About this 0.56ct lab-grown oval diamond

This 0.56ct lab-grown oval sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG407941407 or 407941407. Listed at 13 retailers as of October 29, 2026, with prices from £239 to £1,270, a £1,031 spread on the same certified stone. MOH London lists it at £1,270. 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.
