About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6542765247. Listed at 13 retailers as of October 27, 2026, with prices from HK$34,374 to HK$67,331, a HK$32,958 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$67,331. 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.
