About this 1.78ct natural radiant diamond

This 1.78ct natural radiant sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 14918943. Listed at 3 retailers as of November 1, 2026, with prices from HK$100,883 to HK$144,190, a HK$43,307 spread on the same certified stone. MOH London lists it at HK$144,190. 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.
