About this 1.55ct natural oval diamond

This 1.55ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a top-tier cut grade and certified by IGI 719535496. Listed at 8 retailers as of October 31, 2026, with a relatively tight 22% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
