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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6531233461. Listed at 9 retailers as of October 31, 2026, with prices from HK$130,042 to HK$176,542, a HK$46,499 spread on the same certified stone. GemTrove lists it at HK$176,542. 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.
