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. Of course, 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.

It's a Square Radiant Cut Diamond- with some very nice corners.

This gives the diamond it's personality, IMO.

I  love the cut.

 The cut of this diamond is beautiful. Extremely appealing.

It's a lovely "warm white" color. If you're looking for a D, this one likely won't please you.

But we're sold hundreds of K-L colored emerald cuts to satisfied owners. many people actually love the slight tint.
