Umbra Lucis Ring emerges from the tension between light and shadow.A transparent bicolor tourmaline is held within silver, allowing color to shift and dissolve as light passes through - never fixed, never fully revealed. Like a moment suspended between states, the stone carries both presence and absence. Edges soften, tones transition, and form becomes a quiet threshold rather than a boundary. Made to order, each ring is individually crafted by hand. Variations in tone, internal structure, and the positioning of the bicolor tourmaline are inherent to the process, ensuring that every piece is truly one of a kind. Production time: approximately 10–14 business days from order confirmation. Note: The photographs show an example of the design.Due to the nature of handmade production and natural materials, each ring is unique and may vary slightly from the images shown.
