About this 1.29ct natural cushion diamond

This 1.29ct natural cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded J 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 2386296244. Listed at 23 retailers as of October 31, 2026, with prices from HK$18,888 to HK$41,183, a HK$22,295 spread on the same certified stone. MOH London lists it at HK$41,183. 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.
