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 standard cut grade stated by the retailer rather than the lab and certified by GIA 1435576385. Listed at 22 retailers as of October 28, 2026, with prices from HK$82,619 to HK$155,761, a HK$73,141 spread on the same certified stone. NZ Jewellers lists it at HK$155,761. 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.
