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 stated by the retailer rather than the lab and certified by GIA 7466310402. Listed at 14 retailers as of October 30, 2026, with prices from €314 to €2,291, a €1,977 spread on the same certified stone. Do Amore Diamonds lists it at €2,291. 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.
