About this 0.77ct lab-grown oval diamond

This 0.77ct lab-grown oval sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG425073396 or 425073396. Listed at 4 retailers as of October 26, 2026, with prices from $825 to $1,650, a $825 spread on the same certified stone. Jared lists it at $1,650. 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.
