About this 0.3ct natural heart diamond

This 0.3ct natural heart sits in the sub-half-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7558953290. Listed at 6 retailers as of October 27, 2026, with prices from £187 to £286, a £100 spread on the same certified stone. Wholesale Diamonds Direct lists it at £286. 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.
