A one-of-a-kind necklace crafted with a tube-included topaz. This exceptionally rare gemstone contains elongated, tunnel-like crystal formations that were naturally sealed inside during the topaz's creation. The densely packed crystals shimmer like silk, appearing as though light itself has drawn a quiet, bi-colored glow that floats gently up and down within the stone. The crystal evokes frost rising from the earth in the crisp morning air, where each breath turns white. From among these, we carefully selected a particularly beautiful piece—clear and pure, with a soft white hue resting within its transparency. Its inner expression shifts depending on the angle, and with every reflection of light, it transforms—at times appearing like a perfectly clear crystal, and at others spreading white in all directions like a snowflake—captivating all who gaze upon it. The softly rounded, horizontally set cushion cut is gently held by a matte K18 yellow gold setting, which enhances the stone's clarity and lends the necklace a quiet, refined presence. Topaz, also cherished as the birthstone for November, makes this necklace a meaningful protective charm for those born in that month.
