About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1216442789. Listed at 9 retailers as of October 30, 2026, with prices from HK$81,689 to HK$145,302, a HK$63,613 spread on the same certified stone. NZ Jewellers lists it at HK$145,302. 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.
