For buyers without an indepth knowledge of gemstones, iolite would seem to be quite similar to tanzanite and many people infact mistake iolite for tanzanite. Iolite stones are a gorgeous bluish violet color and lighter shades of iolite look similar to tanzanite. However, iolite is not tanzanite and has a beauty of it's own.
Gem quality iolite stones are not exactly cheap but they are priced much lower as compared to tanzanite gems. Here are a few important features and facts about the iolite gem stone.
(a) The iolite gemstone is quite durable and strong. It has a hardness 7 to 7.5 on the Moh's scale of hardness. This makes the iolite stone very suited for jewelry making. As far as durability of the gemstone is concerned, iolite is more durable than tanzanite.
(b) Iolite exhibits an important property called 'pleochroism'. You can observe this if you hold an iolite gem stone and view it from different sides. You will see different colors from different angles. From one side the iolite gemstone will look a rich bluish violet color and from the opposite side it could appear pale and almost colorless! As interesting as this phenomenon can be, it poses big hurdles for gemstone cutters. This is because the iolite stone needs to be cut at the perfect angle so that it shows it's best color from the top. This is the reason why only skilled craftsmen can bring the best out of an iolite gemstone.
(c) It is not very hard to find gem quality iolite stones in large sizes that can go up to 4 or 5 carats per piece. However these large iolite gemstones are getting to be rarer as demand increases. The rising prices of tanzanite is one reason for iolite gems getting to be expensive too.
(d) There is an interesting fact about iolite stones and that concerns the price of the gemstone. We already mentioned above that iolite is more durable as compared to tanzanite. This means that iolite gem stone jewelry has better longterm durability as compared to tanzanite jewelry. Why then is iolite cheaper than tanzanite? The reason is that tanzanite was introduced to the jewelry world with a mind boggling marketing blitz. This was what initially led to the price rise of tanzanite gems. Subsequently, a natural disaster in the main tanzanite mines at Tanzania reduced the output of tanzanite and further pushed up prices. However, the marketing hype that brought Tanzanite to the gemstone trade is still believed to be the main reason for the high price of tanzanite gems.
(e) The iolite gemstone is also referred to as the 'gemstone of the Vikings' and this has an interesting story attached to it. It is believed that the gemstone was used by the Vikings to help them navigate the high seas. The Vikings made use of the iolite stone to point them towards the sun. This was very important especially when they were far off from the coast and the sky was overcast with clouds.

Diamond And Gem Stone
This is one that lots of people have to deal with. I want to say first that I am glad you have an aquamarine! This makes me smile in a sentimental and special way. Why? Well, with so much blue topaz on the market today, the wonderful aquamarine has almost faded in the public eyes. Unfortunately, many do not even know about this much more valuable and beautiful gemstone. In years past, the aqua WAS the stone of choice for those special shades of blue nature makes. Aquamarine is a superior stone in all aspects to the irradiated blue topaz, a stone not naturally the rich blues in nature.
First of all, most jewelry shops do not have the capability to recut chipped gemstones. Some of this depends on the cut of the stone to start with, whether a cabochon(round top, like an opal or onyx might be cut) or faceted as with diamonds, rubies and other stones with little faces (the facets) on the surface. The person who cuts gemstones does the work called 'lapidary' or stone cutting. This work requires the cutting and polishing equipment needed for gemstones. Almost all stones must be worked with tools the jeweler simply does not use for working metals.
Stones are much harder than metals and require special and sometimes very specialized machines to work the gem, whether in cutting a gem from a piece of rough material from the earth or in repairing a chip in a stone already cut. While many folks do cut and polish cabochons(rounded tops without facets), the number greatly lessens when looking for those who do facet cutting. The equipment is very different since each individual facet is cut one at a time, through different grades of cutting from rough abrasives to the final polish.
What do most jewelers do? When a chipped stone needs repair, the jeweler generally sends the stone to a lapidary craftsperson. This usually means sending the stone to a company where the work may be done. Sometimes, the jeweler might have a local connection to either a professional or amateur(some are the best going!) for the repair work. The cabochon work is easy and more locals can do this work. For faceted gems, having a local cutter is not common and most stones are shipped to a factory offering the service.
What work is needed? Some companies offer to cut the gem stone for you. On some websites they show you what kind of cuts that they can do. When you see line drawings of the 'diamond' they want to sell. Using the line drawings, you can get an idea of how difficult it might be to repair the chip in your aquamarine. It all depends on the location of the chip! The middle of the stone, between the top(crown) and the bottom(pavilion) is called the girdle of the gem. If the chip is here, repair is relatively simple for a small chip and will not affect the rest of the stone in a noticeable way.
If the chip is higher on the stone, say on or between a couple of the facets on the crown, the repair is more difficult. Why? Look at the drawing(or at your aquamarine) and you will see the faces line up and meet each other. To repair a chip on one of the higher facets will mean cutting and polishing the stone down deep enough to remove the chip. This will change the face where the cutting is done and the facets will not line up as before.
To do the job properly, often the entire top(crown) of the stone will need to be re-cut. This means all facets are re-cut and polished so they all line up as before. This is done to prevent one large repaired face from messing up the arrangement and standing out easily to the eye.
How the repair is done depends on the location of the chip and whether the stone is faceted or a cabochon cut. Then, where and how well the work is done depends on the contacts the jeweler has. To find a jeweler with in-house lapidary service is a rare find, indeed. Be sure to ask if the work is done in-house or sent to a cutter. Ask for an estimate before having the work done. Ask if the repair will change the over dimensions (width and length) of the stone since that will affect how it fits back into your jewelry mounting.
Ask if the cutter can give you at least an idea of how much stone must be cut away to do the repair. Asking these questions can kind of give you an understanding of how the stone might look when they are done with it. But sometimes it is good to ask these questions that way you can find out if taking your stone to this one person is a good thing. You can always go around to all of the jewelry stores and ask them the same questions and when you get home find out which one is the best for you.
