About this 0.45ct natural radiant diamond

This 0.45ct natural radiant sits in the sub-half-carat band, graded I 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 6127845164. Listed at 8 retailers as of October 28, 2026, with prices from HK$5,335 to HK$10,911, a HK$5,576 spread on the same certified stone. MOH London lists it at HK$10,911. 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.
