This 1.03ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG838645355 or 838645355. Listed at 5 retailers as of November 4, 2026, with prices from $391 to $1,073, a $682 spread on the same certified stone. MOH London lists it at $1,073. 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.
