About this 3.56ct lab-grown oval diamond

This 3.56ct lab-grown oval sits in the three to five carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG674516260 or 674516260. Listed at 11 retailers as of October 30, 2026, with a 429% 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.
