About this 1.51ct natural cushion diamond

This 1.51ct 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 5546312975. Listed at 10 retailers as of November 4, 2026, with prices from HK$27,913 to HK$37,029, a HK$9,116 spread on the same certified stone. Brilliant Earth lists it at HK$37,029. 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.
