Coloured Gemstone Engagement Rings

Coloured Gemstone engagement rings bring colour, character, and individuality that an all-diamond ring cannot. At Si Vis Amari, we specialise in coloured gemstone engagement rings built around exceptional stones, with a particular focus on sapphires in colours most jewellers do not carry. Every ring is designed using 3D sculpting software from the film industry and made in our UK workshop, giving us the freedom to create settings that showcase each stone’s unique colour, cut, and personality.

We work with sapphires, rubies, emeralds, tsavorites, aquamarines, and other coloured stones with the durability to withstand everyday wear. Every gemstone we source is selected individually for its colour saturation, clarity, and cut quality. No two are the same, and no two rings are the same.

Why Choose a Gemstone Engagement Ring

Coloured engagement rings have a long and distinguished history. Sapphires, rubies, and emeralds were the standard for engagement rings long before diamonds became the default in the 20th century. Today, coloured gemstone rings are experiencing a significant resurgence as customers look for something more personal than a white diamond. A coloured stone engagement ring tells a different kind of story. It might reference a birthstone, a favourite colour, a place, or simply a preference for something distinctive.

Beyond aesthetics, certain gemstones offer excellent durability for daily wear. The key factor is hardness, measured on the Mohs scale. We recommend gemstones with a minimum hardness of 7.5 for engagement rings that will be worn every day. This ensures the stone resists scratching and abrasion over years of continuous wear without losing its polish or brilliance.

Gemstone Durability and the Mohs Scale

Not every gemstone is suitable for an engagement ring. A stone that looks beautiful in a pendant or earrings may not survive the daily contact, knocks, and abrasion that a ring on your hand encounters. This is where the Mohs hardness scale matters.

The Mohs scale runs from 1 (talc) to 10 (diamond). For engagement rings worn daily, we recommend a minimum hardness of 7.5. Here is how the gemstones we work with compare:

Mohs 9: Sapphire and Ruby (corundum). Second only to diamond in hardness. Excellent for everyday wear with virtually no risk of scratching in normal use. This is why sapphire and ruby engagement rings are our strongest recommendation for coloured gemstones.

Mohs 8: Topaz. Very good durability for everyday wear. Resistant to most scratching.

Mohs 7.5 to 8: Emerald, Tsavorite, Aquamarine. Good hardness, though emeralds require more care due to natural inclusions that can make them more vulnerable to impact. Tsavorite and aquamarine are more robust at similar hardness levels.

We are transparent about which stones are ideal for daily wear and which require more careful handling. During your consultation, we will discuss durability alongside colour so you make an informed decision.

Sapphire Engagement Rings

Sapphire is our speciality. We carry an extensive selection of sapphires across the full colour spectrum, with a particular focus on the greens, teals, and pinks that most high-street jewellers do not stock. Sapphire sits at 9 on the Mohs scale, making it one of the hardest and most durable gemstones available for engagement rings.

Teal sapphire engagement rings are one of the most sought-after choices in coloured gemstone jewellery today. Teal sapphires blend blue and green in varying proportions, creating a colour that shifts depending on the light. No two teal sapphires look alike. Some lean towards ocean blue, others towards forest green, and the best examples display both colours simultaneously. We source teal and parti sapphires individually, selecting stones with strong colour saturation and clean clarity.

Green sapphire engagement rings range from soft sage to deep forest tones. Green sapphires have a natural, earthy quality that pairs beautifully with yellow gold and rose gold settings. Our green sapphire collection includes both solid greens and stones with subtle secondary hues of blue or yellow.

Pink sapphire engagement rings offer a softer, more romantic alternative to a traditional diamond. Pink sapphires range from delicate pastel to vivid hot pink, and the most prized examples carry a pure pink without secondary tones. They create striking contrast in both white metal and rose gold settings.

Padparadscha sapphire engagement rings feature one of the rarest gemstone colours in existence. A true padparadscha displays a delicate blend of pink and orange, often described as the colour of a tropical sunset or a lotus blossom. Genuine padparadscha sapphires are exceptionally scarce, and we source them individually on request.

Blue sapphire engagement rings are the most classic coloured gemstone choice, with a history stretching back centuries. We source blues across the full range, from the highly prized cornflower blue with its soft, velvety saturation to deep royal blue with intense, saturated colour. A diamond and sapphire engagement ring, with a blue sapphire centre stone flanked or surrounded by diamonds, remains one of the most timeless designs in jewellery.

Yellow sapphire engagement rings bring warmth and vibrancy. Yellow sapphires range from pale lemon to rich canary, and the best examples have an intensity that coloured diamonds at the same saturation cannot match at a fraction of the cost.

Purple sapphire and colour-changing sapphire are rarer options we source on request. Colour-changing sapphires shift between two distinct colours depending on the light source, typically blue in daylight and purple under incandescent light. They are among the most fascinating gemstones we work with.

Ruby Engagement Rings

Ruby is sapphire’s sibling. Both are varieties of the mineral corundum, sharing the same crystal structure and Mohs 9 hardness. The only difference is colour: corundum in red is classified as ruby, while every other colour is classified as sapphire. This means ruby engagement rings offer identical durability to sapphire, making them one of the most practical coloured gemstone choices for everyday wear.

Rubies range from pinkish-red to deep pigeon blood red, with the most valued examples displaying a pure, saturated red with strong fluorescence. A ruby diamond ring, with a ruby centre stone set alongside white diamonds, creates one of the most striking colour contrasts in jewellery. We source rubies individually, selecting stones with clean clarity and strong colour saturation.

Emerald Engagement Rings

Emeralds bring a deep, luxurious green that no other gemstone replicates. We have designed many emerald engagement rings, and the rich green of a fine emerald against gold or platinum is one of the most beautiful combinations in jewellery.

Emeralds sit at 7.5 to 8 on the Mohs scale, which provides good hardness, but they require more care than sapphires or rubies. Almost all emeralds contain natural inclusions, known in the trade as their “jardin” (garden). These inclusions are part of the stone’s character, but they can make emeralds more vulnerable to impact than cleaner gemstones. We will always discuss this with you during your consultation so you understand how to care for an emerald ring over the long term.

For customers who love the green colour but want maximum durability, we recommend considering a tsavorite. Tsavorite garnet offers a vivid green comparable to the finest emeralds but with fewer inclusions and better toughness for daily wear.

Tsavorite, Aquamarine, and Topaz

Tsavorite engagement rings feature one of the most underappreciated gemstones in jewellery. Tsavorite is a green variety of grossular garnet, discovered in East Africa in the 1960s. It offers a vivid, saturated green with exceptional brilliance and a hardness of 7 to 7.5. For customers drawn to green but concerned about emerald durability, tsavorite is an excellent alternative.

Aquamarine engagement rings offer a cool, pale blue that evokes sea and sky. Aquamarine is a variety of beryl (the same mineral family as emerald) but is typically much cleaner and more durable in practice. At Mohs 7.5 to 8, it handles daily wear well. The soft blue works beautifully in both white metal and yellow gold settings.

Topaz engagement rings are available in a range of colours, with blue topaz being the most popular. At Mohs 8, topaz offers very good durability. It provides an affordable entry point into coloured gemstone engagement rings without compromising on wearability.

Metals for Gemstone Rings

Every coloured gemstone engagement ring in our collection is available in four metals: platinum, 18ct yellow gold, 18ct white gold, and 18ct rose gold. The metal you choose has a significant effect on how the gemstone’s colour appears.

Yellow gold intensifies warm tones and creates a rich, traditional look with rubies, emeralds, and green sapphires. Rose gold complements pink sapphires and morganites with a harmonious warmth. Platinum and white gold provide maximum colour contrast, allowing the gemstone’s colour to stand out against a neutral background. This is often the preferred choice for teal sapphires and blue sapphires where you want the colour to speak for itself.

Our 18ct white gold uses a high palladium content alloy that maintains a natural silver-white appearance without rhodium plating, so the metal colour will not change over time.

All our metals are sourced responsibly and every ring is hallmarked by the Birmingham Assay Office in accordance with UK law.

Designing Your Gemstone Ring

Because every coloured gemstone is unique in its colour, dimensions, and optical properties, every ring we make is designed around the specific stone. We do not force gemstones into pre-made settings. The setting is sculpted in 3D to follow the exact geometry of your chosen stone, ensuring the metalwork enhances the colour rather than competing with it.

Coloured gemstone engagement rings lend themselves to a wide range of styles. A solitaire setting lets the stone’s colour dominate. A halo or hidden halo adds diamond brilliance around the colour. A vintage inspired setting with millgrain and engraving creates a period feel that many coloured stones naturally suit. Explore our unique and bespoke collections for further inspiration.

Pricing is quote-led due to the individual nature of each gemstone. Coloured stones vary widely in rarity, size, and quality, so we provide detailed quotes once we understand exactly what you are looking for. Get in touch to start the conversation.

Frequently Asked Questions

Are gemstones durable enough for an engagement ring?

It depends on the gemstone. We recommend a minimum Mohs hardness of 7.5 for engagement rings worn daily. Sapphire and ruby (Mohs 9) are excellent for everyday wear. Emerald, tsavorite, aquamarine, and topaz (Mohs 7.5 to 8) are good choices with reasonable care. Softer stones like opal or pearl are not recommended for daily wear engagement rings. We will always advise you on durability during your consultation.

What is the most durable coloured gemstone for an engagement ring?

Sapphire and ruby are the most durable coloured gemstones, sitting at 9 on the Mohs hardness scale, second only to diamond. Both are varieties of the mineral corundum and offer virtually identical durability. This is why sapphire engagement rings and ruby engagement rings are our strongest recommendation for everyday wear.

What colours do sapphires come in?

Sapphires come in virtually every colour. We carry an extensive range including teal, green, pink, padparadscha (pink-orange), blue (cornflower and royal blue), purple, yellow, and colour-changing varieties. Red corundum is classified as ruby rather than sapphire, but it is the same mineral. We specialise in teal and green sapphires, which most high-street jewellers do not stock.

Is ruby the same as sapphire?

Yes, ruby and sapphire are both varieties of the mineral corundum. The only difference is colour. Red corundum is classified as ruby. Every other colour, including blue, pink, green, teal, yellow, and purple, is classified as sapphire. Both share identical physical properties, including Mohs 9 hardness.

What is a teal sapphire?

A teal sapphire is a sapphire that displays a blend of blue and green, creating a distinctive colour that shifts depending on the light. Some lean more blue, others more green, and the best examples show both colours simultaneously. Teal sapphire engagement rings have become one of the most popular coloured gemstone choices in recent years. We carry an extensive selection of teal sapphires sourced individually for colour quality.

How do you choose which gemstone to use?

Every gemstone we use is selected individually based on colour saturation, clarity, cut quality, and durability. We do not use commercial-grade or mass-market stones. During your consultation, we will show you options, discuss the characteristics of different gemstone types, and help you choose a stone that matches your vision. If we do not have the right stone in our current selection, we will source one specifically for you.

Can I have a coloured gemstone with a diamond halo or shoulders?

Yes. Combining a coloured gemstone centre stone with diamond accents is one of the most popular configurations we make. A diamond and sapphire engagement ring, for example, pairs the colour of the sapphire with the brilliance of surrounding diamonds. We offer halo, hidden halo, shoulder set, and trilogy settings, all of which work beautifully with coloured gemstones.

Which metal looks best with a coloured gemstone?

It depends on the stone. Yellow gold intensifies warm tones and suits rubies, emeralds, and green sapphires. Rose gold complements pink sapphires. Platinum and white gold provide maximum colour contrast, ideal for teal and blue sapphires. Every gemstone ring in our collection is available in platinum, 18ct yellow gold, 18ct white gold, and 18ct rose gold. We will advise on the best pairing during your consultation.
