About this 4.28ct lab-grown oval diamond

This 4.28ct 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 LG574320838 or 574320838. Listed at 15 retailers as of October 31, 2026, with prices from $1,384 to $5,483, a $4,099 spread on the same certified stone. Brilliant Earth lists it at $5,483. 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.
