Aventurine by chance gemstone
Posted by: | CommentsAventurine by chance
Aventurine is a lovely green colour, the colour of jade or emerald. This gemstone is enhanced by flecks of mica or hematite which give a the polished surface a sparkling effect known as Aventurescence. Aventurine can also be found in other colours such as grey or red / brown.
Aventurine is found in Brazil, India and Russia amongst other countries.
So why do I call it the ” by chance ” gemstone? Aventurine comes from the Italian “A ventura” which translates to By chance and refers to a lucky find by an Italian of a type of glass containing flecks which can be used to imitate both aventurine ( green) and gold stone ( brown with gold flecks). This imitation is also used widely in jewellery but you should easily be able to tell the difference with a 10x lens where the glass will show the copper spangles as opposed to the more natural flecks in Aventurine.
Aventurine was popular during the art deco era as the green colour matched the fashion of the time.
In crystal healing Aventurine is supposed to be supporting and comforting. I calms anger and aids recovery.
The vintage jewellery necklace shown here is an original piece of art deco jewellery made with Aventurine polished into small slabs. It can also be found as beads, cabochons and even carved into cameos.

Amethysts, The sobriety Jewel

The amethyst in history and legend
The ancient Greeks and Romans believed that the amethyst protected from drunkenness, drinking from an amethyst bowl would keep you sober. In fact the word amethyst is derived from the ancient Greek work for intoxicated. The Legends of the Gods include variations of stories about Dionysus’s tears staining quartz purple to form amethyst.
The amethyst has been worn as a gemstone since at least Egyptian times
Is this a real amethyst or a piece of costume jewellery?
Whilst amethysts are quite abundant and not over particularly expensive as gemstones go, not every purple or violet stone you find is real. Some amethyst coloured stones are made of glass. Look deep into the amethyst with a 10 x magnifying class. Can you see round bubbles? if so it is most likely to be glass. Can you see tiger stripes? If so then your amethyst could well be real. You will need to take your gemstone to an experienced jewellery to be sure.
What makes an Amethyst valuable?
Like all gemstones the larger the better and the clearer the better. Amethysts can be quite opaque and cloudy and such stones are often turned into beads.
Care of Amethyst jewellery.
The amethyst is quite a tough material measuring 7 on Mohs scale . This means that any jewellery set with amethysts will be quite durable and it is suitable for wearing in rings. As with all jewellery you need to take a look at what the stone is set into before you decide how to clean it. If the amethyst is set into silver or jewellery and with no other stones present you may clean it in an ultrasonic cleaner without any real harm. Alternatively a quick dip in liquid jewellery cleaner should be OK ( not silver dip) . Rinse well and pat dry.

What an amazing vintage pendant and is in the antique baroque style although it actually dates from the early 1900s. This pendant is made of silver and set with a central real amethyst and baroque and round pearls (I am presuming the round pearls are cultured although I cannot test these without damaging them). The smaller “amethysts” are coloured glass. I have added a newer silver chain so that this pendant is ready to wear.

Amber, Jewellery from prehistory to today
Posted by: | CommentsAmber was one of the original jewellery materials used by our ancestors since the Bronze age or possibly before. The Greeks, Romans and ancient Celts all treasured amber set jewellery. More recently into Victorian Jewellery, in the Art Deco era and of course Amber is very popular nowadays. AntiquesAvenue takes a little look Amber and how it is used in Jewellery.
About Amber
Amber is the fossilized resin of pine trees, in the main it has been under the sea for 60 million years. Amber is found in a range of colours, normally we see it in honey shades but it can vary from a pale whitish or lemon colour through to almost black. Cherry red amber is very sought after and a natural amber in shades of blue is most rare. Natural amber is cut, carved and polished into the required shapes. As it is very soft for a gemstone is is possible to carve it quite intricately or alternatively it can be faceted. Most often we see amber polished smooth.

Care of Amber Jewellery
As Amber is quite soft it needs to be handled with some care, store it separately or protected from other pieces of jewellery so that it does not scratch. Also avoid leaving it in direct sunlight for a long time. Solvents in perfume and hairspray can damage your amber, the best thing to do is to use these first and put your amber jewellery on after. Perhaps clean it as soon as practicable after wearing.
When cleaning your amber jewellery please do not use an ultra sonic cleaner or harsh chemicals and do not use a jewellery dip. A soft cloth and a very tiny drop of pure olive oil are often recommended. If the jewellery is set into gold or silver you could try and clean the metal without toughing the amber.
How to tell Amber from Faux Amber
As Amber is so popular these days the price is rising and so fake or faux amber jewellery is being produced. How can you tell a real piece of amber from a piece of plastic or resin jewellery? The traditional method was to make a saturated salt solution, amber will float in this where as glass or plastic would sink. This method does not work on pieces of amber which are set into metal as they would sink with the weight of the metal. I have heard that if you stick a hot needle into amber that it smells of pine trees. I am not going to try this on a piece of amber jewellery as it would be damaged.
Here are two tests that you can try on your jewellery. Rub it against a piece of wool, its electrostatic properties produce static electricity which will attract dust. Secondly amber can glow a greenish yellow under an ultraviolet lamp

Value of Amber Jewellery
Amber Jewellery can be purchased fro about £20 upwards depending on the age, setting, size of the piece and craftsmanship. Very occasionally a piece of amber is found with an insect trapped into it and such pieces if genuine would fetch a few hundred pounds or more. Beware of fakes if the amber is set with an insect though and only buy from a very trusted source. Please pop over to my vintage jewellery shop at www.antiquesavenue.co.uk where I like to have one or two pieces of amber in stock.
Agate Jewellery, Victorian Pebble gems
Posted by: | CommentsAgate is a colourful form of Quartz gemstone which can be cut and polished into Cabochons or panels and set into jewellery. There are lots of different decorative agates which have been used for hundreds of years but became particularly popular in the Victorian era as part of the Scottish trend. Many of these agates were mined in Scotland although it is found world wide. I have made a little video which takes a look at some of the wide variety of Agates available as antique and vintage jewellery.
Value of Agate Jewellery
Agate is not a particularly expensive stone as it is quite common. The more decorative and colourful the piece the more value it has. The value in a piece of agate set jewellery (often known as pebble jewellery) can be in the setting . A silver or gold piece of jewellery set with agate is going to be more valuable than agate set into costume jewellery. The shape of the piece of jewellery is also important as is the size. A Victorian pebble brooch can cost as little as £30 rising in cost with desirability to about £150. I would not expect to see one at a much higher price than this unless it was by a famous maker, set into a heavy gold frame or had some other factor to boost the price.
Care of Agate Jewellery
Agate is quite a hard stone and so will wear well in jewellery and which is why we see so many antique pieces still in good condition. Take care not to drop the piece as I do see agates with cracks in them from time to time. Store pieces separately so that they do not rub together.
If the piece of Agate jewellery is set into gold or silver it is possible to give it a wipe with a damp cloth to clean it without any harm. Some agates have been dyed and so I would avoid cleaning chemicals if possible.
Examples of Agate Jewellery:
AntiquesAvenue.co.uk usually has a few nice agate brooches for you to choose from . Please do take a look int he Antique Brooches section.

If possible just lightly rub with a piece of lint free cloth. The Abalone will be set into another material and you may need to take special care depending on the material it is set into. A damp cloth can be used where necessary. Do not dip Abalone into jewellery cleaner or silver dip. Shell should never be cleaned in an ultrasonic jewellery cleaning machine.
