Diamonds have held a special place in our hearts, often nicknamed “a girl’s best friend” for so long. Sure they’re sparkling and stunning, but a diamond shaped like a heart? That goes way beyond the “bling”. It becomes a symbol of love, purity, and commitment, more than a lyric, more than a trend.
There’s something undeniably captivating about a diamond heart necklace. Whether nestled against a simple blouse or taking centre stage in an evening gown, heart-shaped diamond necklaces have become defining pieces in luxury fashion. They’re chosen not only for beauty, but for the stories they quietly hold.
In this guide, we’ll explore the history and evolution of diamond heart necklaces, the emotions they evoke, their meaning across cultures, and how to style them with confidence.
Tip: If you’re buying as a gift, a heart shape can be romantic or a symbol of self-love, context matters, and so does personalisation.
Historical Journey of Diamond Heart Necklaces
The story of heart-shaped jewellery goes back to the 15th and 16th centuries. It’s said that an Italian Duke, Galeazzo Maria Sforza, mentioned heart-shaped diamonds during a conversation with his advisor.
In the decades that followed, heart-shaped diamonds became prized by royals and aristocrats, symbols of wealth, power, and status. But a defining moment in the heart motif’s romantic legacy is often linked to 1562, when Mary, Queen of Scots gifted a heart-shaped diamond ring to Queen Elizabeth I of England. The heart became shorthand for love in jewellery, and it hasn’t faded since.
From courtly power to cultural icon
The popularity of diamond heart jewellery continued to grow. In the 19th century, famous jewellery houses such as Tiffany & Co. and Cartier elevated diamond necklaces into the realm of modern luxury, refining settings and design details that still influence silhouettes today.
And yes, pop culture played its part. The fictional “Heart of the Ocean” necklace from Titanic helped cement the heart-shaped diamond look in modern imagination, drawing on the drama and romance we associate with grand jewels.
Today, although heart-shaped diamonds can be more challenging (and therefore more expensive) to cut beautifully, diamond heart necklaces are far more accessible than they once were. You’ll still see them on red carpets and at landmark events, proof the shape remains a classic.
Modern story moments
Heart-shaped diamond necklaces are often gifted as symbols of friendship, milestones, and “I’m proud of you” moments, not only romance. That’s part of why the motif keeps returning, decade after decade.

How to Craft the Perfect Diamond Heart Necklace
A diamond heart necklace is a work of precision: balanced proportions, exact angles, and thoughtful setting choices that let light do its job. The heart of the piece (pun intended) is the diamond itself, either a single heart-shaped diamond, or smaller diamonds arranged to create a heart silhouette.
Setting styles that change the entire look
| Setting | How it looks | Why people love it |
|---|---|---|
| Halo setting | Centre heart framed by smaller diamonds | Extra brilliance and a more “statement” feel |
| Bezel setting | Metal rim holds the diamond securely | Modern, sleek, and protective for daily wear |
Metal choices
- Platinum / white gold: cool-toned metals that can make diamonds look especially bright.
- Yellow gold: warmer, vintage-leaning tone, beautiful if you want contrast and softness.
Three styles to know
- Solitaire heart necklace: one heart diamond in the spotlight, clean, simple, wearable.
- Heart pendant necklace: a delicate heart pendant on a fine chain, sometimes with accent stones.
- Heart cluster necklace: multiple diamonds forming a heart, high impact and light-catching.
Personalisation turns it into a keepsake
Many jewellers can engrave dates, initials, or a short message. Adding a birthstone is another beautiful option, bringing colour, symbolism, and a sense of presence to the design.

What Are the Deeper Meanings of Diamond Heart Necklaces?
Diamond heart necklaces are more than pretty jewellery. They’re like quiet messages you can wear. What they “say” depends on the moment, the giver, and the wearer.
A symbol of romance and commitment
Diamonds are known for strength and longevity, so a heart-shaped diamond necklace can express “I choose you, and I’m here to stay.” It’s a meaningful gift for partners, spouses, and life milestones.
A symbol of self-love and strength
The heart isn’t reserved for romantic love. Today, diamond hearts are also worn as a symbol of self-worth, an intimate reminder: “I matter.” The diamond’s brightness mirrors inner confidence and resilience.
A world of meanings
Across cultures, heart motifs and diamonds can hold layered symbolism. In some traditions, they’re linked to prosperity and marriage; in others, they’re exchanged by couples as a visible sign of commitment. If heritage matters to you, a diamond heart can be a way of carrying that story close.

How to Style Diamond Heart Necklaces
Diamonds aren’t only for “best dress” moments. A delicate heart pendant can lift everyday outfits instantly, think a crisp white shirt and jeans with a single, bright point of light at the collarbone.
Everyday styling
- Choose a smaller heart or a clean solitaire for a refined, effortless feel.
- Keep the chain length around the collarbone for maximum impact with minimal fuss.
- Let it be the “one” piece, especially for work or daytime plans.
Evening styling (where hearts really shine)
- Pair a larger heart or cluster design with a classic cocktail dress or gown.
- Don’t be afraid of bolder designs, clusters and halos create incredible light play.
- Keep earrings simpler if your necklace is the main character.
Layering, the premium way
For a modern look, layer a delicate heart pendant with a longer chain for depth. If you’re mixing pieces, keep one unifying detail, metal colour, stone size, or chain texture, so the stack looks intentional.

With proper care and periodic checks, a diamond necklace can last a lifetime and become a cherished heirloom.
