About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1543693662. Listed at 7 retailers as of November 5, 2026, with prices from HK$25,646 to HK$30,910, a HK$5,264 spread on the same certified stone. Blue Nile lists it at HK$30,910. 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.
