Welcome to Tradeshop Incorporated's Diamond Info Area.
Diamond grading standards fall into four distinct categories, the "Four C's":

Think of these as sliding scales

If you just got the best price on an un-certified ugly diamond listen up!
If you buy a diamond with a poor cut it will cost you, and that is up to 25% of the value of the diamond! Most store folks just talk clarity and color when there is so much more to what makes a diamond wonderful. Buying remotely can be scary, and we know that. We are trained professionals who inspect and verifiy everything along the way, so your diamond and your experience here is marvelously memorable. Oh yeah, when trading up if yer diamond is not certified the grading is "up in the air"... Be smart, buy certified major diamond to protect your dollars.

Consider that the color and the clarity are but half the story, all the catagories in this list in harmony determine the grading, and indirectly the pricing... Lowering one grade in clarity can greatly reduce the cost of the stone, and in the upper grades (VVSI - IF) it's fairly in detectible except in controlled laboratory conditions... Your job is to find "appearant perfection" without paying too much! Compare prices and values, you've been paying way too much elsewhere! I guarantee the more you learn the more you'll agree...
The diamond industry uses very specific grading standards to set a diamond's value. Grading standards reflect "very subtle" gradations of differences---a small carbon spot, slight shift in color, or small imperfection in the cut or polish of the diamond will significantly affect its value. Once a stone gets above VS in clarity it generally appears to the unaided eye to be "perfect"... Here's some basic information to help you in understanding grading, and the four sliding scales in grading... Paying a premium price for undetectable subtile differences in higher grades isn't necessary, Buying a beautiful stone does not mean paying for a "perfect stone" or tossing two month's salary away either... Here's a much needed common sense practical guide to diamonds. Information instead of emotion, isn't that a nice change of pace? {Grin}...

You might think if you can't see the imperfections in a VS-1 why take the clarity/cost hit for a VVS-1 or "Flawless"... Debeers says you need to consider spending two month's salary, I'll offer "with a bit of knowledge and learning you can easily save half of what you might have spent"... It's never been about how much you spend to measure your love, so throw that in the garbage where it belongs... Remember, "Shadow People" will ask you to pay for something you can't see... ..but you're smarter than that though, right? you are :) I still have people who have beern told that they must buy internally flawless, or risk imperfections that will bother then for life. Fact is that for most people a finer cut "VS" grade is vastly beyond eyeclean, and sort of like buzz lightyear would say "The VVS range is in perfection and clarity next to infinity and beyond"... Flawless and perfect for that perfect gal, I can't knock that of course... It's just that to upsell you that at the VVS range you are going to see a difference is not common sense. can thank me later, right now read on...

In practical terms an extremely finely cut VS2 is both beautiful and apparantly perfectly eye clean to most, for the extra practical insurance stay in the "VS-1" range if you can. You can use the money you save not buying a "VVS" now and either get a larger diamond, better color (or even a box of chocolates for me for helping you save :) Remember that halagon lights can bring out the sparkle in driveway gravel, so be smart and buy quality, and always carefully check the numbers on each line item of the certificates and lab reports! They are critical to both the beauty and the value, remember in diamonds "cheaper is not usually better", unless all the line items of the lab report are the same. Comparing a diamond with a great cut against a poorly cut stone, of the same clarity color and weight, is like comparing apples to oranges... On the trade-up you will be effected by how well that you did right now, so buying a more desirable cut now is a more liquid trade-up later. Buy a big ugly diamond and the term "Diamonds are forever" stands as having meaning for you. You can loose 25% of the value of a diamond from poor cuts!

Without the optics being right the stone is dead and discounted. Remember a diamond's only job is beauty, and I'd make a good case that starts to happen in the "G-SI1" ranges with great math of course... :) In the SI-2 range and below starts visual problems which denigrate the beauty of the diamond... The creative "SI3" should be renamed back to "Imperfect" but the creative marketing retailer types love this new "SI3" grade, you will probably hate it... Really watch aspect ratios on fancy cuts, for the oval ideal is (1:1.5), and for the marquise diamond it is (2:1) as long as measured wide... This is a critical measurement, for optically the diamond is effected when squatty or miss-shapen... Remember too that in the emerald cuts that a VVS or VS range is the best, for this is a cut that is very reflective, and the SI range means that there will be activity and that will show more than in the other cuts.

"Extremely poor cuts are significantly discounted", so don't be fooled by the color and clarity alone... While prices will vary greatly, based on differences in markups, diamond grading should not.... Which is why I suggest graded stones by GIA,AGS, EGL, GGL and other gemological institutions. Commonm sense, when you go to trade in the diamond for a larger one the quality and the certificate become an issue, so what you do now matters more than you might appreciate... A strip mall jeweler saying a diamond is for example a "VS1-F" doesn't mean a thing unless there is a certificate. That does not mean locally generated gem lab paper either folks, do not make that mistake.

Unless you have money to burn, it really matters! Benchmark certificates by unbiased gemological institutions are always the way to go when buying or comparing value... Their lab certificates provide facts and numbers you can use to compare relative values and similar stones.You can save and maximize your diamond's value and beauty.
