About this 0.53ct natural heart diamond

This 0.53ct natural heart sits in the half to three-quarter 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 6545478334. Listed at 5 retailers as of October 31, 2026, with prices from £319 to £428, a £109 spread on the same certified stone. Blue Nile lists it at £428. 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.
