“Water ripple” turquoise is a kind of natural turquoise with water ripple pattern on its appearance, which is rare in production but popular among consumers. Previous studies on turquoise are rich, but less on “water ripple”. In this paper, a turquoise sample with the light blue-white substrate and blue-green “water ripple” stripe was tested by micro laser Raman spectrometer, micro infrared spectrometer, micro X-ray diffraction, laser ablation system inductively coupled plasma mass spectrometer (LA-ICP-MS), scanning electron microscope and micro ultraviolet-visible near-infrared spectrometer. The results show that the main minerals in the stripe and non-stripeboth are turquoise, and show the infrared spectra and Raman spectra of turquoise; The chemical composition of the stripe is different from that of the non-stripe. The content of Al₂O₃, SiO₂, MgO, V, Co, Ni, U, Y, Mo and Cd in the stripe is higher than that of non-stripe, while the content of P₂O₅, CuO, K₂O and Na₂O in non-stripe is higher than that of the stripe; The results of SEM microtopography show that most of the crystals in the stripe area are thick plate, large crystal particles, closely arrangement and almost invisible pores, while the crystals in the non-stripe area are mostly columnar with different sizes, fragmentary, disorderly arrangement and visible pores; The results of X-ray diffraction show that the crystallinity in the stripe is higher than that in the non-stripe; The results of micro UV-vis-NIR show that the absorption peaks are at 426 and 660 nm, and the chromogenic ions are Fe³⁺ and Cu²⁺. The spectral characteristics of “water ripples” turquoise sample show that the color difference between the stripes and the non-stripes is not related to the chromogenic ions, while the color and transparency difference is mainly related to the crystallinity and density of turquoise. The change of the crystallinity in “water ripple” turquoise indicates the instability of the formation environment of turquoise, and the periodic change of crystallinity indicates that the surrounding environment of turquoise formation has the regularity. It provides data support for the study of color origin and the metallogenic environment of turquoise.
