Inner diameter 18 mm. A cool Zeus with 15mm beads has arrived! (o^^o) Rainbow sparkling iris smoky citrine. A smoky, strong, chic color. It's powerfully beautiful. The gradation pattern is easier to see when placed on white paper or something similar and viewed in a bright place. It would be wonderful as a bracelet, of course, but also as a decoration in your room or entryway♪ It's quite difficult to find Zeus at an affordable price... If anyone is interested, please feel free to ask m(__)m Features and Meaning: Energy Fusion: Combines the "prosperity" and "financial luck" energy of citrine with the "grounding" and "purification" energy of smoky quartz. Powerful Purification: It is said to stabilize the energy of a space and have a strong purifying power. Rarity: It is rare for citrine and smoky quartz to mix naturally, and high-quality ones are particularly scarce. Appearance: The yellow of citrine and the brown of smoky quartz blend together, creating a unique pattern with layers or phantom (mountain-like) formations, which is very attractive. #Citrine #SmokyQuartz #NaturalStone #ZeusQuartz
