About this 4ct lab-grown oval diamond

This 4ct lab-grown oval sits in the three to five carat band, graded F colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG786666386 or 786666386. Listed at 15 retailers as of October 27, 2026, with a 788% 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.
