About this 2.57ct lab-grown oval diamond

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 31, 2026, with prices from $587 to $5,536, a $4,949 spread on the same certified stone. Brilliant Earth lists it at $5,536. 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.
