About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-one-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 1555570798. Listed at 4 retailers as of November 6, 2026, with prices from HK$7,728 to HK$9,540, a HK$1,813 spread on the same certified stone. Michael Trio lists it at HK$9,540. 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.
