This 4.12ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG564358585 or 564358585. Listed at 16 retailers as of October 31, 2026, with prices from $1,348 to $6,512, a $5,163 spread on the same certified stone. Brilliant Earth lists it at $6,512. 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.
