About this 1.7ct natural cushion diamond

This 1.7ct natural cushion sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and I1 clarity (included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6391576750. Listed at 8 retailers as of October 28, 2026, with prices from HK$27,225 to HK$39,386, a HK$12,161 spread on the same certified stone. Yorxs lists it at HK$39,386. 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.
