What is Malachite? The Appeal of Natural Stone Dials and the History of Stone Dials in the 1970s
Malachite is a natural stone with striking, vivid green hues and beautiful striped patterns.
Because its patterns resemble peacock feathers, it is called "Kujaku-ishi" (peacock stone) in Japanese.
As a mineral, it is a type of copper-containing carbonate mineral, and its deep green color and unique natural patterns are a major draw. The striped or concentric patterns differ for each individual stone, allowing you to enjoy the unique beauty characteristic of natural stones.
Malachite is also a historic stone that has captivated people since ancient times. It is believed to have been used as an ornament and pigment in ancient Egypt, and its elegant green color has been cherished across generations. With its mystical appearance, it is now highly popular not only in jewelry and crafts but also as a dial material for watches.
Natural stone dials gained particular attention in the watch world in the 1970s. In an era that valued individuality and luxury, many stone dials, such as onyx, lapis lazuli, tiger's eye, and malachite, emerged. The uneven natural patterns give each watch a special character, creating an appeal that makes industrial products feel like one-of-a-kind pieces.
The appeal of a malachite dial lies, above all, in its presence. The vivid yet elegant green brings glamour and depth to the wrist, revealing various expressions depending on how the light hits it. It harmonizes beautifully with both classic cases and modern designs, subtly enhancing the wearer's individuality.
Even with the same model, each natural stone dial has a different pattern. That's why a malachite watch can be enjoyed not just as a timepiece, but as a special, unique item. Stone dials are a fusion of the artistry created by nature and the aesthetic sensibility of watchmaking. Among them, malachite can be said to be a highly attractive material that combines history, rarity, and visual beauty.
Characteristics of Malachite as a Mineral
Malachite is a copper-containing mineral characterized by its vivid green color and beautiful striped patterns. Its chemical formula is Cu₂(CO₃)(OH)₂, with a Mohs hardness of 3.5 to 4 and a specific gravity of approximately 3.6 to 4.0. It is a relatively soft stone with a noticeable weight. Its crystal system is monoclinic.
◇Main component: Cu₂(CO₃)(OH)₂
◇Mohs hardness: 3.5-4
◇Specific gravity: approx. 3.6-4.0
◇Luster: Adamantine luster
◇Crystal system: Monoclinic
Malachite often forms from numerous layers of fine crystals, and these layers create the striped patterns of dark and light green or concentric patterns. When polished, these patterns become more distinct, highlighting the unique character of the natural stone. Unlike tiger's eye, which appears to have a moving streak of light, it is easier to understand malachite as a stone where the pattern itself is enjoyed.
Origin of the Name Malachite and Its Enduring Appeal
The name "Kujaku-ishi" (peacock stone) comes from the beautiful striped patterns on the stone that resemble peacock feathers. In English, it is called "Malachite," a natural stone with a long history whose name can be traced back to ancient languages.
In ancient Egypt, it was already used for jewelry and pigments, and its vivid green color was cherished as a symbol of special beauty. Its powder was also used as a mineral pigment and is known for the anecdote that Cleopatra incorporated it into her makeup.
Today, in addition to accessories and ornaments, it is also used for natural stone dials in watches. With no two patterns alike, malachite is a special material that allows you to enjoy the artistry created by nature on your wrist.
The Language of Malachite
Malachite is said to embody positive and pure meanings such as "reunion," "fulfillment of love," "healing," and "warding off evil."
It has been cherished as a presence that calms the mind, brings emotional balance, and gently encourages connections with loved ones and new beginnings.
◇Reunion
It is believed to signify reuniting with someone who has been distant or rekindling a broken connection.
◇Fulfillment of love
It is sometimes said to be a stone that nurtures love and helps feelings come to fruition, making it popular as a charm for romance.
◇Healing
It is believed to be a stone that eases mental tension and anxiety, leading to a calm state of mind.
◇Warding off evil
It is also cherished as a charm that protects against negative influences and brings a sense of security.
The 1970s "Stone Dial" Boom
Malachite gained attention as a watch dial material during the natural stone dial boom of the 1970s.
At that time, the watch industry was experiencing intense competition due to the quartz revolution.
Amidst this, luxury watch brands moved towards enhancing the value of mechanical watches through materials, artistry, and rarity. Watches with natural stone dials became a symbol of this trend.
Natural Stones Used in the 1970s
The following natural stones were used as dials in luxury watches of that era:
◇Tiger's Eye
◇Lapis Lazuli
◇Malachite
◇Onyx
◇Turquoise
◇Jasper
◇Aventurine
Malachite dial watches were popular among those who wanted to enjoy their watches like jewelry and those who valued individuality and glamour. In the 1960s-70s, they were favored by fashion-conscious women and the luxury segment seeking high-quality, special timepieces.
Natural Stone Dials Through Technological Innovation
Natural stone is very fragile and requires advanced processing to be used as a watch dial.
In the 1970s, processing technology was established to slice the stone thinly to about 0.3-0.5mm and adhere it to a metal base to create dials.
This made it possible to practically manufacture natural stone dials.
The Allure of Malachite Dials

The greatest appeal of malachite dials lies in their vibrant green hues and the beautiful striped patterns unique to natural stone.
Since no two stones have the exact same pattern, no two dials are identical, making the ability to enjoy a different individuality in each timepiece a major attraction.
The deep green, which emerges with every ray of light, is both striking and serene, giving the wrist a sophisticated presence. The organic beauty created by nature, unlike metal or conventionally painted dials, is unique to malachite.
Furthermore, malachite is a natural stone with a history of being used in ornaments and crafts since ancient times. This historical and artistic value also contributes to its special appeal as a dial material.
A malachite dial allows you to experience wearing a small piece of natural stone art, even though it's a watch. It is a special dial particularly suited for those who seek individuality, elegance, and rarity.
Re-evaluation of Natural Stone Dials in Modern Times
In recent years, natural stone dials have been gaining renewed attention among independent and luxury watch brands. The reasons are the unique natural patterns of each piece, their luxurious feel, and their value as art pieces. Today, natural stone dials made of aventurine, opal, tiger's eye, and other stones are once again capturing the attention of watch enthusiasts.
The "One-of-a-Kind Dial" Created by Natural Stone
The greatest appeal of a natural stone dial is that no two patterns are ever the same.
The patterns created by nature are all unique in each piece.
Therefore, a natural stone dial watch can truly be called a watch with a one-of-a-kind appearance in the world.
