About this 1.2ct lab-grown cushion diamond

This 1.2ct lab-grown cushion sits in the classic one-carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 2 retailers as of November 5, 2026, with prices from $1,505 to $1,758, a $254 spread on the same certified stone. Blue Nile lists it at $1,758. 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.
