No reserve price - 1 pcs Diamond (Natural) - 0.40 ct - Round - J - SI2 - Gemological Institute of America (GIA)

This natural round diamond weighs 0.40 carats with a J color and SI2 clarity grade, certified by the Gemological Institute of America (GIA). The round brilliant cut is the most popular diamond shape due to its optimized brilliance and fire, achieved through precise facet arrangements. A J color grade indicates near-colorless quality but with a slightly warmer tint that can be visible when compared side-by-side with higher color grades, though still generally attractive when mounted. The SI2 clarity grade suggests inclusions that may be noticeable under magnification and sometimes to the naked eye, influencing value but not necessarily beauty. GIA certification is widely recognized for independent and accurate verification of diamond quality. Smaller carat diamonds like this are often chosen for delicate jewelry pieces or as accent stones in multi-stone settings.
