This 3.56ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG585304322 or 585304322. Listed at 17 retailers as of October 30, 2026, with prices from £656 to £2,694, a £2,038 spread on the same certified stone. Brilliant Earth lists it at £2,694. 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.
