About this 0.54ct natural radiant diamond

This 0.54ct natural radiant sits in the half to three-quarter carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2186816347. Listed at 17 retailers as of October 30, 2026, with prices from €456 to €1,688, a €1,231 spread on the same certified stone. NZ Jewellers lists it at €1,688. 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.
