About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407915436 or 407915436. Listed at 12 retailers as of November 1, 2026, with prices from $587 to $2,914, a $2,327 spread on the same certified stone. MOH London lists it at $2,914. 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.
