About this 4.58ct lab-grown oval diamond

This 4.58ct lab-grown oval sits in the three to five carat band, graded I colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG571378842 or 571378842. Listed at 13 retailers as of October 29, 2026, with a 290% 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.
