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 G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7538873746. Listed at 19 retailers as of November 6, 2026, with prices from HK$21,302 to HK$45,149, a HK$23,847 spread on the same certified stone. MOH London lists it at HK$45,149. 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.
