About this 1.07ct lab-grown oval diamond

This 1.07ct lab-grown oval sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless) and certified by IGI LG778688498 or 778688498. Listed at 23 retailers as of October 24, 2026, with prices from $284 to $2,760, a $2,476 spread on the same certified stone. Brilliant Earth lists it at $2,760. 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.
