About this 1.61ct natural radiant diamond

This 1.61ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3145597325. Listed at 6 retailers as of October 31, 2026, with prices from $10,193 to $13,515, a $3,322 spread on the same certified stone. 77 Diamonds lists it at $13,515. 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.
