About this 1.06ct natural radiant diamond

This 1.06ct natural radiant sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 16135252. Listed at 5 retailers as of October 30, 2026, with prices from $3,383 to $5,173, a $1,791 spread on the same certified stone. 77 Diamonds lists it at $5,173. 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.
