About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1166717038. Listed at 4 retailers as of October 30, 2026, with prices from HK$10,019 to HK$15,074, a HK$5,055 spread on the same certified stone. 77 Diamonds lists it at HK$15,074. 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.
