Golden sheen sapphire

Golden sheen sapphire, is a recently discovered variety of corundum. Goldsheen sapphire has been tested and confirmed in lab reports as "natural sapphire" by GIA, GIT, GRS, AIGS, Tokio gem labs and Lotus.
Goldsheen sapphire has a golden shine, almost like gold. Translucent blue, green or yellow material is sometimes present together with the gold. Particularly prominent is hematite which will often result in the formation of geometric hexagonal patterns within the gemstone crystal.

Evidence

Several articles, including the Journal of Gemmology state that gold sheen sapphire is high in iron and titanium oxide. It has inclusions of ilmenite, hematite and magnetite. It exhibits asterism and hexagonal growth, a lack of UV fluorescence, healed fractures and polysynthetic twinning. Golden sheen has a stronger golden shine and sometimes has blue and gold in the same stone.
