About this 1.51ct lab-grown cushion diamond

This 1.51ct lab-grown cushion 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 LG407985767 or 407985767. Listed at 3 retailers as of October 26, 2026, with prices from HK$3,201 to HK$8,550, a HK$5,348 spread on the same certified stone. MOH London lists it at HK$8,550. 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.
