Made of metallic stainless steel. This ring is a masterpiece featuring a "Phantom Quartz" (Ghost Quartz) of collector's grade. Inside the highly transparent quartz, a fantastic inclusion floats, as if a small landscape is trapped within. The pattern woven by the reddish-brown and white layers evokes a mysterious atmosphere, reminiscent of misty mountains or a dying autumn forest. The delicate decoration surrounding the stone softly reflects light, further highlighting the phantom at the center. This ring, which holds a unique landscape created by nature over thousands of years on your fingertip, can truly be called a "gem that seals time." Notes: ***Photos are taken in natural light.
