This 4.12ct 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 LG547268657 or 547268657. Listed at 18 retailers as of October 29, 2026, with prices from £384 to £3,403, a £3,020 spread on the same certified stone. Do Amore Diamonds lists it at £3,403. 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.
