About this 1.15ct lab-grown radiant diamond

This 1.15ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included) and certified by IGI LG639486565 or 639486565. Listed at a single retailer as of November 5, 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.
