About this 1.29ct natural radiant diamond

This 1.29ct natural radiant sits in the one-and-a-quarter to one-and-a-half carat band, graded F 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 1555792779. Listed at 11 retailers as of October 31, 2026, with prices from €2,672 to €5,082, a €2,410 spread on the same certified stone. Helzberg Diamonds lists it at €5,082. 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.
