About this 0.9ct lab-grown oval diamond

This 0.9ct lab-grown oval sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG407930373 or 407930373. Listed at 13 retailers as of October 27, 2026, with prices from £481 to £2,815, a £2,335 spread on the same certified stone. MOH London lists it at £2,815. 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.
