Call it what you will

We’re all used to the majority of gems being called by their name:
Diamond is diamond;

Opal is opal;

Turquoise is turquoise;

Even in it’s many different colours Topaz is still Topaz.

Emerald is emerald…well actually it’s Beryl…as is Morganite, Aquamarine, Heliodore and Goshenite!  What distinguishes each of these is the colour that the gem comes in (green, pink, pale blue, yellow and colourless respectively).

Ruby, well that’s actually a form of Corundum, called Ruby only when it is red, when it is pinky orange it is called Padparadscha.  All other colours of Corundum are called sapphires so you can find all kinds of sapphires, such as the green one below.

Tourmaline comes in a variety of colours and several of these have particular names too.  When it is red/pink it is Rubellite, green is Verdelite, blue is the fabulous Indicolite and colourless is Achroite.

Tanzanite is a form of zoisite, Morganite is a Beryl and they were both named by Tiffany and Co.

Amazonite is a type of Feldspar, as is Labradorite.  Incidentally Feldspar is the most prolific mineral in the Earth’s continental crust and can be found on Mars!  This is a good example of two types of mineral which are chemically related but clearly very different.

Quartz (the second most abundant mineral behind Feldspar) has another wide variation in colour, and many names or nicknames to go with it.  From the yellow citrine, to stunning purple amethyst (and of course the incredible ametrine is therefore part of this family).

Another variation is green quartz, sometimes referred to as green amethyst although if we were going to be strict about it that’s not it’s real name!  So we are going to go with the official Prasiolite, and here’s an example:

However the quartz pseudonyms don’t stop there, even more strangely Chalcedony (see ring below), Agate, Onyx, Jasper, Tigers Eye, Aventurine and Carnelian are all types of quartz that you might not guess from the name!

Smokey Quartz

 

Of course the feminine pink of rose quartz to the stunning brown hues of smokey quartz (ring above) and the fascinating Rutilated Quartz are also, more obviously part of the family.

Another slight confusion may arise when considering the names of gems in that often the gem quality variation of a type of mineral has a different name to the non-gem form, Csarite/Diaspore, Peridot/Olivine and Iolite/Cordierite by way of example.

 

Call them what you will, they’re all beautiful to us!

Does it have to be a diamond…?

Whilst there are many different colours of diamonds (which we’ll come onto in a different post) we’re going to look specifically at alternatives to the colourless diamond.  Common replicas include Cubic Zirconia, Moissanite, Petalite, Zircon and Topaz.  For even cheaper prices clear glass or acrylic is often used in high street jewellery.  These can all be found in incredibly clear and brilliant examples, they’re cheaper, many look similar, so how can you tell what is real?  Take the well known crystal brand Swarovski, this beautiful necklace (below) is stunning in many different lights, can you really tell that it’s not diamond; Wedding necklace and if you can does it matter?  In the cases of white Zircon, Topaz and Petalite, among others, you’re still getting a real gemstone, similar mining processes and cutting, but paying nowhere near the price of a diamond.  In any event to be fair can anyone really tell whether the rock around your neck is actually synthetic crystal or diamond anyway. Disadvantages of the alternatives So the obvious disadvantage of anything that isn’t diamond or one of the other really desirable gems is that it is likely to lose value, a real diamond is more likely (but not guaranteed) to gain in value over time, particularly good quality gems which are well looked after.  However, turning this on its head of course you probably won’t have paid anywhere near as much for a moissanite or CZ so does it really matter, to each their own. The other obvious disadvantage is that unless you’re wearing a diamond you are not wearing one of the hardest gems known to man…this could make your item easier to scratch or damage…you might not be able to use it to carve your name onto furniture… On a serious note each gem (real or synthetic) has different refractive/fluorescence and brilliance or sparkle.  This is where the real trick lies in trying to distinguish real from fake but in reality without close examination it’s unlikely that even an accredited jewellery professional is going to argue if you tell them your CZ is a diamond. There are also advantages to none diamond pieces, unless you’re particularly precious about your precious gems, synthetic or less pricy gems means you can afford either bigger pieces, or more items than you might be able to with real diamonds.  They can look just as stunning (I wore CZ on my wedding day so no arguments please, but cue an opportunity to flash some wedding bling!) Wedding bracelet and chances are most people you pass in the street won’t be able to tell.  After all how many of us have spent our journey to work staring at someone’s engagement ring wondering whether that giant rock is real or not…?! Ooh more importantly this means it’s more difficult to tell if that rock he got for you is real…hmmm that’s when it’s good to know a gemologist 😉
