That is a specific and unique request. A 3-carat Cushion cut with VVS1 clarity is a top-tier investment-grade stone, but the W color puts it into a very niche category. In the GIA grading system, W falls in the "Light Yellow" range (S-Z). This means the stone will have a distinct, warm buttery tint. It is not quite "Fancy Yellow," but it is much more colorful than the "Near Colorless" (G-J) or "Faint Yellow" (K-M) ranges. Color (W): At this size (3 carats), the yellow tint will be quite noticeable. Because cushion cuts are designed with deep pavilions, they tend to "trap" color better than round cuts, likely making it look like a "Fancy Light Yellow." Clarity (VVS1): This is nearly perfect. Even under 10x magnification, it is extremely difficult for a professional grader to see any inclusions. It is essentially eye-clean and "microscope-clean." Shape (Cushion): You’ll want to check if it is a "Cushion Brilliant" (larger flashes of light) or a "Cushion Modified" (the "crushed ice" look). Modified cushions are more common in this color range as they intensify the yellow hue. etting Choice: A stone this "warm" looks stunning in 18k Yellow Gold. The gold prongs will blend with the diamond's tint, making the yellow look intentional and rich. If you set it in Platinum or White Gold, the contrast will make the diamond look more "tinted" or "off-white." Important Information for Buyers: 1.
