About this 1ct lab-grown oval diamond

This 1ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG851683293 or 851683293. Listed at 14 retailers as of October 31, 2026, with prices from $302 to $1,301, a $999 spread on the same certified stone. Taylor and Hart lists it at $1,301. 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.
