This 1.91ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG841678154 or 841678154. Listed at 15 retailers as of October 31, 2026, with prices from $834 to $5,114, a $4,280 spread on the same certified stone. Do Amore Diamonds lists it at $5,114. 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.
