Materials & Finish
Sterling Silver 925
High-quality silver 925 with 14K white gold plating — strong tarnish resistance and refined lustre, providing a consistent, polished foundation for the zirconia edge setting.
Zirconia Edge
Zirconia set along the outer contour of the open heart — the continuous line of stones traces the silhouette with a delicate, even sparkle that reads with quiet elegance at the ear.
Open Heart Form
An open centre gives the heart silhouette a lightness and airiness distinct from a filled motif — feminine without being heavy, and closer to delicate than decorative in effect.
Hypoallergenic
Nickel-free and lead-free. Gentle on skin and suitable for those with metal sensitivities.

How to Wear
- A simple shirt or dress — the open heart silhouette and zirconia edge add a quiet feminine note at the ear that reads naturally within any look; delicate enough to sit alongside almost anything without competing
- Hair tucked behind the ears or worn up — the zirconia edge catches and scatters light against the neck, and the open centre of the heart gives the motif a lightness that reads with understated elegance
- A date, an anniversary, a special occasion — the combination of heart motif and zirconia sparkle carries just enough sentiment to feel appropriate without tipping into the overly dressy
- As a gift — for someone who appreciates feminine jewellery worn with restraint, or as a self-purchase for a piece that moves comfortably between everyday and special

925 Sterling Silver
SMUK believes in the quiet power of nature.
That is why we choose to work with materials that embody authenticity, using 925 sterling silver as our main metal.
Just like natural gemstones, silver carries a gentle energy born from the earth.
Since ancient times, it has been cherished as a symbol of intuition, emotion, and protection, quietly accompanying people through their lives.
In recent years, many accessories have been made from stainless steel or brass coated to appear silver, but even if they look similar, the difference in material makes a significant impact on how they feel against the skin and how comfortably they can be worn over time.
At SMUK, we carefully select every element with sincerity, including the parts you cannot see, to create jewelry that feels natural, comfortable, and made to be worn for years to come.

The Choice of Silver 925 — Jewelry that Lives with the Power of Nature
At SMUK, we use four types of plating finishes, each selected to suit the design and materials of the piece.
Rhodium Plating — A rare platinum-group metal. Tarnish and scratch resistant, with a bright, clear silver tone. Gentle on sensitive skin.
18K Gold Plating — 75% fine gold over sterling silver. Warm, deep gold color that flatters all skin tones.
14K White Gold Plating — 58.3% fine gold with a soft, cool white tone. Pairs beautifully with pearls and delicate designs.
Gold Vermeil — Sterling silver (925) base with a gold layer 2.5+ microns thick. More durable than standard plating with a longer-lasting shine.
