About this 1ct natural round diamond

This 1ct natural round sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 2221820475. Listed at 19 retailers as of October 27, 2026, with prices from $8,190 to $14,179, a $5,989 spread on the same certified stone. NZ Jewellers lists it at $14,179. 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.
