About this 1.5ct natural round diamond

This 1.5ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 2428351005. Listed at 18 retailers as of October 30, 2026, with prices from HK$31,533 to HK$71,710, a HK$40,176 spread on the same certified stone. NZ Jewellers lists it at HK$71,710. 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.
