About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2566503696. Listed at 9 retailers as of November 2, 2026, with prices from HK$142,882 to HK$235,273, a HK$92,391 spread on the same certified stone. MOH London lists it at HK$235,273. 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.
