Looking for a color that POPS?🍾
5.06ct GIA FANCY VIVID YELLOW VVS2 Treated YELLOW Radiant 💛 only $24999 while it lasts! This is the yellow diamond you’ve been looking for.

Diamonds naturally come in a wide range of colors, but can be permanently color treated (will not fade, not a coating, the color is now inside the stone). Even your blue denim fades over time but color treated diamonds don’t!

This would be 80k if the color was natural. Get the same LOOK for less. 9.9x9.5mm 61 depth!! Looks like a 6ct. No Fluorescence. Even more impressive in person. 👏 👏 👏
