About this 1.23ct natural heart diamond

This 1.23ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1489099578. Listed at 6 retailers as of November 4, 2026, with prices from £4,113 to £6,253, a £2,140 spread on the same certified stone. MOH London lists it at £6,253. 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.
