About this 15.09ct lab-grown oval diamond

This 15.09ct lab-grown oval sits in the over five carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG828648449 or 828648449. Listed at 19 retailers as of November 1, 2026, with a 135% 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.
