About this 3.5ct natural radiant diamond

This 3.5ct natural radiant sits in the three to five carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551518698. Listed at 3 retailers as of October 31, 2026, with prices from $47,776 to $55,798, a $8,022 spread on the same certified stone. Blue Nile lists it at $55,798. 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.
