About this 4.56ct lab-grown oval diamond

This 4.56ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG569325451 or 569325451. Listed at 17 retailers as of October 29, 2026, with prices from £460 to £3,344, a £2,883 spread on the same certified stone. Brilliant Earth lists it at £3,344. 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.
