About this 4.01ct lab-grown oval diamond

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 $604 to $3,726, a $3,122 spread on the same certified stone. Brilliant Earth lists it at $3,726. 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.
