This 1.03ct lab-grown asscher sits in the classic one-carat band, graded F colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658608 or 818658608. Listed at 19 retailers as of October 31, 2026, with prices from $314 to $1,950, a $1,636 spread on the same certified stone. Brilliant Earth lists it at $1,950. 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.
