About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6541879645. Listed at 16 retailers as of October 29, 2026, with prices from HK$6,428 to HK$16,501, a HK$10,074 spread on the same certified stone. Flawless Fine Jewelry lists it at HK$16,501. 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.
