This 1.27ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840634915 or 840634915. Listed at 16 retailers as of November 4, 2026, with prices from $420 to $2,880, a $2,460 spread on the same certified stone. Helzberg Diamonds lists it at $2,880. 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.
