Guatemala is another jade commercial origin in addition to the Myanmar. The Guatemalan jade is usually an assemblage of a variety of mineral compositions, and the mineral composition is unique and different from the Myanmar jade. The characteristics of the structures and paragenetic minerals of the purple and gray-green jade from Guatemala were studied by laser Raman spectroscopy analysis.

In the present paper, different-generation hydrothermally grown KTP crystals were tested by the Nicolet 550 type FIR spectrometer with the reflective technique. They were studied on different crystal faces. Since the hydrothermally grown KTP crystal usually grows (100), (011) and (201) crystal faces, these faces were tested in different-generation products, and they were tested by two spectral wave bands, 2 000-4 000 and 400-2 000 cm(-1).

Article Synopsis
- * It finds that, while the synthetic jadeite jade is similar to natural jadeite jade in the FTIR fingerprint region, notable differences appear in the 2,000 - 4,000 cm(-1) range, particularly related to O-H vibrations.
- * The results also reveal that the spectral peaks for the synthetic jadeite jade shift to higher frequencies, indicating it lacks isomorphism of heavy positive ions, while maintaining sharp scattering peaks in Raman spectra consistent with natural jadeite jade.
