About this 4.03ct lab-grown oval diamond

This 4.03ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG804639265 or 804639265. Listed at 24 retailers as of November 1, 2026, with a 713% spread between the cheapest and most expensive listing. That is exactly the kind of price-discovery gap Carat Hunter was built to surface. 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.
