The black starstone cross with a stainless steel gold chain 45 cm (17.7 in) and an additional 5 cm (2 in) extension is an authentic monastic piece of jewelry from Mount Athos. The dimensions of the cross are 2 cm x 2.5 cm (0.8 in x 1 in), while the black starstone, with its characteristic shimmering reflections, exhibits a unique optical feature known as asterism, appearing like a star on the surface of the stone when illuminated by light. Combined with the shining gold chain, it offers elegance and a spiritual character, making it perfect for both everyday wear and special occasions.
