About this 0.55ct natural radiant diamond

This 0.55ct natural radiant sits in the half to three-quarter carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2557276981. Listed at 3 retailers as of October 31, 2026, with prices from €480 to €580, a €100 spread on the same certified stone. Michael Trio lists it at €580. 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.
