CHOOSING THE STONE

Alternative Engagement Rings

An engagement ring does not have to be a white diamond. The alternatives worth considering, and the one question that decides whether a stone will last.

01

Does it have to be a diamond?

No. The white diamond solitaire became the default during the twentieth century, but rings set with coloured stones are far older, and many of the most famous engagement rings in history are not diamonds at all. What matters is that the ring suits the person and survives the life it will lead.

02

The question that decides it: will it last?

An engagement ring is worn every day for decades, so durability matters more than for almost any other jewel. Hardness, measured on the Mohs scale, tells you how well a stone resists scratching. Toughness, how well it resists chipping, matters as much.

StoneHardness (Mohs)Everyday wear
Diamond10Excellent
Sapphire and ruby9Excellent
Spinel8Very good
Aquamarine7.5 to 8Good, with a protective setting
Emerald7.5 to 8Good, with a protective setting; more brittle
Morganite7.5 to 8Good, with care
Tourmaline7 to 7.5Fair; better for occasional wear
Opal, pearl2.5 to 6.5Not recommended for daily wear

Coloured gemstones

The great coloured stones each bring something a white diamond cannot:

Sapphire
Hard, tough and available in almost every colour, from royal blue to teal and pink. The most practical coloured choice.
Ruby
The classic red, and as durable as sapphire.
Emerald
An extraordinary green, best in a protective setting and worn with a little care.
Aquamarine
The clear blue of seawater, which its name means in Latin. Brazil is one of the world’s great sources. Our Itapuã ring sets an oval aquamarine in woven yellow gold.
Spinel
Bright, hard and found in reds, pinks, blues and greys. Once mistaken for ruby in royal crowns, now loved in its own right.

Different diamonds

If you want the durability of diamond with a different look:

Fancy colour diamonds
Yellow, champagne, pink and blue diamonds. Natural ones are rare; lab-grown makes the colours more accessible.
Salt and pepper diamonds
Natural diamonds full of black and white inclusions, each one patterned differently. Usually cut in antique or rose cut styles.
Black diamonds
Opaque and dramatic, often treated to achieve an even black.
Antique and old mine cuts
Hand-cut diamonds with chunky facets and a softer glow.
05

Different designs

Sometimes the alternative is the design rather than the stone. A toi et moi pairs two stones, often a diamond and a coloured gem. An east-west setting turns the stone sideways. A signet or a bezel-set stone gives a quieter, more personal ring. An heirloom stone, reset into a new design, carries a family story forward.

06

Choosing well

Choose a stone hard enough for daily wear, or protect a softer one with a bezel or a lower setting. Ask for a report that confirms the stone is natural or lab-grown and states any treatment. And care for it properly: warm water, neutral soap and a soft brush, never an ultrasonic cleaner.

Questions

Does an engagement ring have to be a diamond?

No. Sapphires, rubies, emeralds, aquamarines and other stones have been used in engagement rings for centuries. Choose a stone that suits the person and is durable enough for daily wear.

What is the most durable alternative to diamond?

Sapphire and ruby, both 9 on the Mohs scale and very tough, are the most durable coloured stones for an engagement ring.

Is aquamarine good for an engagement ring?

Yes, with a little care. At 7.5 to 8 on the Mohs scale it resists everyday scratches, and a protective setting keeps it safe from knocks.

What is a salt and pepper diamond?

A natural diamond with many visible black and white inclusions, giving each stone a unique speckled pattern.

Can I use a family stone in a new engagement ring?

Yes. A stone can be removed and reset into a new design, carrying its history into a ring made for the person who will wear it.
