Semi-Precious Gemstone Necklaces: How to Choose the Right One
Choosing a semi-precious gemstone necklace isn’t just about the stone, it’s about colour, setting and how it actually looks once worn. This guide breaks down the best gemstones, key design decisions and what to prioritise when choosing a necklace that feels considered and lasting.
Choosing a gemstone necklace isn’t about picking the most popular stone, it’s about choosing one that actually works once it’s worn.
A gemstone can look incredible loose, but completely different once it’s set, styled and worn. This is where most people go wrong, focusing on the name of the stone rather than how it performs as jewellery.
This guide breaks down the best semi-precious gemstone necklaces, what actually matters when choosing one, and how colour, setting and design come together to create something that feels considered and lasting.

How to Choose the Right Gemstone Necklace
Choosing a gemstone necklace isn’t about selecting a specific stone name, it’s about choosing the right colour, tone and presence for how you want the piece to feel.
A deep, saturated stone will create a very different look to something lighter or more translucent. The same gemstone can feel bold or understated depending on its tone and how it’s set.
- Choose colour first – saturation and tone define the piece
- Think about contrast with gold – yellow, white or rose changes everything
- Consider scale and placement – necklaces allow more freedom than rings

What Actually Makes a Gemstone Necklace Look Expensive
The biggest misconception is that size equals value. It doesn’t. What actually makes a necklace feel considered is colour, setting and how the stone reads once worn.
- Colour saturation matters more than size
- Setting defines the final look
- Contrast with gold changes everything
A smaller stone with strong colour will always look more intentional than a larger stone with weak tone.
How Colour and Saturation Change a Gemstone Necklace
Colour is what defines gemstone jewellery, but saturation is what gives it impact. Two stones can be the same size and type, but if one has stronger colour, it will always feel more considered and more valuable.
This is something that becomes very obvious once the stone is set. Softer tones can disappear against the skin, while saturated stones hold their presence and define the piece.
This is why gemstone jewellery at Argent + Asher is always built around colour first. The right tone creates the entire identity of the necklace, long before the setting is considered.
Setting Trends That Are Changing Gemstone Necklaces
- Georgian-style prongs - slightly undone, antique feel
- Bezel settings - clean, modern, protective
- Rhodium settings - sharper contrast, stronger colour
Coloured gemstones work particularly well in vintage-inspired settings, they bring depth and character that simpler stones don’t.
Best Gemstones for Necklaces
Turquoise
Turquoise works because it doesn’t rely on sparkle. It’s pure colour and presence. When the tone is strong, it holds beautifully against gold and doesn’t need over-designing.
Tourmaline
Tourmaline is one of the most interesting stones to work with because of the colour range. Teal tourmaline stands out, it sits between blue and green, which makes it feel modern and less expected.
Bi-colour tourmalines are where it becomes more distinctive. No two stones are the same, which gives each piece a completely individual feel.
Lapis Lazuli
Lapis has a depth that works particularly well in necklaces. The contrast against gold gives it a strong, vintage feel without needing complexity.
Amethyst
Amethyst works best when the colour has depth. Lighter tones can feel flat, but a strong violet reads beautifully once worn.
Aquamarine
Aquamarine is more understated. It works best in refined designs where the colour is present but not overly pale.
Tanzanite
Tanzanite offers something slightly different, a blue-violet tone that shifts depending on light, which works particularly well in necklaces.
What People Get Wrong When Choosing a Gemstone Necklace
- Choosing based on size instead of colour
- Trusting photos too much
- Ignoring how the stone will be worn
- Not considering setting style
In reality, how a gemstone performs once set is what matters most.
Choosing a Gemstone Necklace
When you move into bespoke, everything changes. You’re not choosing from what exists, you’re building around a specific stone.
At Argent + Asher, we source gemstones individually, which is where the most interesting pieces come from. Teal tourmalines, bi-colour stones, and unusual tones create something that can’t be replicated.
I have a bi-colour ametrine at the moment that shifts between gold and violet depending on the light, stones like that completely change how a piece feels.

Frequently Asked Questions About Gemstone Necklaces
Which gemstone is best for a necklace?
The best gemstone depends on the look you want. Turquoise and tourmaline offer strong colour and presence, while aquamarine and amethyst feel softer and more refined. At Argent + Asher, gemstones are chosen based on how they perform once set, not just how they look loose.
Are semi-precious stones good for necklaces?
Yes — semi-precious stones are ideal for necklaces because they allow for colour, individuality and design flexibility. The key is choosing stones with strong colour and setting them correctly in solid 14k or 18k gold.
What should I look for in a gemstone necklace?
Focus on colour first, then setting and how the piece will actually be worn. A smaller stone with strong saturation will always look more considered than a larger, weaker one.
Are gemstone necklaces suitable for everyday wear?
Yes, especially necklaces, as they experience less impact than rings. With the right setting and material, most gemstones can be worn regularly without issue.
