About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1429827791. Listed at 13 retailers as of October 29, 2026, with prices from HK$7,231 to HK$18,166, a HK$10,935 spread on the same certified stone. MOH London lists it at HK$18,166. 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.
