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 November 2, 2026, with prices from $11,446 to $19,815, a $8,370 spread on the same certified stone. NZ Jewellers lists it at $19,815.
