About this 0.51ct lab-grown oval diamond

This 0.51ct lab-grown oval sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG414063227 or 414063227. Listed at 11 retailers as of November 1, 2026, with prices from $486 to $2,420, a $1,934 spread on the same certified stone. MOH London lists it at $2,420. 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.
