About this 1.4ct natural round diamond

This 1.4ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded M colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by GIA 3535807452. Listed at 9 retailers as of November 5, 2026, with a relatively tight 25% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
