About this 0.45ct lab-grown round diamond

This 0.45ct lab-grown round sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LGS3A75789 or S3A75789. Listed at 2 retailers as of November 6, 2026, with prices from $795 to $1,466, a $671 spread on the same certified stone. Yorxs lists it at $1,466. 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.
