About this 0.3ct lab-grown round diamond

This 0.3ct lab-grown round sits in the sub-half-carat band, graded J colour (near-colourless) and VVS2 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LGF1R29729 or F1R29729. Listed at 4 retailers as of October 28, 2026, with a relatively tight 23% spread, which is unusual at this carat range and suggests competitive pricing across the listings. 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.
