About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-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 2245004878. Listed at 12 retailers as of November 3, 2026, with prices from HK$18,597 to HK$34,570, a HK$15,973 spread on the same certified stone. Helzberg Diamonds lists it at HK$34,570. 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.
