About this 1.55ct lab-grown radiant diamond

This 1.55ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2474703427. Listed at 8 retailers as of October 26, 2026, with prices from $587 to $1,839, a $1,252 spread on the same certified stone. MOH London lists it at $1,839. 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.
