About this 1.51ct natural radiant diamond

This 1.51ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 6382782765. Listed at 5 retailers as of November 6, 2026, with prices from HK$16,310 to HK$24,241, a HK$7,931 spread on the same certified stone. 77 Diamonds lists it at HK$24,241. 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.
