About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG512240900 or 512240900. Listed at 6 retailers as of October 29, 2026, with prices from €244 to €1,117, a €873 spread on the same certified stone. MOH London lists it at €1,117. 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.
