About this 1ct lab-grown round diamond
This 1ct lab-grown round sits in the classic one-carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by IGI LGS3G58417 or S3G58417. Listed at a single retailer as of October 30, 2026. If it later appears at another store, Carat Hunter will surface the price comparison automatically. 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.
