Spectroscopic and microscopic characterizations of color lamellae in natural pink diamonds
Abstract
Nineteen natural, untreated, type IaAB pink diamonds from various localities were studied. They display microscopic (∼1μm thick) pink lamellae along {111} in an otherwise colorless diamond. This coloration concentrated in lamellae is commonly referred to as “graining”. The diamonds were examined using high spatial resolution spectroscopic methods and transmission electron microscopy. TEM revealed that a pink lamella consists of a cluster of …
