About this 5.09ct lab-grown oval diamond

This 5.09ct lab-grown oval sits in the over five carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839639565 or 839639565. Listed at 22 retailers as of October 28, 2026, with a 326% 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.
