About this 0.57ct lab-grown oval diamond

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 LG816662355 or 816662355. Listed at 19 retailers as of October 29, 2026, with prices from $254 to $1,441, a $1,187 spread on the same certified stone. Diamond Exchange Canada lists it at $1,441. 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.
