About this 2.51ct natural cushion diamond

This 2.51ct 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 7558789813. Listed at 10 retailers as of November 1, 2026, with prices from HK$134,694 to HK$232,383, a HK$97,689 spread on the same certified stone. MOH London lists it at HK$232,383. 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.
