This 1.53ct 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 very-good cut grade and certified by IGI LG733599237 or 733599237. Listed at 20 retailers as of November 4, 2026, with prices from $938 to $6,343, a $5,405 spread on the same certified stone. Brilliant Earth lists it at $6,343. 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.
