PREMIUM GEMSTONE — Stones That Carry a Little Luck
Ethiopian Opal · Moonstone · Silver 925 · Rhodium
PREMIUM GEMSTONE is SMUK's premium jewellery collection, created so the beauty of natural stones chosen from around the world can be enjoyed in daily life. Not just for special days, but as a natural companion to your everyday looks — bringing the character and glow that only a natural stone can offer. We weigh colour, clarity, brilliance and each stone's individuality, selecting one piece at a time.
Our Craft
Silver 925 × Rhodium, with a Four-Prong Setting
Every piece in this collection is sterling silver 925 with rhodium plating — resistant to tarnish and holding a clean, lasting shine. The rhodium is also meant to gently wrap and protect the stone's glow.
Each stone is chosen one by one for colour, clarity and the beauty of its cut. The four-prong setting lifts and supports the stone, drawing out its natural presence and dimension.
Not a size that demands attention,
but a presence that quietly expands.
