This 4.01ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG574338629 or 574338629. Listed at 12 retailers as of November 6, 2026, with prices from $749 to $4,618, a $3,869 spread on the same certified stone. Brilliant Earth lists it at $4,618. 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.
