Gemstone of the Month: Carnelian

The birthstone for July is the carnelian, a form of chalcedony. It is usually offered as a brownish red coloured stone, but can range from pale apricot through bright orange to a darkish chestnut. It is found in Brazil, India and Uruguay, in forms translucent to opaque.

The chemical composition of carnelian is silicon dioxide, enhanced by iron to give it colour. It can be distinguished from reddish brown agates by the fact that the inclusions causing the opacity are cloudy and evenly distributed, and not organised into bands.

In the Granary Knits Etsy store, carnelians feature in a number of pieces of jewellery as part of a mixture or as standalone gemstones.

Gemstone of the Month: Moonstone

June‘s birthstone is the beautiful glowing moonstone.

Moonstone is part of the feldspar group of rock. it can be colourless, or pale yellow, with an internal sheen that is particularly lovely, like the shimmer of moonlight (hence its name). It is one of the potassium feldspars, with a chemical composition of potassium aluminium silicate. Deposits are found in Sri Lanka, Myanmar, Brazil, India, Madagascar and the USA.

In the Granary Knits Etsy store, we have both jewellery and stitch markers using a particularly lovely pale grey moonstone.

Gemstone of the Month: Emerald

The birthstone for May is the Emerald, a type of beryl, available as both a precious and semi-precious stone. The precious gemstone emerald is a rich glowing transparent green, the deeper the colour (and the more transparent) the more highly prized the stone. So beautiful is the stone it has given its name to the particular shade of green.

Its chemical composition is aluminium beryllium silicate, the colouring agent for true emeralds is chrome (other green beryls are coloured with vanadium, and should not be called emerald, but instead “green beryl”). It is mined in Colombia, Brazil, Zimbabwe, and many other countries around the world.

Semi-precious emeralds are clouded by inclusions, and may vary from pale to dark green. These are the type of emerald you will find in the Granary Knits Etsy store, in the form of earrings using selected shaded chips.

There are many large and well-known emeralds, mostly held in museums around the world, including the Natural History Museum in London, the American Museum of Natural History in New York, and the Topkapi Palace in Istanbul.

 

 

Gemstone of the Month: Rock Crystal

April’s birthstone (in the precious stone range) is the diamond, but diamonds are not everyone’s cup of tea, nor within everyone’s budget. But you can give as a gift a lovely clear sparkly stone that is affordable and pretty without taking out a second mortgage: the rock crystal.

This macrocrystalline form of quartz is named crystal from the Greek word for ice, as it was believed that rock crystal was eternally frozen. It’s chemical composition is silicon dioxide, with no other chemical additions to give it colour. It is found all over the world, but the most important deposits can be found in Brazil, Madagascar, the USA and the Alps.

At Granary Knits, we have recently been adding some rock crystal items to the shop.

A single stitch marker, made from a rock crystal bead which has a lovely crackled interior, is available as both a knitting and a crochet marker.

Spring is Finally Sprung!

To celebrate the arrival of Spring in the Northern Hemisphere, I have been designing some more spring-like stitch markers, and they are now available in store.

First, the Spring is Sprung set of knitting or crochet markers. This set of five features glistening golden beads, the colour of daffodils waving in a balmy breeze (currently here in West Yorkshire it is about +2 degrees Celsius, but I can dream!), and a lovely banded agate marker in the colour of purple crocuses. There are also plenty of charm markers – a sweet bird with a big heart, a cute rabbit peeking through his paws, a Tibetan silver flower bud about to open, and a graceful tulip.

Apart from the golden bead and bird charm, these markers are also available as single markers.

April will soon be here, and April’s birthstone is the lovely Rock Crystal. As well as a single marker and a set of markers, I have also added a pretty pair of rock crystal nugget earrings. Beautifully polished and light-catching, these earrings are just perfect as a birthday gift.

Finally, a new line in Jewellery for your Knitting and Crochet – stitch marker holders. I do send a small free cloth bag with each order, to keep your markers safe, but a clip to hold them all together is a welcome addition to my range. I shall be adding to the designs over the coming months, but my first two holders have been listed today and feature either a large feather charm or a large heart with a cutout pawprint. I am always on the lookout for larger charms as they are ideal for stitch holders, so watch out for future shop announcements!

Gemstone of the Month: Aquamarine

Another gorgeous gemstone features as this month’s gemstone of the month. Aquamarine is the birthstone of March, and as its name implies it is the colour of the sea. Aquamarine is a stunningly beautiful stone, semi-transparent to transparent, greenish-blue to pale blue, like the colour of seafoam.

Aquamarine is a type of Beryl and is related to emerald; its chemical composition is aluminium beryllium silicate, and owes its beautiful colour to iron. The most important deposits are found in Brazil, although it is also found in Australia, many countries throughout Africa, and China.

Here at Granary Knits, we use aquamarine in jewellery, both as single-stone pieces, such as these aquamarine earrings, and mixed with other gemstones and luscious glass beads to form individual unique pieces.

Gemstone of the Month: Amethyst

February’s birthstone is Amethyst, a beautiful richly coloured transparent to semi-transparent gemstone, ranging in hue from pale lilac to deep purple grape. It is the most highly valued stone in the quartz group, the most important deposits being found in Brazil. Silicon dioxide is its basic composition, coloured by traces of manganese, titanium and iron. Its name means not drunken in Greek, and was worn as an amulet against drunkenness.

Gemstone of the Month: Garnet

Garnet is the birthstone of January, and what a glorious colour it is. Rich burgundy red, with a deep shine; garnets are like little nuggets of warmth.

garnet_earrings_locking_scaledgarnet_knitted_earrings_hook_flat_scaled

Garnet is actually a group of stones with a similar crystalline structure – rounded crystals – and colour, a reddish brown. The name derives from the Latin for grain, granum, because of the rounded crystal structure and because of the similarity to pomegranate kernels. The basic chemical composition is aluminium silicate, and the gemstones within the group – pyrope, almandite, and spessartite – each has a different chemical addition which gives it its different colour. So pyrope is magnesium aluminium silicate and is red with a brown tint; this is the type most commonly sold as garnet. Almandite is iron aluminium silicate and is red with a violet tint; and spessartite is manganese aluminium silicate and ranges in colour from orange to red-brown.

You can see all the garnet items in the Granary Knits shop here.

Gemstone of The Month: Turquoise

Turquoise is one of those colours that just about everyone loves, and the gemstone Turquoise does not disappoint in the rich variety of its shades of light bluey-green. It is the birthstone of December, bringing colour and light to the dark months of the year.

The chemical composition is aluminium silicate which also contains copper, although the turquoise found in North America actually contains iron rather than aluminium; the latter tends to have dark veining.

Two types of Turquoise are commonly available: African and Chinese, although the stone is mined in many places around the world. African Turquoise tends to be a darker blue/green than Chinese, with darker threading throughout. Both types take polish well and gleam and glitter in jewellery.

Turquoise has featured in jewellery for thousands of years; it was used by the ancient Egyptians and Aztecs in jewellery and as a decorative stone; King Tutankhamen’s burial mask and tomb was inlaid with turquoise as the stone was a symbol of regeneration; the Mesoamericans created turquoise mosaics; the Chinese carved turquoise into ornaments; it was used by Native Americans in works of art and jewellery; the Tibetans believe in its healing properties and have valued turquoise jewellery for centuries.

Gemstone of the Month: Citrine

Citrine is the birthstone for the month of November. It is a quartz, and its chemical composition is silicon dioxide coloured with iron. It is not as flashy a gemstone as lapis lazuli, or malachite, or emerald, but it does have a quiet beauty all of its own.

It ranges in colour from light yellow to golden brown, and is only found in a transparent form. Natural citrine is rare, and most commercially available stones are actually heat-treated amethyst or smoky quartz; heat-treated stones nearly always have a reddish tinge to them, enabling the discerning to detect that the stones are not true citrines. Natural citrine is found mainly in Brazil, Madagascar and the United States, with minor deposits in Argentina, Myanmar, Namibia, Russia, Scotland and Spain.

Citrine makes lovely delicate unusual jewellery. See the Granary Knits store for these and other designs.
