This 3.98ct lab-grown oval sits in the three to five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG838621829 or 838621829. Listed at 23 retailers as of October 29, 2026, with prices from $1,105 to $9,546, a $8,440 spread on the same certified stone. Brilliant Earth lists it at $9,546. 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.
