Coloured Gemstones Gemstone Jewellery, Worn With Meaning
Atlas is Masaat London's coloured gemstone collection — emerald, aquamarine and tourmaline set in 18ct gold and platinum, channelled into rings and necklaces. Explore by gemstone, by jewellery type, or by the occasion you're shopping for, with expert guidance on colour, durability and care along the way.
Carefully Selected Gemstones
Every stone in Atlas is chosen for its colour and character rather than an assumption of perfection. Natural inclusions are part of a gemstone's story, and we describe each piece's stone, cut and setting plainly on its product page.
Gemstone and Jewellery Guidance
Comparing an emerald to a tourmaline, or working out whether a stone suits daily wear, is a fair question to ask before you buy. Our team can talk you through durability, colour and lifestyle fit for any piece.
Fine Jewellery Craftsmanship
Every Atlas piece is crafted in the UK in 18ct yellow gold, 18ct white gold or platinum 950, with Single Mine Origin gold and finished by our setters in the North West.
Bespoke Gemstone Expertise
If you have a gemstone, colour or design in mind that isn't yet part of the ready-to-wear range, our specialists offer fully bespoke commissions — from initial sketch to finished piece.

Coloured gemstone jewellery starts with a stone whose colour speaks to you. Atlas is built around three: the deep green of emerald, the pale clarity of aquamarine, and the wide colour range of tourmaline, each set with diamond accents in gold or platinum.


Set in trilogy, halo, pavé and toi et moi designs, most finished with diamond accents. Emerald's natural inclusions make each stone genuinely individual.


A pale, understated blue — bezel-set, tension-set, or paired with diamonds in a toi et moi design. A popular choice for everyday wear.


The widest colour range in the collection — deep green, olive, blue-green and pink — usually in trilogy or toi et moi designs with diamond detailing.

Discover the Meaning Behind Coloured Gemstones
Coloured gemstones carry meaning that goes beyond how they look. Long before anyone graded a stone for clarity or cut, cultures around the world attached colour, rarity and origin to ideas of loyalty, renewal, protection and love — and many customers still choose a gemstone today because of what it's traditionally been thought to represent. None of this is scientific fact; it's cultural tradition and personal interpretation, and it's worth treating it that way rather than as a guarantee.

Gemstone Meaning, Symbolism and Personal Significance
Emeralds are traditionally associated with renewal and growth, largely because of their green colour and long history in royal and religious jewellery. Sapphires are commonly connected with loyalty and wisdom; rubies are often seen as a symbol of passion and vitality; and aquamarine is chosen by some to represent calm and clarity, echoing its pale, water-like tone. Tourmaline's broad colour range means its symbolism varies by shade — green stones are often linked to balance, pink stones to compassion.

Birthstones, Anniversaries and Meaningful Gifts
Birthstone jewellery gives coloured gemstones a practical starting point: a piece tied to someone's birth month reads as personal without requiring an explanation.
The same logic applies to anniversaries and milestone birthdays. Starting from colour or personal significance — rather than gemstone type alone — tends to lead to a piece that gets worn.

Why Choose Gemstone Jewellery?
Coloured gemstone jewellery offers something a diamond-only piece can't: colour as the main event. Every gemstone brings its own tone, saturation and internal character, so two rings set with the same gemstone type will still look distinct from one another. That individuality, combined with the option to pair a coloured stone with diamond accents, makes Atlas a natural home for anyone who wants a piece that reads as personal rather than off-the-shelf.

Colour, Character and Individual Expression
A stone's tone and saturation vary from piece to piece, and natural inclusions add character rather than detract from it. Atlas designs range from quiet, everyday pieces such as a pale aquamarine bezel ring to statement trilogy and toi et moi settings built to be noticed.

Gemstone Engagement Rings and Modern Alternatives
For anyone considering an alternative to a traditional diamond engagement ring, Atlas's emerald and sapphire-toned designs — built with diamond accents — offer a genuine middle ground between a fully coloured stone and a fully diamond one. Durability and everyday wearability are worth discussing with a specialist before committing to a centre stone. Bespoke settings are available for anyone building a ring around a specific gemstone.

Gemstone Jewellery Buying Guide
Buying coloured gemstone jewellery involves a few more decisions than buying diamond-only pieces, because gemstone type, colour and durability all vary far more than they do with diamonds. Here's what's worth thinking through before you buy.

How to Choose the Right Gemstone
Start with how the piece will be worn — an everyday ring needs a harder-wearing stone than an occasional necklace — then narrow down by colour, budget and personal meaning. A simple order to work through:
- Decide on the jewellery type (ring or necklace)
- Choose a gemstone or colour that appeals to you
- Consider how often the piece will be worn, and how durable the gemstone needs to be
- Look closely at the stone's actual colour, cut and any visible inclusions
- Ask about treatment and sourcing where it's relevant to you
- Choose a setting and metal that protects the stone appropriately
- Confirm your budget, including whether a bespoke commission suits you better

Gemstone Quality, Durability and Care
Coloured gemstones are judged on hue, tone and saturation rather than the strict colour/clarity/cut/carat framework used for diamonds — a vivid, evenly saturated stone can be more desirable than a paler one of the same clarity grade. Durability also varies by gemstone family, so a protective setting such as a bezel or halo matters more for some stones than others. For care: avoid harsh chemicals and prolonged heat, store pieces separately, remove jewellery before high-impact activity, and have settings checked periodically. Ask your specialist about care specific to your gemstone.

ExploreFrequently Asked Questions
There's no single best gemstone for everyone; it depends on the setting and how the piece will be worn. Harder stones like sapphire generally hold up well to daily use, while softer or more included stones benefit from a protective setting such as a bezel. A well-chosen setting matters as much as the gemstone itself.
Ruby and sapphire are both varieties of the mineral corundum; ruby is red, sapphire covers every other colour, most commonly blue. Emerald is a variety of beryl, valued for its green colour and typically containing natural inclusions. All three differ in hardness, common treatments and how they're cared for day to day.
Yes, provided the stone and setting suit daily wear. Harder-wearing gemstones set in a protective mount, such as a bezel or halo, tend to perform best as an everyday engagement ring. It's worth discussing durability and lifestyle with a specialist before choosing a centre stone.
Avoid harsh chemicals, remove jewellery before high-impact activity, and store pieces separately to prevent scratching. Some gemstones are more sensitive to heat, light or chemical exposure than others, so ask about care specific to your gemstone. Periodic professional inspection of the setting is also recommended.
The best gift usually starts with the recipient rather than the gemstone: their favourite colour, birth month, or a shared memory tied to a particular stone. From there, the occasion and how they tend to wear jewellery day to day will help narrow down the piece and setting.
Consider colour preference, how the piece will be worn, and budget together. A ring you'll wear daily needs a more durable, protective setting than a necklace worn occasionally. Personal meaning — a birthstone or colour with significance to you — is often the deciding factor once durability is accounted for.
No — natural simply means the gemstone formed in the earth rather than a laboratory; many natural gemstones are still treated, most commonly with heat, to improve colour or clarity. Any treatment should be disclosed as part of the product information, and it's a fair question to ask before buying.
Ask about the gemstone's identity, whether it's natural or treated, the metal and setting used, and the care instructions specific to that stone. It's also worth confirming returns and any warranty cover before you buy.
Yes. Alongside the ready-to-wear Atlas collection, Masaat offers fully bespoke commissions, working with you on gemstone selection, setting and metal from an initial consultation through to the finished piece.
Price depends on the gemstone, its size and colour, the setting, metal and any diamond accents, plus whether the piece is ready-to-wear or bespoke. Atlas ready-to-wear pieces are priced individually on each product page; a specialist can talk you through bespoke pricing based on your brief.
