About this 0.48ct natural heart diamond

This 0.48ct natural heart sits in the sub-half-carat band, graded G 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 5566285838. Listed at 2 retailers as of November 2, 2026, with prices from £323 to £404, a £81 spread on the same certified stone. 77 Diamonds lists it at £404. 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.
