This 1.51ct natural round sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by GIA 2507160588. Listed at 19 retailers as of November 5, 2026, with prices from HK$70,419 to HK$176,905, a HK$106,486 spread on the same certified stone. Diamond Quarter lists it at HK$176,905. 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.
