This 0.59ct lab-grown oval sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818671991 or 818671991. Listed at 5 retailers as of October 29, 2026, with prices from $469 to $1,901, a $1,432 spread on the same certified stone. MOH London lists it at $1,901. 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.
