About this 0.51ct lab-grown round diamond

This 0.51ct lab-grown round sits in the half to three-quarter carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LGS3A59597 or S3A59597. Listed at 2 retailers as of October 30, 2026, with prices from €505 to €882, a €376 spread on the same certified stone. Yorxs lists it at €882. 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.
