About this 2.51ct natural cushion diamond

This 2.51ct natural cushion sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1549392997. Listed at 6 retailers as of November 2, 2026, with prices from HK$146,686 to HK$175,753, a HK$29,067 spread on the same certified stone. Jared lists it at HK$175,753. 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.
