About this 1.5ct natural cushion diamond

This 1.5ct natural cushion sits in the one-and-a-half to two carat band, graded J 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 2507409036. Listed at 9 retailers as of November 6, 2026, with prices from HK$22,658 to HK$31,036, a HK$8,378 spread on the same certified stone. Brilliant Earth lists it at HK$31,036. 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.
