Now that you read about SI Clarity, lets see what VS will do...
VS Clarity
VS will knock your socks off! VS is crisp and clean and simply breathtaking. VS Clarity Diamonds have very small inclusions in them that are pretty difficult to spot under magnification. I love VS Clarity! They're stunning and full of sparkle. You'll never regret buying such a clean stone.
One step higher up the Clarity Chart is VVS! (That rating is V V S, not WS like the font makes it look like!) VVS Clarity Diamonds are quite rare and expensive. But they are almost perfect! Unless you've got tons of dough or just want the best that money can buy, I would pass these up. To the naked eye you won't really see any great visible differences between a VVS Clarity Diamond and a VS Diamond. The only difference is under the scope with tiny, little, microscopic imperfections. Although, not perfect, most people consider these stones to be. If you have money to burn, I would suggest you spend it more wisely and invest in a better Color instead! And speaking of Color...
4) Know what Color you Want
There are only 2 Categories of Color that I would recommend: Colorless and Near Colorless! (White vs Off-White)
My Favorite Color is E or F Colored Diamonds hands down. (Read: Best Diamond Color to Buy!) I love Diamonds that have no color! (Colorless) The Colorless range is D-E-F. D is just about impossible to find. And if you can find it, it'll be insanely priced. Buy an E or F Color if you can.
Colorless Diamonds are so white and bright you'll see the sparkles across the room. They look like they have ten times the amount of brilliance and sparkle of a normal Diamond. They are stunning! I love showing Colorless Diamonds because most people have never seen them. The mall usually only carries lower Color ratings like I-J-K Color! Ouch!
G - H Diamond Color is all right
Nothing wrong with them. Some people can't tell the difference between a White Diamond and an Off-White Diamond. Most people don't notice Color in a Diamond until it actually looks Yellow! And trust me, you don't want a Yellow Diamond! A Yellow tinted Diamond looks dirty and old and it'll rob your Diamond of beauty. Colorless... I'm telling you Colorless is the way to go! Compare Colorless to Near Colorless Diamonds and you'll see how much more sparkle and life you get out of the Diamond. Buy Colorless, you won't regret it!
5) Know what Carat Size you Want
If she says she wants a 1.00 Carat Diamond, get her one! (She'll be sad and blue the rest of her life if you don't.) Plus you'll always be saying to yourself, "I wish I would have bought her that bigger Diamond!" It'll happen, trust me. If you don't know what Diamond Size to buy her and she hasn't dropped you any hints, then I would buy her the biggest Carat Weight that you can afford. But only do that AFTER deciding what Color and Clarity to purchase first!
A Half Carat (.50 Points) is okay. It's cute and small, but it screams cheap and broke. 3/4 Carat (.75 Points) is better. It looks big. It'll have plenty of brilliance and sparkle. You can't go wrong with a 3/4 Carat.
If you Want my Advice:
Buy her a 1.00 Carat Diamond! The ultimate is 1.00 Carat or bigger! I don't know of any woman who doesn't at least want One Full Carat! (Read: Understanding Carats and Points!)
6) Learn about Cut
The Cut is the toughest topic of the 4 C's to comprehend. There's just so much to understand about Cut, it's overwhelming! People try to wrap their heads around it, but the Cut is always confusing. The Cut deals with Angles, Percentages, Millimeter Size, Crown Facets, Culets... BLAH! Where do you begin? You begin step by step! Begin with the most important topics: Measurements and Percentages! I'll try to keep this simple...
A One Carat Diamond should be close in measurements to 6.5 MM Wide. That's from one edge of the stone to the other. The Depth of the Diamond should be around 3.97 MM Deep. That's measured from the flat top of the Diamond to the bottom of the Diamond's Point. (Or the Culet!)
You can quickly see on the Certificate the Diamond's Measurements to compare these too. No Diamond in the World will ever be dead on, but you can get close and that's what matters. If your MM Size is too wide or too deep, you'll lose light and sparkle. Your Diamond will actually look lifeless!
The beauty of a Diamond is it's brilliance. A Diamond with a good MM Size will help your Diamond come to life.
