This 0.57ct 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 LG845672426 or 845672426. Listed at 14 retailers as of October 29, 2026, with prices from $447 to $2,043, a $1,596 spread on the same certified stone. Riddles Jewelry lists it at $2,043. 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.
