  • Diamond Key Pendant Unlock Your Elegance

    SKU: DP1262

    AUD $2,600.00 incl. GST

    There’s something undeniably magical about a key pendant. It whispers of mystery, meaning and the power to unlock life’s best moments. This diamond key pendant does just that—with a sparkling twist of luxury. Whether it symbolises unlocking love, success or a fresh start, this piece turns meaning into style.


     A Design That Shines With Meaning

    Crafted in warm, romantic 18kt rose gold, this pendant features a delicate key design encrusted with premium natural diamonds. The top is intricately shaped like a clover, a symbol of good luck and prosperity, shimmering with round brilliant cut diamonds. Even the key’s tip is finished with a touch of sparkle, creating a look that’s thoughtful, elegant and timeless.

    Gemstone: Natural Diamond
    Accent Stones: Round Brilliant Cut Diamonds
    Metal: 18kt Rose Gold (Chain not included)

    The balance of symbolism and sparkle makes this pendant more than just jewellery—it’s a personal emblem of strength, love or transformation.


     How to Style This Diamond Key Pendant

    It’s incredibly versatile. Layer it with a shorter 18kt rose gold chain for a modern stack, or wear it solo as a statement piece. Want to match it? Try pairing it with our diamond stud earrings from the collection.

    From birthdays to graduations, this pendant makes the perfect heartfelt gift. And yes—it makes an unforgettable self-gift too.


     Want to Try It On?

    There’s no better way to feel the magic than in person. Book an appointment at our Sydney boutique for a private styling session with our team. We’ll help you pick the perfect chain and match it with other beautiful pieces from our rose gold and diamond jewellery lines.

    FAQs: All You Need to Know About the Diamond Key Pendant

    What does a diamond key pendant symbolise?

    A diamond key pendant carries deep meaning—it often represents unlocking something special in life, such as love, success, wisdom or new beginnings. It’s a piece filled with intention, perfect for someone starting a new journey or celebrating a personal milestone.

    The diamonds add another layer of symbolism—representing strength, clarity and eternity. When combined with the key shape and warm rose gold tones, the pendant becomes more than jewellery; it’s a personal talisman. Whether you’re buying it for yourself or someone special, it holds emotional value that goes well beyond its sparkle.

    Can I wear this diamond key pendant every day?

    Definitely. It’s designed for both daily elegance and special events. The 18kt rose gold offers durability and a rich finish that holds up to regular wear. The diamonds are securely set, and the pendant’s weight makes it comfortable enough to wear all day.

    We recommend pairing it with a medium-weight rose gold chain to keep it secure and balanced. Avoid harsh chemicals and intense physical activities, and this pendant will stay stunning for years to come.

    Is this pendant a good gift?

    Absolutely. Key pendants are among the most meaningful jewellery gifts out there. They’re ideal for birthdays, graduations, anniversaries or even just to say, “I believe in you.” Add the diamond sparkle and rose gold glow, and you’ve got a gift that feels both personal and luxurious.

    Want to take the gifting experience to the next level? Book a private appointment in-store and have our team help you choose a matching chain, earrings or ring for a truly curated present.

    Does this pendant come with the chain?

    No, the chain is sold separately. That’s actually a good thing—it gives you the freedom to choose the look you want. For an everyday minimalist vibe, go with a thinner chain. Want it bold and eye-catching? Try a heavier diamond cut rose gold chain for added texture and shine.

    Need help finding the right one? Just book an appointment, and we’ll guide you through it.

    How do I style this key pendant?

    It’s super versatile. Wear it alone for a clean, elegant statement or layer it with shorter pendants for a trendy, stacked look. Because of its delicate yet detailed design, it pairs beautifully with diamond stud earrings or a matching rose gold bangle.

    It works just as well with a silk blouse as it does with a black dress. Casual or chic—this pendant adapts to your vibe.

    Can I see this pendant in-store before buying?

    Of course! Come visit our boutique in Sydney where you can try it on and get a feel for how it sparkles in real life. You’ll also be able to explore matching pieces, chains, and exclusive items not yet online.
