“Minerals grow, Plants grow and live, Animals grow, live, and have feeling.”
Carl Linnaeus, Systema Naturae

Since ancient times, minerals have been regarded as important elements of nature. It is believed that the origin of jewelry might date back to ancient times, when people wore found objects as talismans. The ancient people, embedded in nature, adorned themselves with stones, trees, animal bones, and so on, and may have felt a sense of protection through their connection with the universe.

Minerals are generated over a long period of time as a result of the accumulation of various factors, and they arrive to us finally as gems. No two natural stones have the same appearance, and this is a miracle of nature.

We work carefully to merely enhance the character of each stone we discover, to make it the most beautiful and long-lasting piece of jewelry you will ever enjoy.

At The Sixth Night in Tokyo, we take orders for one-of-a-kind pieces made with your choice of loose gemstone. Choose your particle generated by the universe.

Muska’s signature gems

Trapiche stones

Trapiche” is a Spanish word that means “sugar cane mill” or “olive press.” Trapiche stones are named after such mills because their pattern resembles the gears on them. Trapiche stones show their unique six-rayed spoke patterns. This pattern can be seen in many types of stones, such as rubies and sapphires. However, gemstones of this pattern are rare; moreover, it’s hard to find a beautiful one. The pattern consists of carbon; therefore, the cross-section may sometimes look rough.

Our designer is especially fascinated by the elegance of trapiche sapphires and emeralds. Even though the volume of the production is limited due to their rare nature, we have been making trapiche sapphire and emerald pieces, little by little, since the start of our brand.

Trapiche sapphires have a wide range of colors, such as dark blue, pale gray, yellow, and so on. Trapiche emeralds also come in various shades, but we prefer the clear, beautiful green stones, which are reminiscent of fresh grass.

Star sapphire

Star sapphires exhibit a star-like pattern. This pattern is caused by inclusions of needle-like crystals of rutile, which intersect in three directions and form an astronomical pattern called “asterism.” We adopt star rubies and sapphires for the element of “yıldız” which means “star” in Turkish.

Stars often appear clear and sharp by reflections of light, but we also prize the stone’s beautiful look even when the star is not apparent. The natural marble-like pattern of the shades is one of a kind.

We also apply mindful polishing to ensure the stone shines bright. Its enchantment is escalated to the highest degree when the stone is polished a second time by Japanese skilled craftsmen.

Unheated sapphire

In the process of transforming a natural stone into a gemstone, various treatments are sometimes applied to increase the stone’s durability or improve its color. Heat treatment is a common method used to change or homogenize the color of a natural stone by heating it.

However, we value the natural, beautiful coloration of unheated sapphires; therefore, we adopt them for the element of “yedi,” which means “rainbow” in Turkish. Unheated bicolor sapphires are rare and wonderful, and we are always amazed by the variation of sapphire’s colors.


black opal

Opals look like pieces of a planet. When the light hits, they show numerous faces due to their play-of-color, which shines like northern lights.

Our jeweler in Australia deals in outstanding opals. When we first saw them, we asked what made them so wonderful. They proudly introduced us to the old man sitting in the back. He said that he knows instinctively, at a glance, where to cut to make the opal most attractive. Today, our collection of opals is like the infinite universe thanks to them.
