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) and certified by IGI LG761556321 or 761556321. Listed at 21 retailers as of November 1, 2026, with prices from $495 to $1,490, a $995 spread on the same certified stone. Brilliant Earth lists it at $1,490. 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.
