About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-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 1559859205. Listed at 13 retailers as of November 4, 2026, with prices from $6,126 to $11,063, a $4,937 spread on the same certified stone. Wholesale Diamonds Direct lists it at $11,063. 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.
