About this 1.51ct natural heart diamond

This 1.51ct natural heart sits in the one-and-a-half to two carat band, graded J 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 7308781385. Listed at 14 retailers as of November 2, 2026, with prices from HK$25,879 to HK$55,053, a HK$29,174 spread on the same certified stone. MOH London lists it at HK$55,053. 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.
