About this 0.51ct lab-grown heart diamond

This 0.51ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG839630302 or 839630302. Listed at 6 retailers as of October 26, 2026, with prices from $347 to $1,207, a $860 spread on the same certified stone. MOH London lists it at $1,207. 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.
