About this 1.23ct lab-grown oval diamond

This 1.23ct lab-grown oval sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG817614044 or 817614044. Listed at 6 retailers as of October 29, 2026, with prices from $451 to $1,528, a $1,077 spread on the same certified stone. MOH London lists it at $1,528. 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.
