Sterling Silver (925)
The world’s most renowned and widely used standard for fine silver jewelry. Often marked as "SV925" or "Ag925" in Japan, this alloy combines 92.5% pure silver with alloy metals for enhanced hardness and everyday durability. It offers a brilliant white luster that balances classic beauty with long-lasting strength.
プラチナシルバーPt100

Platinum Sterling Silver (Pt-Silver)
An innovative hybrid alloy that blends sterling silver with a touch of pure platinum. While maintaining the brilliant, bright-white tone of fine silver, the addition of platinum significantly enhances tarnish resistance against sulfur and everyday oxidation. It delivers superior durability and enduring beauty at an accessible price point.
金(ゴールド)5K
金相場の価格高騰により、金のジュエリーも高額になるので、5Kという金属が誕生しました。色は綺麗なゴールド色で、ファッションジュエリーで使われ始めた新しいゴールドです。
5K Gold
An innovative, modern alloy developed in response to soaring gold prices. While offering a much more accessible entry point than traditional high-karat gold, it retains a beautiful, radiant yellow gold luster. Fast becoming a favorite in contemporary fashion jewelry, 5K Gold combines affordability, daily durability, and genuine gold elegance.
金(ゴールド)10K
従来ファッションジュエリーでよく使われていた金です。18Kの金より少し金色が薄い感じで価格も安いのも特徴です。
A classic staple in fine fashion jewelry, composed of 41.7% pure gold, 29.15% silver, and 29.15% copper. It presents a gentle, subtle champagne-gold tone that is slightly softer than 18K gold. Along with its refined, understated color, 10K Gold offers exceptional scratch resistance and daily durability at a much more accessible price point.

18K Gold (75% Pure Gold)
The ultimate global benchmark for fine jewelry. Composed of 75% pure gold balanced with fine alloys, it achieves the ideal harmony of a rich, radiant golden hue and lasting structural strength. Highly resistant to discoloration and wear, 18K Gold has long been the preferred choice of luxury houses and master jewelers worldwide.
ピンクゴールド10K(10金)

10K Pink Gold (Rose Gold)
Crafted by subtly increasing the proportion of copper within the alloy to bring out a delicate rosy blush. Compared to the deeper tones of 18K rose gold, 10K Pink Gold features a softer, gentle pastel-pink hue that melts naturally into the skin. It pairs the high hardness and scratch resistance of a 10K alloy with an understated, romantic elegance.
ピンクゴールド18K(18金)
K18の金よりも銅の配合割合を少し多くして、ピンク色にした金です。ピンクゴールドと言われる代表的な金属です。
18K Pink Gold (Rose Gold / 75% Pure Gold)

It delivers the signature weight, durability, and lasting brilliance expected of high-end fine jewelry.

Platinum 900 (Pt900 / 90% Pure Platinum)
