This 3.66ct 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 LG561254024 or 561254024. Listed at 16 retailers as of November 1, 2026, with prices from £369 to £3,276, a £2,908 spread on the same certified stone. Do Amore Diamonds lists it at £3,276. 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.
