About this 0.83ct natural heart diamond

This 0.83ct natural heart sits in the just-under-one-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 1288300786. Listed at 2 retailers as of November 5, 2026, with prices from £1,667 to £1,998, a £331 spread on the same certified stone. Yorxs lists it at £1,998. 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.
