Who Is Roberto Coin? Passion, Design and Symbolism
The Man Behind the Jewel That Hides Secrets
Roberto Coin was born in the captivating city of Venice. Interestingly, he did not start his career in the jewelry industry, but in the world of luxury hospitality. Over time, his refined aesthetic vision led him to seek a different form of expression, one that could capture beauty on a more personal level. In the 1990s, he founded his own jewelry brand, which quickly stood out for its unique approach to jewelry as an intimate and emotional message. Coin has always been deeply influenced by literature, art and Eastern traditions. His passion for storytelling has shaped collections that do more than please the eye. They connect with the emotions of the person who wears them. His entire body of work is a tribute to the modern woman, someone who is strong, sensitive and multifaceted. Within this artistic vision, the ruby has become his emotional signature. It is not just a visual detail, but a heartfelt message enclosed in every piece.The Origins of the Legend: Three Ancient Stories
The presence of the ruby in Roberto Coin’s jewelry is neither accidental nor purely decorative. The designer created this symbolic gesture based on three ancient legends from different parts of the world. Each story gives a unique layer of meaning to the ruby and enriches the emotional narrative behind every piece.Egypt: The Ruby as a Source of Joy and Eternal Health
In ancient Egypt, rubies were believed to bring happiness, love and everlasting health. Pharaohs thought that direct contact between the stone and the skin released the ruby’s inner energy and passed it on to the body. Rubies were used as talismans in royal tombs and rituals, regarded as sacred protectors of vitality and divine blessing.Burma: Warriors Protected by the Power of the Stone
In ancient Burma, rubies were considered magical stones that could protect the lives of warriors. Some believed in them so deeply that they would implant the stones under their skin to ensure invincibility in battle. This notion of direct physical protection plays a central role in Roberto Coin’s philosophy, where the ruby touches the skin to create a personal bond.India: Hindu Myths and the Tree of Wishes
In India, rubies are seen as sacred fruits of the mythical Caliph tree, a symbol of desire and hope. According to Hindu legend, owning a ruby attracts sincere love and prosperity. This belief reinforces the spiritual connection between jewelry and the human soul, making the ruby much more than just a precious gem.The Appassionata Collection and the First Hidden Ruby
In 1996, with the launch of the Appassionata collection, Roberto Coin introduced a revolutionary idea: a hidden ruby set inside each piece of jewelry. This concept marked the beginning of a new era in the way a designer could leave a personal mark. The name “Appassionata” reflects the intense emotion and deep love that Coin wished to convey through each creation. The first ruby was not visible from the outside. It was placed discreetly on the inner side of the jewel, touching the skin. This was not done for aesthetic reasons, but rather as an emotional gesture. It acted like a secret dedication, a silent blessing meant only for the wearer. Over the years, this ritual has remained unchanged. Today, the hidden ruby has become the most recognizable signature of the brand, and at the same time, one of the most discreet. It represents authenticity, care and meaningful intention.The Symbolic Meaning of the Ruby in Women’s Jewelry
Passion, Protection, Hope and Emotional Connection
Throughout history, the ruby has been associated with intense passion, sincere love and vital energy. In the world of women’s jewelry, it represents inner strength, sensuality and emotional depth. Unlike many other gemstones, the ruby is not just about sparkle. It moves something within us. Roberto Coin has masterfully captured this quality to elevate his creations into intimate, personal experiences. The ruby becomes a silent messenger, a way for the creator to communicate emotion directly to the person wearing the piece. This invisible connection is one of the brand’s greatest strengths. It builds a quiet bond between designer and wearer, without needing to shout or show off.A Hidden Message: Why Must the Ruby Touch the Skin?
Roberto Coin insists that the ruby must be in contact with the skin to fulfill its purpose. This decision is not a coincidence. It draws inspiration from ancient energy transfer rituals and the belief that natural stones can interact with the human body. With its vibrant color and deep frequency, the ruby represents vitality, emotional resilience and spiritual protection. When it touches the skin, it creates a direct connection between the artist and the wearer, a kind of invisible thread that transcends time, space and culture. This intimate detail transforms the jewel into something alive. It becomes a companion, a living object that evolves with the person who wears it.Brand Values and Commitment: Sustainability and Ethics
A Responsible Origin for Rubies: Myanmar and Mozambique
One of Roberto Coin’s greatest strengths lies in his commitment to ethical and sustainable production. The ruby, which has become the brand’s signature stone, is sourced from responsible mines located in Myanmar and Mozambique. These gemstones are extracted under strict guidelines that prioritize transparency, fair labor practices and environmental protection. This conscious approach is deeply embedded in the brand’s DNA, responding directly to the expectations of today’s consumer, someone who values not just beauty, but also ethical coherence and traceability.The Gemological Properties of the Ruby
Red Corundum, Mohs Hardness 9 and Chromium as a Pigment
The ruby is one of the most precious varieties of corundum, a family of minerals that also includes sapphires. With a hardness of 9 on the Mohs scale, rubies are exceptionally durable, making them perfect for everyday jewelry that retains its brilliance over time. Its intense red color is caused by the presence of chromium in its composition, and the tone can range from soft pink to deep blood red. Rubies sourced from Myanmar (formerly Burma) are particularly prized for their natural luminosity and depth. Another notable trait of the ruby is its fluorescence under ultraviolet light, which adds to its unique visual effect and helps confirm its authenticity. At Roberto Coin, every ruby is hand-selected by expert gemologists, ensuring that each stone meets the highest aesthetic and ethical standards.The Ruby as a Symbol of Royal Power
The British Crown and Other Historical References
For centuries, the ruby has been considered a stone reserved for royalty. It has adorned kings, queens and emperors across civilizations. In the British Crown Jewels, the most famous example is the Black Prince’s Ruby, which sits prominently in the Imperial State Crown, symbolizing power, longevity and divine protection. In France, historical figures like Catherine de’ Medici and Marie Antoinette also wore rubies to assert authority and prestige. In Asia, Chinese and Indian imperial dynasties regarded rubies as symbols of immortality and wisdom. This rich royal legacy resonates deeply in Roberto Coin’s creative vision. For him, jewelry is not about ostentation, but about personal dignity, inner strength and timeless beauty. The ruby is not just a precious stone, it is a legacy carried forward with reverence and intention.The Ruby in Classical and Modern Literature
The Bible, Marco Polo, Shakespeare and More
The ruby has appeared in some of the most foundational texts of Western culture. It is the only gemstone mentioned explicitly in the Bible, where it symbolizes wisdom and courage. In the writings of Marco Polo, the ruby is described as “the most noble gem that has ever existed.” Renowned poets such as William Shakespeare, John Donne, and John Milton referenced rubies as symbols of feminine beauty, often comparing them to the red lips of a beloved woman. This literary presence across centuries highlights the ruby’s evocative power as a metaphor for love and purity. Roberto Coin draws inspiration from this rich tradition and transforms it into a contemporary narrative. Every hidden ruby in his jewelry becomes a kind of unwritten verse, silent yet deeply felt.Jewelry with a Soul: The Concept of the Invisible Signature
One of the most distinctive qualities of Roberto Coin is his commitment to the emotional uniqueness of each piece. The hidden ruby, placed inside the jewelry, serves as an invisible signature, a personal imprint from the creator that is not meant to be seen, but rather to be felt. This idea breaks away from the common assumption that a brand must be visible to have value. In Coin’s world, authenticity is transmitted through discretion and intent, reaching the wearer on a symbolic level. It’s a subtle way of connecting the designer to the person who wears the piece, as if each jewel were a secret message, a love letter not read aloud but lived deeply. The ruby becomes a bridge of emotion between artist and wearer, hidden yet undeniably present.How Women React: Emotion and Connection
