About this 1.18ct natural heart diamond

This 1.18ct natural heart sits in the classic 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 HRD 180000166540. Listed at 3 retailers as of November 5, 2026, with prices from £2,041 to £2,502, a £461 spread on the same certified stone. Yorxs lists it at £2,502. 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.
