About this 0.75ct natural heart diamond

This 0.75ct natural heart sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by HRD 170003089973. Listed at 2 retailers as of November 2, 2026, with prices from £1,164 to £1,380, a £216 spread on the same certified stone. 77 Diamonds lists it at £1,380. 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.
