What are Montana Sapphires?
Sapphires are probably our favourite gemstone here at Oval + Pear and something that makes them even more special is that they are mined all over the world (including here in Australia). Each location produces a sapphire which has their own unique qualities. For example Kashmir sapphires are know for their colour and silk inclusions, Australian produces amazing parti sapphires and Madagascan or Sri Lankan sapphires come in a rainbow of colours. Did you know that sapphires are also mined in Montana, USA? These sapphires have gained a lot of attention recently in the jewellery world as well as with collectors. Here are some reasons why:
- Sapphires have been mined in Montana since the second half of the 1800s. They were used predominantly for industrial purposes as they were green in colour which was undesirable.
- The four main mining areas are Rock Creek, Yogo Gulch, Dry Cottonwood Creek and along the Missouri River northeast of Helena.
- No one knows where they came from! The original source of sapphires in Montana is still being studied by geologists.
- Montana sapphires come in a variety of sorbet/pastel colours. These include purple, yellow and teal.
- Often Montana sapphires are heated to improve/intensify their colours which results in lovely shades of green, teal and blue. However, Yogo Gulch is renowned for producing excellent untreated blue stones.
- Montana sapphires generally don’t come in large sizes and are commonly under 1ct.
- They are ethically mined by companies ranging in size.
Montana sapphires are a lovely option for any ring. They’re array of colour will leave you spoilt for choice.
