This 0.55ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG744523866 or 744523866. Listed at 4 retailers as of October 26, 2026, with prices from $205 to $1,175, a $970 spread on the same certified stone. MOH London lists it at $1,175. 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.
