diamond. These viewers and machines often help sellers to demonstrate the light performance results of the diamond in addition to the traditional 4 Cs. Detractors see these machines as a marketing tools, rather than as having much scientific value.
The GIA has developed a set of criteria for grading the cut of round brilliant stones that is now the standard in the diamond industry and is called Facetware.

First, if you are watching the expense go with better quality and smaller instead of poor quality and bigger. You can always swap the diamond for something bigger in the future if you want to. Next, remember that this whole thing is about the MARRIAGE and not the jewelry. Personally, I would have married my husband and been just as happy without a ring at all. HE was what I wanted, not the ring. If you're putting all the focus on the size of the rock, perhaps you're not thinking enough about the meaning of the ring and should give it some more thought before taking the vows.

This is a quality diamond. What one of the users above said is not true - H is not a poor color. In fact, it is hard to tell the difference between a near-colorless and a colorless unless you are a professional.
The other user above gave a great answer - she was thorough and you should take her advice!

vvs1 is Good almost the best but H colour is poor in certain light it will look yellow E is pretty nice but if you can get a D it will always look brilliant make sure you also get an Ideal cut or close so it will sparke in almost any light
you should never by a diomond from the showcase if you want a nice one thay often have it in a safe or they can order one for you Good Luck

refer to www.robbinsbros.com and look for info on diamonds & settings. You can also try any other major engagement ring retailer website. Everyone of them will have info for you to use.

I can't remember which grade is the best but I think you can seek the gem specialist for advice and maybe you can ask about the certification to prove its authenticity. Hope you get a really good bargain.
