What is S-T color?

It's a good question. I'd place odds that 95% of the people in the jewelry business don't know what S-T color represents.

An S-T color is a lovely light yellow diamond. Sometimes it picks up a lot of color- while other times the color is more subdued. You can notice this in the photos

QUICK SUMMARY ON COLOR GRADING OF DIAMONDS

GIA starts color grading at D. Somehow A, B and C got left off the table, so D is the whitest of white diamonds. Or more accurately- D is the diamond with the least color, or tint.

After that you go to E- which is basically indistinguishable from a D.

Once you get to F you're still not going to see any color- but compare it to a D, and you might be able to notice a slight difference- if you've a sharp eye.

It goes incrementally down, G, H, I, and J represent the rest of what GIA terms "Colorless, or Near Colorless".

Continuing down the color scale, K shows a slight tint, L a bit more, M and N are really starting to show color.

From there, GIA combines the color grades. O-P, Q-R, S-T ( like this one), U-V, W-X, and finally Y-Z. Next color down is Fancy Light Yellow.

The combined letter grades represent a great value in my opinion.

I never minded a diamond that showed some yellow.

A diamond of any color can have all the beauty of a D, or a Fancy Vivid Yellow- provided we're looking at well cut diamonds.

How does a diamond's color affect it's price?

Statistically, the market places a high value on both color and clarity. When we're talking colorless diamonds, slight differences in color can result in large price differences.

D is waaaay up there in terms of price-as are the deeper yellow colors.

If we had to say- which is the lowest priced color in diamonds with GIA reports? It's probably be the stretch between N, and U-V. Indeed, this diamond is in that group. A lower priced diamond that looks as nice ( to me) as a D color. If you like the photos, you'll love the actual diamond.

As you can see from these photos- the diamond is a delicate light yellow shade. Since the hue is subtle, the color looks different depending on the lighting. But even in the dimmest of light- this diamond will sparkle back at you!

It's a Square Radiant Cut Diamond- with some very nice corners. This gives the diamond a lot of personality, IMO.

Another aspect of great cut ( besides the sparkle ) is how large a diamond looks for it's weight. This diamond scores well on this aspect as well- it's large for a 2.05carat. As you can see in the photo below, the diamond has the look of a "bucket of crushed ice"- tremendous sparkle.

I  love the cut.

We're sold hundreds of K-L-M-N- OP- QR- ST-UV-WX-YZ colored diamonds to satisfied owners. Many people actually love the slight tint. If you love this type of stone, you're not alone.
