About this 3.03ct lab-grown oval diamond

This 3.03ct 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 LG570365523 or 570365523. Listed at 17 retailers as of November 1, 2026, with prices from $1,278 to $4,230, a $2,952 spread on the same certified stone. Brilliant Earth lists it at $4,230. 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.
