This 1.65ct lab-grown cushion sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG541284434 or 541284434. Listed at 17 retailers as of November 1, 2026, with prices from $633 to $5,030, a $4,397 spread on the same certified stone. Do Amore Diamonds lists it at $5,030. 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.
