About this 0.59ct natural radiant diamond

This 0.59ct natural radiant sits in the half to three-quarter carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556015868. Listed at 3 retailers as of November 6, 2026, with prices from £369 to £446, a £77 spread on the same certified stone. Michael Trio lists it at £446. 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.
