Sapphire is the perfect choice for a gemstone ring, and it is the most popular option for coloured engagement rings. Sapphire is the second hardest gem following diamonds, so it is suitable for rings that are worn every day.
Not only are sapphires suitably hard for engagement rings, their beauty and symbolism make them a romantic and unique choice. In an engagement ring, sapphires are also believed to represent faithfulness. Sapphires were a popular choice for engagement rings in the middle ages, and they are still loved today, especially with royal approval from the likes of Kate Middleton (who wears the iconic sapphire ring that belonged to Princess Diana).
