About this 4.15ct lab-grown oval diamond

This 4.15ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG566302199 or 566302199. Listed at 16 retailers as of October 31, 2026, with prices from £571 to £2,761, a £2,190 spread on the same certified stone. Brilliant Earth lists it at £2,761. 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.
