About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG763668449 or 763668449. Listed at 15 retailers as of November 1, 2026, with prices from $183 to $1,059, a $876 spread on the same certified stone. MOH London lists it at $1,059. 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.
