This 1.3ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG817678140 or 817678140. Listed at 13 retailers as of October 27, 2026, with prices from $592 to $2,212, a $1,620 spread on the same certified stone. Brilliant Earth lists it at $2,212. 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.
