About this 0.51ct natural cushion diamond

This 0.51ct natural cushion sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1519671765. Listed at 11 retailers as of November 4, 2026, with prices from $1,250 to $2,650, a $1,400 spread on the same certified stone. Flawless Fine Jewelry lists it at $2,650. 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.
