About this 3.94ct lab-grown oval diamond

This 3.94ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG784690994 or 784690994. Listed at 6 retailers as of October 31, 2026, with a 493% 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.
