What is the best gemstone for an engagement ring?

Diamond remains the strongest all-round choice for daily wear. Sapphire and ruby are excellent coloured gemstone alternatives. Alexandrite and spinel can also be strong choices, while emerald and aquamarine may suit customers comfortable with more thoughtful design and care.

Which coloured gemstones are best for everyday engagement rings?

Sapphire and ruby are among the strongest coloured gemstone engagement ring choices. Alexandrite and spinel can also be suitable for regular wear when carefully selected and properly set.

Is sapphire good for an engagement ring?

Yes. Sapphire rates 9 on the Mohs scale and is highly regarded for rings. It is available in blue and many fancy colours, making it both practical and versatile.

Is ruby suitable for an engagement ring?

Yes. Ruby is corundum, like sapphire, and offers strong durability with vivid red colour. Treatment disclosure and quality review remain important.

Is alexandrite durable enough for an engagement ring?

Alexandrite is a strong candidate for engagement rings. It ranks 8.5 on the Mohs scale and is noted for excellent toughness and no cleavage, though fine natural material is rare.

Is spinel good for engagement rings?

Spinel ranks 8 on the Mohs scale and has good toughness, making it a durable coloured gemstone option for jewellery when carefully chosen.

Is emerald suitable for an engagement ring?

Emerald can make a beautiful engagement ring, but it generally needs more care than ruby or sapphire. Many emeralds contain fractures or clarity enhancement, so protective setting choices and gentle cleaning advice are important.

Is aquamarine durable enough for an engagement ring?

Aquamarine can be suitable for engagement rings and is often considered durable for jewellery. It is less hard than diamond or sapphire, so protective design and sensible wear are worthwhile considerations.

Should I choose a gemstone only by Mohs hardness?

No. Mohs hardness measures scratch resistance, but engagement ring suitability also depends on toughness, stability, cleavage, inclusions, treatments and setting design.

Can GemTrove help compare diamonds and coloured gemstones?

Yes. GemTrove can help compare natural diamonds, lab-grown diamonds and coloured gemstones according to beauty, suitability, setting style, durability and the customer’s brief.
