This 1.23ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831682826 or 831682826. Listed at 6 retailers as of October 25, 2026, with prices from $424 to $1,476, a $1,051 spread on the same certified stone. MOH London lists it at $1,476. 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.
