About this 1.22ct lab-grown oval diamond

This 1.22ct lab-grown oval sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG611391288 or 611391288. Listed at 18 retailers as of October 28, 2026, with prices from £263 to £1,030, a £767 spread on the same certified stone. Reve Diamonds lists it at £1,030. 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.
