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 LG622478464 or 622478464. Listed at 20 retailers as of October 29, 2026, with prices from $331 to $3,120, a $2,789 spread on the same certified stone. Brilliant Earth lists it at $3,120. 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.
