About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG803661987 or 803661987. Listed at 9 retailers as of October 26, 2026, with prices from $250 to $1,501, a $1,251 spread on the same certified stone. MOH London lists it at $1,501. 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.
