About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG835646887 or 835646887. Listed at 20 retailers as of November 3, 2026, with prices from $254 to $1,865, a $1,611 spread on the same certified stone. Brilliant Earth lists it at $1,865. 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.
