This 3.51ct natural asscher sits in the three to five carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a top-tier cut grade stated by the retailer rather than the lab and certified by GIA 2151621906. Listed at 4 retailers as of October 30, 2026, with prices from £18,354 to £23,175, a £4,821 spread on the same certified stone. 77 Diamonds lists it at £23,175.
