About this 1.51ct natural radiant diamond

This 1.51ct natural radiant sits in the one-and-a-half to two carat band, graded K 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 3545914037. Listed at 12 retailers as of November 5, 2026, with prices from HK$18,128 to HK$32,736, a HK$14,608 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$32,736. 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.
