The Asscher Pendant

There is something so satisfying about the Asscher cut. It's very architectural, with those crisp step-cuts that give off a lovely, quiet confidence. You'll find them in everything from cool aquamarine to rich sapphires.

They sit beautifully on a long chain and are a godsend if you enjoy the layered look; they provide enough structure to keep your other necklaces from looking like a bit of a jumble.

The Oval Gemstone Pendant

The oval cut is a real favourite for those who love deep, rich colours. The shape actually enhances the stone's natural dimensions, giving it a much more "alive" feel.

Its versatility makes it such a popular option. It has enough presence to be noticed without feeling too formal for daily life.

The Evil Eye Pendant

Meaningful jewellery isn't going anywhere, and the evil eye is still the ultimate symbolic piece. Set in solid gold with a striking emerald and delicate diamonds, it's a proper keepsake.

People love it because it's a protective charm that happens to look absolutely exquisite as a daily staple.

The Gold and Turquoise Pendant

Turquoise is one of the standout semi-precious gemstones of 2026. The gold and turquoise pendant, paired with an amethyst centre, brings together bold colour contrast and soft, organic shapes.

Inspired by floral symmetry, this piece feels expressive without being overly intricate. It's great if you're looking to introduce colour into your jewellery collection.

The Love Heart Necklace

The heart motif has returned, but with a more refined approach. Instead of heavy or overly decorative designs, the modern heart necklace features an open, minimal silhouette crafted in solid gold.

What makes this piece stand out is its customisation potential — it's available across a range of gemstones, so you can make it entirely your own.

The Necklace With An Eye

A more contemporary take on symbolic jewellery, this necklace features a sapphire centre surrounded by teal gemstones and a diamond halo. The compact size makes it ideal for everyday wear, while the detailing ensures it still catches light beautifully.

It's a strong example of how modern gemstone pendant design blends tradition with precision craftsmanship.

The Horoscope Sign Necklace

This lapis horoscope necklace is a really nice way to lean into personal jewellery. Instead of a basic gold coin, you get a beautiful, deep blue stone with your sign engraved on it — it just feels a bit more "luxe" and meaningful.

It's got a lovely, substantial feel that makes it a great gift, either for yourself or a friend.

The Turquoise Zodiac Necklace

For something a little more vibrant in the zodiac world, this turquoise necklace is lovely. The bold colour against the engraved gold creates such a striking effect, and it adds that lovely personal touch.

It's a brilliant example of the direction semi-precious gemstone necklaces are heading — more expressive, more personal, and beautifully crafted.

The Gold Tennis Necklace in Turquoise

The classic tennis necklace has had a bit of a facelift. By swapping diamonds for turquoise, the look shifts from "strictly formal" to something you can actually wear with a white tee. It's got that same polished, continuous line, but it feels much more relaxed.

A great option for anyone who finds traditional stone necklaces a little too safe.

The Lapis Necklace

If the turquoise isn't doing much for you, the lapis version is a beautiful, moodier choice. It's that same elegant line of stones but in a rich blue that goes with absolutely everything. Discover the top turquoise jewellery pieces here. 

It's the perfect bit of gemstone jewellery for when you want to look "expensive" in a subtle, low-key way.

How to Choose the Perfect Gift

• Think about what they usually reach for Have a quick look at their current collection. Do they love a bit of "less is more," or are they more of a "bold and bright" person? You want something that'll slide right into their usual rotation.
• Pick a "personality" stone One of the best things about gemstones is the meaning behind them. Giving someone an amethyst for clarity or a turquoise for protection adds that extra layer of "I've really thought about this."
• Consider their wardrobe A simple, neutral pendant is incredibly easy to style, but a multi-coloured necklace is a fantastic gift for someone who treats their jewellery like a work of art.
• Look for the "good stuff" You want a piece with a bit of staying power. Choosing solid gold and checking for quality craftsmanship means they'll still be wearing it years from now.
• Think about the drop Shorter necklaces are great for a simple look, while longer ones are perfect if they like to stack their gemstone jewellery.

The Right Necklace for Every Occasion

A well-chosen gemstone necklace will serve you right across multiple occasions — the key is matching the piece to the moment.

Where to Find Custom Designers in the UK

If you want our honest advice, go custom. There's something so much more satisfying about wearing a necklace that you've had a hand in creating.

At Argent & Asher, we handcraft everything in London, and it's all made to order. We use proper solid gold (14k or 18k) and we're quite picky about our gemstones, setting them all by hand. The clever bit is using CAD to get the structure perfect, but the soul of the piece comes from that hand-finished touch. It's the kind of jewellery that actually gains value over time because it isn't generic; it's a reflection of your life and your style.

What to Expect at Every Price Point

Price varies considerably depending on stone type, gold purity, and the level of craftsmanship involved. Here's an honest breakdown of what you'll find at each level.

The main factors affecting price are the type and quality of the gemstone, gold purity (14k vs 18k), design complexity, and the level of brand craftsmanship behind the piece.

What Makes Semi-Precious Gemstones Ideal for Necklaces?

There is a certain charm to semi-precious stones that is quite hard to replicate. Because they aren't as "uniform" as high-end diamonds, they tend to have more of a story in their grain and colour. They're wonderfully durable, too, so you needn't worry about wearing them out and about — it's just a brilliant way to own something authentic and striking without that sharp intake of breath when you see the receipt.

Take amethyst: that deep, velvety purple is just wonderful, and it's hardy enough that you can happily pop it on every single day. Then there's turquoise, which has this softer, almost earthy charm, while lapis lazuli gives you a rich, steady blue that looks smashing in cleaner, more tailored pieces.

And honestly, the sheer choice out there is what makes it all so brilliant. Your gemstone jewellery can shift and change with your mood instead of being stuck in the same old look.

Semi-Precious vs Precious: Which Is Better?

There's no "best" option here — only what works for you. Diamonds and rubies are classic, of course, but they often come with a high price tag. We find semi-precious necklaces much more exciting because you get so many more choices.

You've got endless colours, more modern designs, and they're affordable enough that you don't have to keep them locked in a safe. They're made to be lived in. For a versatile collection that stays high-quality but keeps things interesting, you really can't beat them.

The Rise of Multi-Coloured Gem Necklaces

We've all had our fill of "safe" jewellery, haven't we? That's why multi-coloured pieces are having such a moment. Moving away from the quiet, simple designs of the past few years has opened up so much room for personality.

Honestly, it's a lifesaver on those mornings when you've hit snooze one too many times. You just pop it on and it works with whatever you've pulled out of the wardrobe. No fuss, no faff.

Caring for Your Gemstone Necklace

Different semi-precious gemstones have varying hardness levels, so gentle care is what preserves both the stone and the setting long-term.

• Clean with warm water and mild soap A soft brush and a gentle soak is all most stones need to stay bright.
• Avoid harsh chemicals and perfume Spritz first, dress second — always put your necklace on last.
• Store in a soft pouch Prevents scratches from other pieces in your jewellery box.
• Remove before swimming or showering Chlorine and saltwater are not a gemstone's friends.
• Get occasional professional cleaning Once or twice a year keeps the setting tight and the stone looking its best for the long term.

The Conclusion

At the end of the day, picking out a semi-precious gemstone necklace isn't about following the "rules." It's about finding that one piece that makes you feel a bit more like you. Whether you're drawn to the steady, deep blue of a lapis or the protective feel of an evil eye, 2026 is all about wearing jewellery that actually says something.

If you're ready to find a piece that's got a bit of soul — and is made to last a lifetime — do pop over and have a look at Argent & Asher's gemstone jewellery collection. There's something quite special about wearing a piece that's been crafted with care.
