Ruby
Ruby gemstones can vary greatly in price so how does the jeweller or stone buyer get value for money ? To make a choice several factors should be taken into consideration before buying this stunning gemstone.

Colour of your ruby gemstone should be a blood red some prefer the true traffic light red whilst others prefer a slight purple tinge . ( there is no empirical test to distinguish a dark pink sapphire from a light red ruby).

Cut look for chips and uneven cuts , see the picture above . Gemstones with chips or uneven cuts should sell for a reduced price.

Unheated Rubyfair only sells unheated stones but many sellers heat stones which reduces their value.

Origin this may not directly effect the value of the stone but the ethics of how the ruby was mined, cut and exported may be of interest to you and the person who finally receives the ruby. Rubyfair has its own ethical mine please see the website for further information.

Tanzanite how do I choose the right Tanzanite for me ?

A true 4A Tanzanite .

How do you go about choosing a Tanzanite ?

Ok you have decided to buy a Tanzanite or maybe you just want to know more about this stunning gem. Maybe you are a jeweller and this gem is new to you. Here are a few pointers we have picked up along the way. If you want to know more about the history of the Gem and its properties take a look here ( Don’t forget to come back ! )

Tanzanite can range vastly in price depending on quality . At Rubyfair.com we are lucky. Our in house gem cutter has a Tanzanite mine plot so we get to choose the top quality rough stones which he then cuts in Tanzania; the home of Tanzanite . Beware anyone offering Tanzanite not cut in Tanzania or rough uncut stones . The Tanzanian government has introduced strict laws on the export of uncut Tanzanite so the host country , Tanzania, gains from its own resources. If unsure ask to see the relevant documentation Certificate of Origin all rubyfair.com Tanzanites can be traced back to Tanzania.

Tanzanite varies in price from $100 – $1500 ( £60 – £1000, 80 euro -1200 euro )  per carat varying in carat size ( ref Exotic Gems Vol 1 Renee Newman GG published IJP ) , colour and cut quality. You can see from rubyfair.coms prices we have set our carat price at about midrange although our stones are at the top end of quality.

Tanzanite is a ‘clean’ stone it must be at least eye clean and the good ones are similar in quality to VS or VVS diamond IE loupe clean . Any stones with fractures should be heavily discounted ( we don’t hold stones of this quality ).

The key price factor is a deep dark blue. If you see a pale / light aquamarine colour or sky blue this stone should be at the lower end of the price scale.

Tanzanites do have a variation of purple in them due to Pleochroism and some even have a hint of green when viewed in different lights from different angles. This is a matter of taste but the deep blue colour should always be there.

Make sure the cut of the Tanzanite gives a full colour. Sometimes one can see very shallow cut Tanzanite stones which look big face on but result in a poor colour saturation .

Gary will also summarise the mining process, gem cutting, and export, as well as his experience of the ethical gem market in the UK and overseas.

 

Will 2013 be the year for ethical gems and jewellery to become mainstream ?

Rubyfair supplies orphanage

Will 2013 be the year that ethical supplies finally become the norm for jewellery supplies in the UK ? Last year has seen a surge in demand for fair trade gold and rubyfair.com has seen a major change in the way its ethical gemstones and it’s stance on ethical mining has been received. The ethical route rubyfair.com adopted from outset in 2008, with a mine to retailer approach for its ruby, spinel, sapphire and tanzanite was at the time unusual if not unique. Various gemstone suppliers had concentrated on either source , processing or community support but rarely had all these factors been taken into consideration. Thankfully a demand from the public plus increased  publicity in the press and through such shows as the IJL has brought this approach more into the mainstream. Lets hope this continues into 2013 and becomes the normal way both producers and retailers source their gemstones.
