This 2.57ct lab-grown oval sits in the two to three carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG636469096 or 636469096. Listed at 3 retailers as of October 31, 2026, with prices from £251 to £1,396, a £1,145 spread on the same certified stone. Brilliant Earth lists it at £1,396. 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.
