About this 5.03ct natural cushion diamond

This 5.03ct natural cushion sits in the over five carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2145971305. Listed at 14 retailers as of October 29, 2026, with prices from HK$695,788 to HK$1,205,509, a HK$509,721 spread on the same certified stone. MOH London lists it at HK$1,205,509. 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.
