About this 1.61ct natural heart diamond

This 1.61ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2534954765. Listed at 4 retailers as of October 28, 2026, with prices from £2,407 to £4,950, a £2,543 spread on the same certified stone. MOH London lists it at £4,950. 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.
