This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG819639876 or 819639876. Listed at 4 retailers as of October 30, 2026, with prices from $2,450 to $3,336, a $885 spread on the same certified stone. Zales lists it at $3,336. 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.
