About this 0.8ct natural cushion diamond

This 0.8ct 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 2131518480. Listed at 9 retailers as of October 28, 2026, with prices from HK$13,284 to HK$17,497, a HK$4,214 spread on the same certified stone. Jared lists it at HK$17,497. 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.
