An engagement ring does not have to begin with a diamond.
For many of my clients, the process begins with colour: a particular shade of blue, green or pink that they have always been drawn to, or a gemstone that feels more personal than something they have seen many times before.
As both a jeweller and gemmologist, I approach engagement rings through the stone first. Its colour, character, origin and suitability for the person who will wear it. A beautiful gemstone is important, but an engagement ring also needs to live comfortably within someone’s everyday life.
Here are some of the things I consider when helping a client choose a coloured gemstone for an engagement ring.
Begin With the Colour, Not Necessarily the Gemstone
You do not need to arrive at a consultation knowing exactly which gemstone you want.
It is often more useful to begin with the colours you are naturally drawn to. You might love deep ocean blue, eucalyptus green, pale lilac, smoky champagne or something that shifts between several colours depending on the light.
From there, I can suggest gemstones that carry that feeling while also considering durability, budget, shape and availability.
Sapphires are particularly versatile. Although they are most commonly associated with blue, natural sapphires can also occur in green, yellow, pink, peach, purple and bi-coloured and tri-coloured combinations. Some contain several colours within a single stone, making them especially difficult to repeat.
Diamonds can also offer more variation than many people realise, from icy white and warm champagne tones to salt-and-pepper inclusions and natural or laboratory-grown coloured options.
Consider How the Ring Will Be Worn
An engagement ring is usually worn more frequently than most other pieces of jewellery, so the wearer’s lifestyle matters.
Someone who works with their hands may need a lower-profile setting or a stone protected by a bezel. Someone who removes their jewellery during physical work may have more freedom to choose a higher or more delicate design.
Hardness is important, but it is not the only consideration. A gemstone can be hard enough to resist scratching while still being vulnerable to chipping if it has exposed corners or is struck at the wrong angle.
Sapphire and ruby are popular coloured choices for engagement rings because corundum is relatively hard and durable. Spinel can also be an excellent option in an extraordinary range of colours. Other gemstones may be suitable when the setting and the wearer’s habits are carefully considered.
There is rarely one universally correct gemstone. The aim is to find the right balance between beauty, practicality and the way you genuinely live.
Natural Variation Is Part of the Appeal
Many coloured gemstones contain zoning, inclusions or subtle variations in tone. These are not necessarily faults. They can be part of what gives a stone its depth and individuality.
A bi-coloured sapphire, for example, might move from blue into green or yellow across the stone. Its appearance can change in different lighting and from different angles. Another sapphire may have a velvety, even colour, while an Australian sapphire might carry a darker, inky blue-green tone.
When I source stones, I am looking for character rather than clinical perfection.
This also means that a particular gemstone may not be available again. If a ring is made around a rare or unusually coloured stone, I can create the same general design for another client, but the next gemstone will have its own colour, proportions and personality.
For clients who love the idea of something genuinely individual, this is often the most exciting part.
Think About the Shape as Well as the Colour
Gemstone shape changes the entire feeling of a ring.
An elongated oval or pear can feel elegant and slightly dramatic. A cushion cut often has a softer, older-world quality. Emerald cuts allow colour and internal features to be seen more clearly, while irregular or asymmetrical stones can make a ring feel like a small sculptural object.
The shape also influences how the gemstone sits on the hand and how the surrounding setting needs to be constructed.
I often prefer to design the ring after finding the stone rather than forcing a gemstone into a predetermined setting. This allows the proportions, metal and details to respond naturally to the individual stone.
Decide Whether You Want Something Repeatable
Some clients want a ring they have seen before, reproduced as closely as possible. Others want a piece that could never be made in exactly the same way again.
Neither approach is wrong, but it helps to know which is more important to you.
White diamonds, including laboratory-grown diamonds, are generally easier to source in consistent sizes, shapes and specifications. Unusual natural coloured gemstones can be far less predictable.
Choosing a rare sapphire may involve being open to small differences in dimensions, colour zoning or tone. Rather than selecting from a fixed catalogue, the process becomes a collaboration between the client, the stone and the jeweller.
Work With Someone Who Can Explain the Stone
When purchasing a coloured gemstone, ask about its identity, origin where known, treatments and suitability for everyday wear.
Many gemstones are routinely treated, and treatment does not automatically make a stone undesirable. What matters is that the information is disclosed clearly and that you understand what you are purchasing.
As a qualified gemmologist, I inspect and select gemstones with both their beauty and material properties in mind. I also work with trusted suppliers to source stones that suit the design, budget and individual preferences of each client.
Your Engagement Ring Should Feel Like You
The best engagement ring is not necessarily the largest, rarest or most traditional option.
It is the ring that feels unmistakably connected to the person wearing it.
That might mean a deep Australian sapphire, a pale Ceylonese stone, a colourful diamond or a gemstone with unusual inclusions and shifting tones. It might be set in a refined gold signet, an organic sculptural setting or something quietly minimal.
Colour gives us another language through which to make the ring personal.
