Celebrating Opal – the birthstone for October
October’s birthstone is Opal. Subtle in beauty, diverse in colour and perfect for October birthdays and anniversaries.
Owing to the diversity of shapes, sizes and colours, we create most Opal jewellery by bespoke design. To explain, no two Opals are the same. Furthermore, the colours vary from white to black with variations in orange from Fire Opals.

What is Opal?
Opal forms from a solution of silicon dioxide and water. Water flows through the earth and collects Silica from sandstone.
A Silica-rich solution falls into cracks and voids, caused by natural faults. As the water evaporates, it leaves behind a silica deposit. Over a long period of time, Opal forms.

Where is Opal mined?
October’s birthstone Opal comes from many different countries. These include Australia, Ethiopia Mexico and USA. In addition, from the Czech Republic, Hungary, Brazil and Indonesia.
Caring for Opal. How delicate is October’s birthstone?
Opal’s toughness can be described as poor to fair—5-6.5 on Mohs scale of hardness. Most importantly, Opal does not respond well to changes in temperature. For example, intense heat can craze the surface. Moreover, Opal does to fair well over time in dry conditions. For this reason, we recommend cleaning in a gentle warm soapy water. Also, we suggest an Opal necklace or pair of Opal earrings rather than an Opal ring.
Opal rings often receive wear through damage whilst on the hand. Unlike rings, both pendants and earrings avoid similar wear. For this reason, they are the perfect luxury gift for an October birthday or anniversary.
