About this 0.5ct lab-grown oval diamond

This 0.5ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407915170 or 407915170. Listed at 13 retailers as of November 1, 2026, with prices from $533 to $2,649, a $2,115 spread on the same certified stone. MOH London lists it at $2,649. 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.
