Indigo Iolite

6mm iolite rose cut round cabochon6mm iolite rose cut round cabochon

Also new in stock I have 4mm and 6mm rose cut iolite, at $3.15 and $13 per stone respectively. An interesting stone, with its pleochroic qualities; an indigo blue face-up colour (ideally!), but demonstrating browns, greys and yellows from different angles. In fact I have sometimes had customers contacting me to tell me their iolite is faulty, so clearly grey is it when viewed from the side. No, not faulty, just the nature of this fascinating stone. Legend has it that is was known as the ‘Viking Compass Stone’, and that thin slivers of the stone served as glare reducers and polarising filters that helped Viking marine navigators locate the sun on cloudy days, and therefore locate their own position. It’s a beautiful stone, taking it’s name from ‘ios’, the Greek for ‘violet’. It’s a fairly hard stone, at 7-7.5 on the Mohs scale, and for those who are interested in such things, not treated. It can’t be heat treated as it has a relatively low melting point so would not withstand the kind of heat that, say, sapphire would be subjected to to intensify its colour. This material is slightly included but has a good, saturated indigo colour. Click here to buy!

If there is one thing that people generally want to avoid in gemstones, it’s a fracture or a feather; whether the crack is surface reaching or completely included in the stone, there’s always the danger of it opening up and splitting or at least weakening the stone. More than that, […]

A Bluer Shade of Pale

by Julia Aufenast August 19, 2019 2 min read

Aquamarine is a really great choice of stone; it’s pretty gemmy without being insanely expensive, it cuts well and takes a really high polish. In its transparent form, it’s more pricey but I just love the milky variety; in lovely shades of pale blue to sea-green, it is misty, hazy and dreamy. It’s common to […]

When Prehnite Packs a Punch

by Julia Aufenast August 15, 2019 2 min read

Many years ago, shortly after I started out, the price of prehnite went shooting up. It was one of those odd things, where I had to do a bit of a double take. What could be going on? I was told, it was because it was being used as a jade substitute for the Chinese […]
