This 0.55ct lab-grown oval sits in the half to three-quarter carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG838645858 or 838645858. Listed at 8 retailers as of October 29, 2026, with prices from $651 to $1,873, a $1,221 spread on the same certified stone. MOH London lists it at $1,873. 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.
