About this 0.78ct lab-grown oval diamond

This 0.78ct lab-grown oval sits in the just-under-one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825656551 or 825656551. Listed at 17 retailers as of November 3, 2026, with prices from $428 to $2,009, a $1,582 spread on the same certified stone. Reve Diamonds lists it at $2,009. 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.
