The Bone Hourglass is a stylized, hand-painted artifact resembling an hourglass with a frame crafted from aged, yellowish bones, intricately carved with Greek mythological motifs. The glass chambers are filled with a luminous, sand-like substance that glows faintly, shifting colors between gold and deep red as time passes. The base and top are adorned with small, ornate bone figurines depicting mythical creatures, adding a layer of mystique and ancient power to the item.
