About this 1.23ct lab-grown cushion diamond

This 1.23ct lab-grown cushion sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG837681161 or 837681161. Listed at 13 retailers as of October 31, 2026, with prices from $506 to $1,491, a $985 spread on the same certified stone. Reve Diamonds lists it at $1,491. 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.
