About this 5.62ct lab-grown oval diamond

This 5.62ct lab-grown oval sits in the over five carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG698577479 or 698577479. Listed at 16 retailers as of October 28, 2026, with a 433% 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.
