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 $46,715 to $54,751, a $8,037 spread on the same certified stone. Blue Nile lists it at $54,751. 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.
