Yellow Diamond crystal (RARE) in conglomerate Obodda Coll.

Item Description

Colored diamonds are highly desirable and rare in the gem world. This is a very rare and old Brazilian specimen of a gemmy, glassy, 3 mm yellow, octahedral diamond crystal nestled amongst conglomerate river pebbles on a cobble from the famous Jequitinhonha valley of Minas Gerais. These alluvial diamonds, deposited into conglomerates over time, are the reason this region of Brazil was named after an old-time diamond rush. Seldom are such specimens, especially colored diamonds, preserved, for obvious reasons. This one, amazingly, has very prominent, poorly sorted pebbles and sandstone resting on a well-rounded, rust-red cobble.This very showy and fine old-timer is mounted on a labeled antique, circular wood base (probably 1800s to early 1900s). The measurements include the circular wooden mount and large pebble. Ex Herb Obodda Collection # 2821. Value of such a rarity and antiquity should be around $2500-3000
