This 1.09ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG850690105 or 850690105. Listed at 7 retailers as of November 1, 2026, with prices from $335 to $1,364, a $1,029 spread on the same certified stone. MOH London lists it at $1,364. 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.
