About this 1.28ct natural cushion diamond

This 1.28ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded L colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2151155421. Listed at a single retailer as of November 5, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically.
