About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816658334 or 816658334. Listed at 10 retailers as of October 31, 2026, with a 395% 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.
