About this 0.5ct lab-grown round diamond

This 0.5ct lab-grown round sits in the half to three-quarter carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG341864279 or 341864279. Listed at 2 retailers as of October 31, 2026, with prices from $415 to $586, a $170 spread on the same certified stone. Brilliant Earth lists it at $586. 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.
