When people think about jewellery, diamonds often come to mind first.
But there’s another option that’s just as eye-catching, without the high price tag or ethical concerns and it’s cubic zirconia (CZ). This lab-made stone looks a lot like a diamond, but it’s more accessible, versatile, and sustainable.
At Aquila, we use CZ in some of our most popular designs for that bit of sparkle that doesn’t harm the planet (who doesn’t love a bit of sparkle from time to time).
So, what exactly makes cubic zirconia so appealing? And is it the right choice for you? Let’s explore…
What is Cubic Zirconia jewellery?
Cubic zirconia is a man-made gemstone that’s been around since the 1970s. It was created to mimic the appearance of diamonds but at a fraction of the cost.
To the naked eye, it’s surprisingly similar, most people wouldn’t be able to tell the difference without special equipment!
The big difference is in how it’s made. CZ is created in a lab, not mined from the earth. That means fewer ethical issues and a much smaller environmental impact.
Quick takeaway: What is cubic zirconia jewellery? It’s the sparkle and style of a diamond, without the cost or complications.
Benefits of cubic zirconia jewellery
Now, why should you choose cubic zirconia over other stones?
We’ve put together the key benefits of cubic zirconia jewellery (and they might surprise you).
Durability for daily wear
CZ is strong enough to withstand everyday use. While diamonds are harder, CZ holds its own when firmly set.
Maximum sparkle
Ever noticed how CZ often gives off a rainbow-like shine? That’s because it reflects light in a slightly different way than diamonds. Whether it’s a cubic zirconia pendant or earrings, the sparkle is guaranteed to shimmer.
Accessible price
Love bold jewellery but not the cost of diamonds? CZ lets you enjoy statement pieces without stretching your budget.
Ethical and eco-friendly
Since it’s lab-grown, CZ avoids the environmental and human costs linked to traditional gemstone mining.
Our favourite cubic zirconia jewellery

Here are our faves:
Hella Dainty Silver Star Bracelet
Our Hella dainty silver star bracelet ticks every box. Made with recycled and resilient 925 sterling silver and set with sparkling cubic zirconia, it’s adjustable to fit most wrists and designed for everyday wear.
Inspired by the rugged landscapes and midnight sky of Hella, Iceland, the Hella bracelet’s delicate star motif mirrors the natural shimmer of the Arctic sky.
Each cubic zirconia stone is set to catch the light just like stars reflecting off icy waters. Durable, stylish, and ethically handmade using age-old techniques and handheld tools, this bracelet tells a story of adventure, the simple beauty of nature and how the stars in the night sky can always lead us home.
Also available in gold.
Dainty Silver Triangle Pendant
This pendant takes its shape from clean geometric lines, a nod to minimalist Scandinavian design. The triangle sits delicately yet confidently, catching the light in a way that makes it stand out whether worn alone or layered with other favourites.
Designed in Brighton and handmade in Thailand, each piece is crafted using age-old silversmithing techniques. That means the pendant doesn’t just look refined, it’s made to last.
The central stone adds just the right amount of sparkle, sitting like a single star set against a clear sky.
Available in both silver and gold, so you can choose the finish that feels most you.
Small Silver Triangle Earrings
Geometry meets subtle sparkles in these recycled 925 sterling silver triangle studs.
Their crisp, 6mm silhouette is minimalist in shape, giving them a sharp yet understated look. The triangular form isn’t just a shape, it creates tiny angles that naturally catch and reflect the light, giving the cubic zirconia at the centre even more brilliance.
Every pair is by our expert artisans, meaning each setting is finished with a precision that machine casting can’t replicate.
Small enough for everyday wear, yet crafted with a detail that rewards a closer look, these earrings carry a subtle flash of light and a whisper of wanderlust, a reminder of the journeys and hands that shaped them.
Also available in gold if you prefer a warmer glow.
Is Cubic Zirconia Jewellery ethical?
The short answer: yes. Because CZ is man-made, it doesn’t involve mining, which can cause serious damage to ecosystems and raise human rights concerns.

Cubic Zirconia vs Diamonds: What’s the difference?
It’s worth asking: how does cubic zirconia compare to diamonds? Here are a few key differences:
-
Hardness. Diamonds are the hardest natural material on Earth. CZ is softer but still durable enough for daily wear.
-
Cost. A CZ stone is a fraction of the price of a diamond, which means you can invest in more styles.
-
Appearance. Diamonds have a subtler sparkle, while CZ tends to reflect light in brighter rainbow colours.
-
Origin. As we know, diamonds are mined, CZ is created in a lab. That alone makes CZ a more eco-conscious choice.
Would you rather have one very expensive diamond piece you rarely wear, or several CZ pieces you can enjoy every day? For many people, it’s an easy decision.
How to style cubic zirconia jewellery
Cubic zirconia isn’t just for “dressy” occasions. It’s versatile enough for everyday looks too.
Here are some suggestions…
Layering necklaces
Try a cubic zirconia pendant layered with simple chains for a relaxed but polished style.
Festival-ready sparkle
Pair CZ earrings with boho-inspired pieces for a playful look (see our blog Festival Jewellery – Trends To Know This Summer).
Travel-friendly jewellery
Taking CZ pieces on holiday is low stress – you don’t have to worry about travelling with high-value stones. For tips, see Holiday Jewellery That Packs Style.
Do you prefer to keep things minimal or layer up with lots of detail? CZ works either way.
Caring for Cubic Zirconia Jewellery
Does cubic zirconia last?
Yes it does, especially if you look after it properly.
Here are a few simple tips:
-
Avoid harsh chemicals like chlorine or cleaning sprays.
-
Give your CZ a quick clean with warm soapy water and a soft cloth.
-
Store your pieces separately to avoid scratches.
With the right care, CZ jewellery will stay looking its best for years.
Why Choose Cubic Zirconia?
For us at Aquila, jewellery is about more than looks, it’s about meaning, style, and sustainability. With cubic zirconia, you get all three: strength for everyday wear, a shine that rivals diamonds, and a choice that feels good to make.
And isn’t that the whole point? Jewellery shouldn’t be locked away for special occasions. It should travel with you, tell your story, and add a little sparkle to the everyday.
