About this 1ct lab-grown heart diamond

This 1ct lab-grown heart sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG771639660 or 771639660. Listed at 17 retailers as of November 1, 2026, with prices from HK$2,171 to HK$10,790, a HK$8,619 spread on the same certified stone. MOH London lists it at HK$10,790. 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.
