About this 1.5ct natural radiant diamond

This 1.5ct natural radiant sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2504957545. Listed at 6 retailers as of November 4, 2026, with prices from HK$18,144 to HK$27,497, a HK$9,353 spread on the same certified stone. 77 Diamonds lists it at HK$27,497. 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.
