About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-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 2517505981. Listed at 23 retailers as of October 29, 2026, with prices from HK$8,537 to HK$20,109, a HK$11,572 spread on the same certified stone. MOH London lists it at HK$20,109. 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.
