This 0.55ct lab-grown radiant sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG592351621 or 592351621. Listed at 14 retailers as of October 28, 2026, with prices from $216 to $2,021, a $1,805 spread on the same certified stone. MOH London lists it at $2,021. 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.
