Why Sapphires are the Practical Choice
Sapphires (a type of corundum) rank 9 on the Mohs scale of hardness, second only to diamonds for most jewelry-grade stones. That makes them far more resistant to scratches, chips, and daily wear than opals. Sapphires are also very durable; they resist breaking, which makes them a popular choice for engagement rings, wedding bands, and everyday jewellery. They come in a range of colours (classic blue, but also pink, yellow) and are frequently heat-treated to enhance that clarity and colour; a trustworthy seller will disclose the treatments.

Why Opals Require Extra Care
The opal’s very own play-of-colour is what makes them so valued, although that beauty does come with some fragility. Being about 5.5–6.5 in hardness, opal scratches and chips a lot more easily. They also don’t much like shock temperature fluctuations, or being wet for a long time (some opals are hydrophane water suckers), either. For these reasons, opals are more suited to occasional-wear jewellery or designs that are built with protection in mind; chunky bezels, low profiles, or even use as an accent instead of a standalone star.
