This 1.68ct lab-grown round 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 LG837647010 or 837647010. Listed at 9 retailers as of October 29, 2026, with prices from $1,514 to $4,030, a $2,516 spread on the same certified stone. MOH London lists it at $4,030. 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.
