Abstract

HIGHLIGHTS
(1) The relationship of Fe²⁺ and Fe³⁺ contents with hue in Qinghai nephrite indicated the effect on color-inducing.

(2) The relationship between ICP-MS data and tone was used to illustrate the transitional metal elements related to color.

(3) EPR data indicated that Cr of the chromogenic element in azure-green Qinghai nephrite was Cr³⁺ and the crystal position was M₁ or M₃.

(4) Ti³⁺ EPR spectral line was not found at low temperature liquid state, indicating that Ti element related to color formation was Ti⁴⁺.

ABSTRACT

BACKGROUNDColor is the important manifestation of nephrite value. Qinghai nephrite has different colors, but there is a lack of research on coloration. In recent years, the study on the coloration of nephrite in Qinghai mainly focused on azure-green and blue-violet, and it was considered that Cr³⁺ and Mn²⁺ were respective coloration elements of azure-green and blue-violet. The color of Qinghai nephrite is not a simple color, such as white-green, azure-green, and blue-violet. Therefore, Qinghai nephrite should contain a variety of color-causing elements.
OBJECTIVESTo reveal the color-causing elements of eight colors of nephrite from Qinghai based on the relationship between analysis data and hue changes.
METHODSX-ray Fluorescence Spectrometry (XRF), Chemical Titration, Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and Electron Paramagnetic Resonance Spectroscopy (EPR) were used to study the color-causing elements of nephrite.
RESULTSThe color-causing element of white Qinghai nephrite was Fe³⁺. The color-causing elements of white-green and azure-green Qinghai nephrite were Fe²⁺ and Fe³⁺, respectively. The chromogenic elements of green Qinghai nephrite were Fe²⁺, Fe³⁺ and Mn in high valence. The color-causing elements of azure-green Qinghai nephrite were Fe²⁺, Fe³⁺ and Cr³⁺. The chromogenic elements of yellow and brown Qinghai nephrite were Fe³⁺ and high-valence Mn. Fe³⁺ and Ti⁴⁺ were the color-causing elements of blue-purple Qinghai nephrite.
CONCLUSIONSThis study determined the color-causing elements of different colors of Qinghai nephrite, which provided a theoretical basis for the study of the coloration mechanism of Qinghai nephrite.
