About this 0.7ct lab-grown oval diamond

This 0.7ct 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 LG445037748 or 445037748. Listed at 11 retailers as of October 31, 2026, with prices from £336 to £1,533, a £1,197 spread on the same certified stone. MOH London lists it at £1,533. 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.
