About this 0.91ct natural cushion diamond

This 0.91ct natural cushion sits in the just-under-one-carat band, graded I 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 2198315901. Listed at 11 retailers as of November 2, 2026, with prices from HK$14,782 to HK$22,926, a HK$8,144 spread on the same certified stone. 77 Diamonds lists it at HK$22,926. 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.
