Materials and Expression Description

SENTE is a brand that expresses materials with silica (SiO₂) as its core.
Silica is the main component of quartz, glass, and opal, and is one of the most abundant materials on Earth.

At SENTE, we view this silica material in two main areas:
• SUISHO (silica crystal)
• SUISEI (including silica crystal and amorphous silica)

SUISEI is a unique SENTE material name developed by Aqua Jewelers for AQUA jewelry.
It includes not only glass-like states but also states that differ from glass.

SUISEI is not just a material name.
It is a word that represents our approach to creation itself: "how we face silica and how we encapsulate it."

SUISEI is categorized into the following three types based on differences in raw materials and origins:

SUISEI Sho
SUISEI material primarily made from crystal.
Available colors are limited to transparent, white, and black.

SUISEI
Standard SUISEI material made primarily from crystal with adjustments.
Colored items contain both crystal and silica sand.

SUISEI Kan
SUISEI material themed around circulation and recycling, using recycled glass, etc.

For approximately 14 years, from 2011 to 2026,
SENTE and water sculptor TAKAYUKI OTA
have been creating AQUA jewelry using optical glass made from quartz for scientific and chemical purposes.

Through repeated creation and expression, listening to the voice of silica, and responding to diverse expectations,
we gradually realized that there were areas that could not be fully expressed
with existing material categories, including optical glass.

In this process, while learning from the spirit of Japanese craftsmanship,
our creative approach shifted from treating materials merely as "substances"
to considering how to confront nature and how to sculpt water itself.

The material name "SUISEI," meaning "water spirit," is a word that embodies this philosophy and approach.

Suitai (The State of Water)

Water, though it is always water,
Transforms its appearance as it stays, resonates, or flows.
"Suitai" is the word that captures these different behaviors.

It is also a concept that describes how the material and creative approach of Suisei
Behave during the creative process.
It illustrates the nature of that movement.

Human expression, too, like water,
Can remain still, can waver,
Or can move towards a flow.

Kaisho (Standard Script) = Still Water
The forms are clear, the strokes are stopped, and order is maintained.
The meaning is unwavering, and readability is prioritized.
Power is contained within, the character's form closest to deliberate creation.

Gyosho (Semi-cursive Script) = Water Ripples
A flow emerges from Kaisho, and the strokes begin to respond.
Existing between order and disarray,
The character's form where the presence of writer and reader intersect.

Sosho (Cursive Script) = Flowing Water
The forms unravel, and the strokes become the flow itself.
Without stopping, without settling,
Movement takes precedence over meaning.
The character's form where the outline of deliberate creation dissolves, appearing as a flow.

"Soukei" is a word that describes the water-like surface appearance of AQUA jewelry and objects.

It is the final form that the behavior of water takes, manifested on the surface of the work. That is Soukei.

Wakei (Harmonious View)
A harmonious view of the world, gentle and accepting.
No competition, no resistance, just opening up to space.
Acceptance, harmony, quiet light.

Rekkei (Fierce View)
A fierce view of the world, intense and wild.
Breaking, leaping, revealing one's will.
Impulse, breakthrough, the power of life.

Yokei (Fluctuating View)
A view where stillness and intensity breathe simultaneously.
Calm and storm coexist on a single surface.
Ambiguity, humanity, transience.

Inherent Principles of AQUA jewelry

The state of being empty
is the baseline for AQUA jewelry.
It is not a default, but a zero point, and authentic.

What enters the water is the world itself.
Therefore, we don't list them, but rather perceive them as three categories.

① Mineral | MINERAL
Opal, ruby.
A crystallization of water and geological time.

② Metal | METAL
Gold, tin.
A symbol of civilization and human endeavor.

③ Life/Memory | TRACE
Deer antler, wood, coral, meteorite.
Not just materials, but traces of memory and cycles.
*Bones and ashes of beloved people or animals are handled under the YOSUI brand.

Lab-grown opal is a gemstone that occupies the same position as cultured pearls.
It is not a fake, but rather an opal grown in a laboratory by humans who understood and regulated the natural principles of opal formation.

It is not an imitation of glass or resin,
but is classified as synthetic opal in gemology.

Its stable quality, beautiful play of color, and resistance to cracking.
Furthermore, its characteristic of reducing environmental impact
is not a drawback, but a value that the times demand.

Lab-grown opal is not a stone that replaces nature,
but a stone born from learning the principles of nature.
It is a new form of gemstone that demonstrates what "authenticity" means in the coming age.

It was developed in the 1950s by French gemologist
Pierre Gilson.

AQUA OPAL is a gem that changes its form like water.
We captured these changes as four currents.

Shaping, wavering, shattering, melting.
The gem eventually unravels into a phenomenon.

1｜SENTE OPAL
(Cabochon & Sphere)
A perfected form, symmetrically arranged.
Water held within a vessel, imbued with light.

2｜BAROQUE
(Tumble)
An imperfect perfection, shaped yet yielded.
The wavering of water, born from the interplay of intention and randomness.

3｜PIRI
(Chip)
The core of the material, shattered into particles.
A fragment, a spark of origin.

4｜MILKY WAY
(Crush)
Shapes disappear, light diffuses.
A clustered form where the gem melts and unravels into a phenomenon.
