OPAL · PLANET NECKLACE
Like a tiny planet wrapped in rainbow light.
Opal shifts color with the angle of light. Its dreamlike play of color is set in a planet motif symbolizing the cycles of the universe and the earth. A delicate shine, like sunlight on the sea, rests softly at your neckline. Sterling silver 925 with rhodium plating keeps a clean, tarnish-resistant luster.
Opal (Composite)
A composite opal pairing a natural opal surface with synthetic opal beneath. The rainbow play of color that shifts with the angle keeps all the beauty of natural opal, while being easier to care for and more affordable. Opal is the October birthstone, symbolizing hope, luck and creativity.

Silver 925｜Why We Choose a Material Made to Last
SMUK jewelry is primarily made from Silver 925, an alloy containing 92.5% pure silver.
Unlike stainless steel or brass with silver-colored plating, where the underlying metal may become exposed as the surface wears away, Silver 925 is made of silver throughout.
・Even if it tarnishes, its shine can be restored with polishing
・Even if the plating wears away, the underlying material remains silver
・With proper care, it can be enjoyed for many years

"Why Choose Silver 925: Jewelry That Lives in Harmony with Nature"
SMUK uses four types of plating finishes, selected according to the materials and intended use of each piece of jewelry.
- Rhodium Plating
A finish made with a rare precious metal from the platinum group. It offers excellent resistance to tarnishing and scratches, with a clear, bright silver tone. Suitable for those with sensitive skin. - 18K Gold Plating
A finish made by coating sterling silver with 75% pure gold. It creates a rich, warm gold tone. - 14K White Gold Plating
A white gold finish with 58.3% pure gold content. Its soft, elegant white tone pairs beautifully with pearls and delicate designs. - Gold Vermeil
A finish featuring a thick gold layer of at least 2.5 microns over a Sterling Silver 925 base. It offers greater durability than standard plating, allowing its brilliance to last longer.
