About Moonstone
June
June Birthstone
Cancer
Jun 22 – Jul 22
Gemini
May 21 – Jun 21
Moonstone is a natural stone belonging to the feldspar group. As light enters its layered structure, a bluish glow shimmers from within like moonlight—the stone’s defining “schiller” (adularescence). The floating light shifts moment by moment with the angle of view and the direction of the light.
Long cherished as a “stone that holds the power of the moon,” moonstone symbolizes good fortune, love, and intuition. It’s said to heighten the wearer’s sensitivity and gently encourage a new step forward. It is June’s birthstone, and a stone associated with Cancer.
Materials & Finish
The thin and thick chains use different clasp sizes. Each uses a spring-ring clasp sized to the weight of its chain, and both are Italian sterling silver 925.

A Heart Shape Holding the Schiller
Within the softly rounded heart form, a bluish light shimmers gently. At approx. 6mm / 0.7ct, its well-judged size balances charm and elegance.

With no unnecessary treatment, the stone keeps the light and expression it naturally holds. Each one is different—a truly one-of-a-kind moonstone.

Sterling Silver 925 ｜ In Harmony with Nature
At SMUK, we believe in the power of nature.
That is why we care about the intrinsic value of the materials themselves, choosing sterling silver 925 as our main material.
Like natural gemstones, silver holds a gentle, nature-born energy. Since ancient times, it has been cherished as a symbol of intuition, emotion, and protection, quietly accompanying people in daily life.
In recent years, more accessories are simply stainless steel or brass with a silver-colored coating. They may look alike, but when the material itself is different, there is a real difference in how gentle it feels on the skin and how comfortable it is to wear.
By choosing with sincerity, down to the parts that no one sees, SMUK creates jewelry that feels good and can be loved for years to come.
