About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG598379013 or 598379013. Listed at 6 retailers as of October 29, 2026, with a 586% 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.
