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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 7431617938. Listed at 12 retailers as of October 28, 2026, with prices from HK$24,453 to HK$36,384, a HK$11,931 spread on the same certified stone. 77 Diamonds lists it at HK$36,384. 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.
