About this 1.51ct natural cushion diamond

This 1.51ct natural cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6421495236. Listed at 12 retailers as of October 28, 2026, with prices from HK$26,200 to HK$39,088, a HK$12,888 spread on the same certified stone. 77 Diamonds lists it at HK$39,088. 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.
