About this 1.3ct natural cushion diamond

This 1.3ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5536923851. Listed at 8 retailers as of November 6, 2026, with prices from HK$16,247 to HK$30,958, a HK$14,711 spread on the same certified stone. With Clarity lists it at HK$30,958. 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.
