About this 2.51ct natural round diamond

This 2.51ct natural round sits in the two to three carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by GIA 1555116981. Listed at 13 retailers as of November 5, 2026, with prices from $10,660 to $20,455, a $9,794 spread on the same certified stone. NZ Jewellers lists it at $20,455.
