About this 4.09ct lab-grown oval diamond

This 4.09ct lab-grown oval sits in the three to five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG573381123 or 573381123. Listed at 17 retailers as of October 27, 2026, with prices from $965 to $7,402, a $6,437 spread on the same certified stone. Brilliant Earth lists it at $7,402. 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.
