About this 1.01ct lab-grown round diamond

This 1.01ct lab-grown round sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 11780507. Listed at 2 retailers as of October 30, 2026, with a relatively tight 3% 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.
