About this 1.58ct natural cushion diamond

This 1.58ct natural cushion sits in the one-and-a-half to two 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 6555097162. Listed at 19 retailers as of November 1, 2026, with prices from HK$25,409 to HK$54,307, a HK$28,898 spread on the same certified stone. MOH London lists it at HK$54,307. 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.
