About this 2.51ct natural radiant diamond

This 2.51ct natural radiant sits in the two to three carat band, graded H 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 2536421006. Listed at 5 retailers as of October 26, 2026, with prices from HK$61,377 to HK$105,549, a HK$44,172 spread on the same certified stone. MOH London lists it at HK$105,549. 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.
