About this 0.34ct lab-grown round diamond

This 0.34ct lab-grown round sits in the sub-half-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG459129416 or 459129416. Listed at 10 retailers as of October 29, 2026, with prices from $151 to $881, a $730 spread on the same certified stone. MOH London lists it at $881. 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.
