There are significant ruby formations across the world that have been commercialized. In Türkiye there are many mineralogical formation regions with gemological features of high quality. However, there is not enough information in the literature about the formation of ruby in Türkiye, and its usability as a precious stone. In contrast to previous studies, this paper was conducted to reveal the gemological properties of Doğanşehir (Malatya province) rubies and to investigate the usability of polished and cut ruby samples as gemstones. Ruby corundum formations of gemstone quality have recently been discovered in Göksun ophiolites in the Doğanşehir district of Türkiye. These ruby formations take place in greenish and grayish amphibolites in the Göksun ophiolites. The ruby crystals are observed in colors ranging from pink to red and sizes ranging between 2 × 10 mm and 30 × 50 mm. The tectonic position, geological environment, petrographic, mineralogical, geochemical, and gemological characteristics of Doğanşehir crystals indicate that they can be classified as rubies and can be likened to those gems formed in amphibolites in Tanzania. This indicates that Doğanşehir rubies have gemological and mineralogical parameters that are competitive with rubies existing in other places across the world after polishing and cutting. Examples of Doğanşehir rubies prepared by polishing and cutting show that these rubies may feature in the global market in the coming years. Doğanşehir rubies are suitable for COBACORE (community based comprehensive recovery) cutting mostly in large sizes and amounts. Thus, it is a potential gemstone source. Samples prepared by polishing and cutting indicate their suitability as gemstones.

Na całym świecie istnieją znaczące formacje rubinów, które zostały skomercjalizowane. W Turcji znajduje się wiele regionów formacji mineralogicznych o cechach gemmologicznych wysokiej jakości. Jednak w literaturze nie ma wystarczających informacji na temat powstawania rubinu w Turcji i jego przydatności jako kamienia szlachetnego. W przeciwieństwie do poprzednich badań, niniejsza praca miała na celu ujawnienie właściwości gemmologicznych rubinów z Doğanşehir (prowincja Malatya) oraz zbadanie przydatności wypolerowanych i ciętych próbek rubinu jako kamieni szlachetnych. W ofiolitach Göksun w dystrykcie Doğanşehir w Turcji odkryto niedawno formacje korundu rubinowego o jakości kamieni szlachetnych. Te formacje rubinowe występują w zielonkawych i szarawych amfibolitach w ofiolitach Göksun. Kryształy rubinu występują w kolorach od różowego do czerwonego i rozmiarach od 2 × 10 mm do 30 × 50 mm. Położenie tektoniczne, środowisko geologiczne, właściwości petrograficzne, mineralogiczne, geochemiczne i gemmologiczne kryształów Doğanşehir wskazują, że można je zaliczyć do rubinów i porównać do klejnotów powstałych w amfibolitach w Tanzanii. Wskazuje to, że rubiny Doğanşehir mają parametry gemmologiczne i mineralogiczne, które po wypolerowaniu i cięciu są konkurencyjne w stosunku do rubinów występujących w innych miejscach na świecie. Przykłady rubinów Doğanşehir przygotowanych metodą polerowania i cięcia pokazują, że rubiny te mogą pojawić się na światowym rynku w nadchodzących latach. Rubiny Doğanşehir nadają się do cięcia COBACORE (kompleksowe odzyskiwanie oparte na społeczności), głównie w dużych rozmiarach i ilościach. Jest to zatem potencjalne źródło kamieni szlachetnych. Próbki przygotowane przez polerowanie i cięcie wskazują na ich przydatność jako kamieni szlachetnych.
