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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1215215357. Listed at 11 retailers as of October 28, 2026, with prices from HK$24,594 to HK$36,784, a HK$12,190 spread on the same certified stone. The Diamond Guys lists it at HK$36,784. 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.
