About this 1ct natural round diamond

This 1ct natural round sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by GIA 1337283683. Listed at 22 retailers as of November 4, 2026, with prices from HK$17,871 to HK$49,260, a HK$31,389 spread on the same certified stone. NZ Jewellers lists it at HK$49,260.
