This 0.52ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816662420 or 816662420. Listed at 13 retailers as of November 3, 2026, with prices from $326 to $1,639, a $1,313 spread on the same certified stone. Reve Diamonds lists it at $1,639. 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.
