About this 0.51ct lab-grown heart diamond

This 0.51ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and VVS2 clarity (very-very-slightly-included) and certified by IGI LG841637689 or 841637689. Listed at 7 retailers as of November 1, 2026, with prices from $520 to $1,390, a $870 spread on the same certified stone. MOH London lists it at $1,390. 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.
