About this 1.54ct lab-grown radiant diamond

This 1.54ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG526270546 or 526270546. Listed at a single retailer as of October 29, 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.
