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 SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407950365 or 407950365. Listed at 11 retailers as of November 1, 2026, with prices from €242 to €1,199, a €958 spread on the same certified stone. MOH London lists it at €1,199. 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.
