About this 1.51ct natural oval diamond

This 1.51ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 801639230. Listed at 17 retailers as of October 30, 2026, with prices from HK$29,304 to HK$59,784, a HK$30,481 spread on the same certified stone. NZ Jewellers lists it at HK$59,784. 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.
