About this 0.31ct lab-grown round diamond

This 0.31ct lab-grown round sits in the sub-half-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG459129369 or 459129369. Listed at 11 retailers as of October 25, 2026, with prices from $170 to $987, a $817 spread on the same certified stone. MOH London lists it at $987. 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.
