About this 4.01ct lab-grown oval diamond

This 4.01ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5221299400. Listed at 10 retailers as of October 27, 2026, with prices from £1,108 to £4,265, a £3,158 spread on the same certified stone. MOH London lists it at £4,265. 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.
