This 3.97ct lab-grown oval sits in the three to five carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG829610832 or 829610832. Listed at 22 retailers as of October 27, 2026, with prices from $1,027 to $8,942, a $7,915 spread on the same certified stone. Brilliant Earth lists it at $8,942. 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.
