About this 0.59ct natural heart diamond

This 0.59ct natural heart sits in the half to three-quarter carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA. Listed at 3 retailers as of October 31, 2026, with prices from £1,064 to £1,292, a £228 spread on the same certified stone. Blue Nile lists it at £1,292. Flawless clarity in sub-one-carat stones is rarely visible to the naked eye over VS1, so you are paying a meaningful premium for grade rather than appearance.
