About this 1.4ct natural cushion diamond

This 1.4ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557670551. Listed at 9 retailers as of November 1, 2026, with prices from $4,592 to $8,650, a $4,058 spread on the same certified stone. With Clarity lists it at $8,650. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
