About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded G 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 6565102550. Listed at 15 retailers as of October 29, 2026, with prices from HK$40,706 to HK$79,846, a HK$39,140 spread on the same certified stone. MOH London lists it at HK$79,846. 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.
