About this 2.5ct natural cushion diamond

This 2.5ct natural cushion sits in the two to three carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552015798. Listed at 10 retailers as of October 31, 2026, with prices from HK$129,713 to HK$167,267, a HK$37,555 spread on the same certified stone. 77 Diamonds lists it at HK$167,267. 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.
