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 LG573398321 or 573398321. Listed at 15 retailers as of October 31, 2026, with prices from $1,340 to $10,273, a $8,934 spread on the same certified stone. Brilliant Earth lists it at $10,273. 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.
