About this 2.51ct natural heart diamond

This 2.51ct natural heart 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 2526909324. Listed at 14 retailers as of November 4, 2026, with prices from HK$103,030 to HK$175,749, a HK$72,718 spread on the same certified stone. MOH London lists it at HK$175,749. 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.
