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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1265037131. Listed at 22 retailers as of October 28, 2026, with prices from HK$15,285 to HK$39,440, a HK$24,156 spread on the same certified stone. Moon Ocean lists it at HK$39,440. 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.
