ANALYSIS OF MINERALS IN CEMPAKA-MADU GEMSTONE FROM ACEH INDONESIA BY USING XRF

Abstract. Cempaka-madu is a local name for one kind of gemstone from Aceh province in Indonesia. It is so attractive and its color is dark-orange. We have utilized X-Ray Florescent (XRF) to study these cempaka-madu gemstones from Aceh Tengah and Nagan Raya districts in Aceh province. Our results show that the cempaka-madu gemstone from Nagan Raya district contains 84.90% of SiO2, 8.89% of NiO, 5.47% of Fe2O3, and 0.6% of CaO. The mineral contains in cempaka-madu gemstone from Aceh Tengah district is about the same as those from Nagan Raya district. It is found that the oxide compounds contained in the cempaka-madu gemstone is significantly different than that in jadeite, nephrite-actinolite, nephrite-tremolite, serpentine-clinochrysotile, serpentine-antigoride, and vesuvianite. Consequently, we conclude that the cempaka-madu gemstone from Aceh Indonesia cannot be categorized as jade. Keywords: cempaka-madu gemstone, jade, jadeite, nephrite, serpentine, vesuvianit

Analysis of Crystallinity and Physical Properties of the Bio-solar Gemstone

Abstract – Bio-solar is one of the natural gemstones found in the province of Aceh in Indonesia. A recent study suggested that this gemstone could be considered as a vesuvianite type of gemstone. Nevertheless, detail information of this bio-solar gemstone is still unknown. We do not know whether the bio-solar gemstone is crystalline or amorphous. The specific gravity and the hardness of this gemstone are also still unknown. This information is essential to determine the quality of a gem. To answer those questions, we have used x-ray diffraction to study the bio-solar gemstone from the province of Aceh in Indonesia. The physical properties (specific gravity and hardness) of this gemstone have also been measured. We found that the bio-solar gemstone is composed by CaO, SiO2, MgO, Al2O3, Fe2O3, and TiO2 phases. Our results revealed that the bio-solar gem is a crystalline material, not amorphous. The average crystallite size of this gemstone is found to be 353 Å (35 nm). Moreover, the specific gravity of bio-solar gemstone is found to be 3.09 – 3.34. Its hardness is 3 to 4 mohs. Thus, the bio-solar is a good quality gemstone. Our finding confirmed that the bio-solar could be classified as a vesuvianite gemstone

Minerals Identification of Bio-Solar Gemstone From Aceh

Salah satu batu mulia yang terkenal di Aceh disebut Bio-Solar. Batu permata ini banyak ditemukan di Aceh, namun, informasi detail tentang batu permata ini masih sangat terbatas. Dalam penelitian ini telah dilakukan karakterisasi batu permata Bio-Solar yang berasal dari Aceh dengan menggunakan X-Ray Florescent (XRF). Hasil penelitian menunjukkan bahwa batu permata Bio-Solar mengandung mineral-mineral CaO (59,8%), SiO2 (19,7%), Fe2O3 (11,1%), Al2O3 (7,5%), dan NiO (1,3%). Dengan membandingkan hasil ini dengan data-data penelitian sebelumnya, telah ditemukan bahwa batu permata Bio-Solar dapat diklasifikasikan sebagai jenis batu giok Vesuvianite. One of well-known gemstones in Aceh is called Bio-Solar. This gemstone is found a lot in Aceh. Nonetheless, the detail information of this gemstone is still limited. None knows if this gemstone can be classified as jade. This study has characterized this gemstone (Bio Solar) from Aceh using X-Ray Florescent (XRF). The results show that the Bio-Solar gemstone contains minerals of CaO (59.8%), SiO2 (19.7%), Fe2O3 (11.1%), Al2O3 (7.5%), and NiO (1.3%). By comparing this results to the available mineral data, we found that the Bio-Solar gemstone from Aceh can be classified as Vesuvianite jade
