About this 1.74ct lab-grown radiant diamond

This 1.74ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1533710924. Listed at 19 retailers as of October 30, 2026, with prices from £1,038 to £4,695, a £3,656 spread on the same certified stone. Taylor and Hart lists it at £4,695. 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.
