Basic information about the gemstones we sell at Northgate Jewellers -     Coming Soon


 Amber is the fossilized resin of ancient pine trees.  Warm to the touch and very light to wear, amber has been worn as jewellery for thousands of years.  It comes in many colours, ranging from a very pale yellow, through orange, red, brown, black and green.

Because it comes from living material, it is called an "organic" gem.  Like other organic gemstones, amber is delicate; it is very soft and is easily damaged.  It can be melted by even low heat and some solvents will dissolve it. 

Rings & Bracelets:  For occasional wear only - amber is very easily scratched which will dull the surface.

Pendants & Brooches:  Normally OK

Earrings & Necklaces:  Take care that the amber is not in contact with perfume or hairspray which can easily damage the surface.  RULE: Jewellery "on last and off first " to minimise the risk of accidently spraying with perfume or harispray.




Amethyst is the name given to the purple variety of quartz.  (The so called "green amethyst" is simply a marketing ploy to sell green quartz!).  Amethyst occurs in several places in the world, and can vary in colour from pale lavender to the deepest purple.  The best quality amethyst is very clear and deep purple with flashes of red.  As it is as hard as the quartz which forms a large part of dust, it is fairly resistant to scratching, but diamonds, rubies and sapphires are all much harder, so store your amethyst away from these.  Also, UV light can cause amethyst to fade over time, so keep it in the dark when it is not being worn.  Very pale amethyst is sometimes heated up in the hope that it will turn yellow to form citrine, the yellow variety of quartz.  Most citrine on the market today is produced this way.
