About this 1.28ct natural round diamond

This 1.28ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade and certified by GIA 6531404476. Listed at 16 retailers as of October 26, 2026, with a relatively tight 15% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
