The Hidden Ruby: The Secret Signature Inside Every Roberto Coin Creation
There's a quiet kind of magic in knowing something no one else does. A whispered story tucked inside a beautiful object. A secret meant just for you.
This is the spirit behind one of the most romantic traditions in modern fine jewelry, and it's the reason we're so thrilled to welcome Roberto Coin to Day's Jewelers.
A Signature You Can Feel, But No One Else Can See
Hidden on the inside of nearly every Roberto Coin creation, resting against the skin of the woman who wears it, is a single small ruby. You won't see it on display. It doesn't sparkle from across the room. It isn't there to be admired by anyone but you.
That's exactly the point.
Roberto Coin sets a tiny ruby into the inner surface of each of his jewels: a private signature, placed where the gem will "kiss the skin" of the wearer. It was his way of forging an emotional bond between the artist, the piece, and the person who would one day call it her own. More than a maker's mark, the hidden ruby is a wish, a quiet message of love and good fortune, sent from the designer to the wearer across time.
A Stone Wrapped in Ancient Legend
Roberto Coin didn't choose the ruby by accident. For thousands of years, across cultures and continents, the ruby has been revered as one of the most powerful gemstones on earth.
According to ancient Egyptian belief, wearing a ruby close to the skin invited long life, health, and happiness into the wearer's days. Pharaohs carried rubies as talismans of divine favor. Warriors wore them into battle, believing the deep red stone offered protection and courage when it was needed most. In other traditions, the ruby was thought to be the sacred fruit of the tree of life — a symbol of vitality, passion, and prosperity.
Roberto Coin drew on all of this folklore when he made the ruby his signature. Every piece he creates carries with it the weight of those legends; a small, glowing reminder that beauty and meaning have always belonged together.
A Return to Authenticity
Long prized for their exceptional beauty and rarity, rubies have held a special place in fine jewelry for generations. Since 2016, Roberto Coin has chosen to feature an authentic, natural ruby in its jewelry — a quiet yet meaningful expression of the brand’s heritage and attention to detail.
It's a detail that speaks to who Roberto Coin is as a designer. Even the parts of a piece that no one will ever see are crafted with the same intention, the same artistry, and the same integrity as the parts that catch the light. Especially those parts.
A Secret Shared Between Friends
There's something wonderfully intimate about a hidden ruby. It turns every Roberto Coin piece into a small, private ritual. You slip on a bracelet, a ring, a pendant, and you carry a secret with you through the day. A gift of good wishes, pressed gently against your skin.
It also creates a quiet kinship between everyone who wears the brand. Two strangers passing on the street, each adorned with a Roberto Coin piece, share something neither of them needs to speak aloud. A symbol. A story. A wish.
That's the kind of luxury we love at Day's, the kind that's deeply personal, beautifully made, and full of meaning that lives long after the moment of unboxing.
