Neodymium Magnetic Jewellery

Compact and powerful, Neodymium has become the heavily used magnet in many kinds of magnetic jewellery in spite of its relatively higher price. None the less, the price you pay is economical when compared with the magnetic strength that has been packed within Neodymium products. Find more details below...

Neodymium or “Neo Magnet” as it is popularly known was introduced in 1984 but came into everyday use very recently. It is one of the few big magnets that have been considered safe to be worn over the skin. It is made from rare earth metal Neodymium mixed with Iron and Boron. Technically it is notated as “Nd Fe B” where Neodymium is around 75%. The price of Neo magnet is high due to companies registering proprietary rights over the production process.

Used as bracelet, amulet, choker and anklet in magnetic jewellery Neo magnet has several features that make it the most desired magnet in the world:

1. Light in weight but projects higher magnetic flux density at 12, 800 Gauss which is the recorded highest for any type of magnets so far. Hence a small size neo magnet is sufficient when we are looking for Gauss strength of 3,000 or below. Today, most magnetic jewellery is made around this figure in the gem & jewellery industry

2. It does not lose magnetism over the years and has higher resistance to external magnetizing fields. This we call as Coercive Magnetic Field Strength. Consequently that Neo magnet can be exposed to other magnets without ever losing its magnetic quality. If you walk through highly magnetised environment your magnetic jewellery made of Neo magnet does not suffer loss of magnetism

3. Though Neo magnet has less resistance to corrosion this can be offset by coating Gold , Nickel and Zinc layer over it. Of late, Epoxy resin coating is also used to add anti-corrosion capability

4. Neo magnet is somewhat brittle and has lower mechanical strength yet for purposes of magnetic jewellery making this does not pose much of a challenge

5. This magnet variety has fairly low operating temperature capability. Any operating temperature over 150 degree Celsius demands extra caution.

6. Cosmics of using neo magnet is the key plus point. Unlike other type of magnets the moment you touch Neo magnet you get the feel of it running through your veins. You get so elated and float with strength of power within you. Recommended by analyst as the best magnet to balance your energy flow Neo magnet is useful in many ways in health and wellness.

7. Before opting for Neo magnet, you have to assess your personal cosmics and then determine the necessary gauss strength along with the type of wear such as bracelet.

Ceramic Ferrite Magnetic Jewellery

Moderate price and equally moderate magnetic strength are the twin features of Ceramic Ferrite magnet. Both factors combined together have placed this magnet as the key bastion on which tons of magnetic jewellery is made globally.

Ceramic Ferrite is simply mixture of ceramic clay along with Iron powder and either of Barium Carbonate or Strontium Carbonate. In this blog I am talking about Ceramic Ferrite made with Barium Carbonate as a constituent alloy. Let me explain my point of view. Although the typology Ceramic Ferrite is used to refer to either of these two elements Barium or Strontium it would be better if we restrict Ceramic Ferrite to Barium Carbonate mixture only. The technical script for this Barium mixed magnet is given as Ba Fe 12 O19. Here are salient points of Ceramic Ferrite mixed with Barium for your reading:

1. Ceramic Ferrite is easily manufactured in various sizes and forms: round, square, rectangle, arc, triangle, horseshoe and much more. It can be subjected to multi type production processes including sintering, pressing and injection moulding. In gem & jewellery industry sintered one is very popular. Historically sintered Ceramic Ferrite was the precursor of modern magnets as it was introduced in 1960s as cheap and convenient alternative to metallic magnets that were too heavy.

2. This type of magnet is sought after by the gem & jewellery industry to mount magnets of different sizes and shapes. Widely used in several types of jewellery wear including bracelet, wrist band and wraps Ceramic Ferrite snugs in even minute jewellery.

3. Though the magnet has hardness of 7 at Mohs scale in its favour it is very brittle. As a result its mechanical strength is low. Never the less this does not create snags while fabricating magnetic jewellery.

4. Ceramic Ferrite has excellent anti-corrosion resistance. Therefore, no coating or plating is required.

5. As Ceramic Ferrite has lowest magnetic flux density among the type of magnets its use is fairly restricted to magnetic jewellery where the required Gauss strength averages around 1,500 Gauss.

6. It does not lose magnetism over the years and considered as the most popular permanent magnet sold at an affordable price. Moreover, it has fairly higher resistance to external magnetizing fields. This we call as Coercive Magnetic Field Strength. Ceramic Ferrite is ranked third after Neo magnets and Samarium Cobalt in this regard. At the time of production the resistance to external magnetizing capability can be tweaked to soft ferrite or hard ferrite. Soft Ferrite has relatively lesser Coercive magnetic field strength than hard ferrite. If you walk through highly magnetised environment your magnetic jewellery made of Ceramic Ferrite might suffer loss of magnetism depending on whether it is soft or hard ferrite and the level of ambient magnetic force surrounding you.

7. This magnet variety has higher operating temperature capability. Maximum operating temperature of 300 degree Celsius means Ceramic Ferrite can be easily fixed in various types of jewellery. However, at operating temperature of 460 degree Celsius it would lose magnetic strength altogether.

8. When you use Ceramic Ferrite you get positive cosmics in the form of balancing between and amongst competing forces within you. Outside this magnet can place you in a stronger position to resist pressure and deflect negative energy. As a cautionary remark I must say, selecting Ceramic Ferrite dictates that you do a thorough assessment of your personal cosmics and then decide what type of magnetic wear you should choose and the relative magnetic strength.

What is Hematite Magnetic Jewellery?

Natural Hematite is one of several mineral forms of iron oxide. It has no capacity to function as magnet. What is sold as Hematite Magnetic Jewellery is not Hematite at all. Read more….

You can surf the Internet to find plethora of sellers purveying “Hematite magnetic jewellery”. As you know, a piece of jewellery is magnetic only when it contains magnets. Lodestone is the only natural magnet. Others are man-made magnets such Neodymium.

Natural Hematite is mineral form of iron oxide (Fe2 O3) In fact this is simply iron. Slightly harder but much brittle than iron, Hematite is basically Ferro-magnetic meaning that it can be attracted by a matter that has magnetic field. Even this feature undergoes changes in certain circumstances resulting in the phenomenon known as “antiferromagnetic”. Even though this type of structural change is subject to discussion and debate it is commonly agreed that Hematite is not naturally magnetised and has no capacity pull matters such iron, cobalt or nickel towards it. Furthermore, Hematite cannot be artificially magnetised either by mechanical process without altering the chemical component of hematite iron ore.

What is sold as Hematite magnetic jewellery is basically Hematine an artificial substance composed of Barium, Strontium Ferrite (Ba Sr Fe12 O19). This substance has strong magnetic field and without any doubt can function as magnetic jewellery.

So when you buy next time Hematite magnetic jewellery, be careful to ask the right questions whether it is natural Hematite or artificial Hematine.

Lodestone as Magnetic Jewellery

Lodestone is the one and only natural magnet used in magnetic jewellery. The saga of Lodestone is interesting. Found by chance, it started the study of magnet and magnetism. More than that, it has proved to be an effective anti-dote to several ills when used as magnetic jewellery. Read more…..

The legend says Magnes a Greek shepherd who lived in Northern Greece Millenniums ago, noticed one day that the nails of his shoes got stuck to earth beneath his feet. He dug the ground below and discovered a rock that has caused this phenomenon. Aptly dubbed as magnetite, the new - found Lodestone led human race to coin words such as magnet and magnetism in relation to the drawing power of magnet over iron.

Lodestone, often black and brownish rock is actually a type of magnetite with the capacity to act as natural magnet. All other varieties of magnetite have no such capacity. The word magnetite is a misnomer as magnetite in general gets attracted to magnet due to its iron content. Then the question is why Lodestone is different from the other magnetite. Very recently researchers found the clue for the missing link. Some of the magnetite that received lightening got naturally magnetized and was thereafter christened as Lodestone. That is enough for our study of magnetism. Let us turn to see how Lodestone came to be used.

Greeks, Romans, Egyptians, Arabs, and Chinese have used Lodestone for multitude of purposes. Greeks were the forerunner in identifying and using magical power of Lodestone. Thales of Miletus, a Greek Philosopher was the first to mention iron clinging onto Lodestone. Archimedes used Lodestone in attack on enemy ships with the aim to remove iron nails on the wooden planks that bind the ships ultimately sinking them. Pliny the Elder of Rome described magical power of Lodestone in healing and scaring away evils.

Cleopatra, Queen of Egypt used an amulet made from Lodestone over her forehead to preserve beauty. Chinese found dual use of Lodestone: on the utility side they developed the primitive compass with Lodestone to trace the northern direction for easy navigation. On the occult side they used it for divination and oracle.

Power of cosmics of Lodestone is remarkable. Those who wear it as pendant , amulet or in other suitable forms find they quickly align themselves with nature. They tend to understand issues and delve deep into matters that need to be resolved. Attracting new suitor or lover is generally attributed to Lodestone. Romans are the first to fabricate Lodestone magnetic jewellery to keep warring couples together. As marriage saver Lodestone brings warmth of friendliness between spouses who for valid reasons may try to go on separate ways. Improving relationship and balancing energies within are notable other cosmics.

Like in other gems & metals you must assess whether Lodestone is in fact necessary for you. Once you have zeroed in you have to find the convenient size of Lodestone that is necessary. The type of wear such as pendant or amulet is the next question to be answered. Finally whether you can use Lodestone as rock or tumbled one must be decided.

Magnetic has Double Meaning

We talk about a magnetic personality when we refer to someone who is so charming, charismatic and who captivates your attention not to forget of being so irresistible. In general you are drawn towards a magnetic person. However, in gem & jewellery the word magnetic is used to imply mutually opposite ideas. Read on……

The word magnetic is used in gem & jewellery industry in two sets of meaning. One is to imply that gems & metals can be attracted to any other external force such as a real magnet. For example, several types of Garnets including Almandine, Pyrope and Demantoid when placed within a magnetic field would be easily get attracted to this field. Similarly metals such as Iron, Nickel and Cobalt possess what we call magnetic properties that push these metals into the folds of any magnetic field.

This property of being drawn into a magnet is dubbed as “magnetic susceptibility”. In simple language we call this “being attracted to magnets”. The degree of being attracted to magnet differs from metal to metal and gem to gem. Some exhibit strong inclination to be picked up by magnet. Epidote and Magnetite are gemstones that possess strong magnetic properties. Iron is a metal that can be quickly grabbed by a magnet. These are classified as “Ferromagnetic”. Others carry fairly weak magnetic properties. Classified as “Paramagnetic” these metals including Platinum and Titanium show little enthusiasm in getting attached to a magnetic force. Hessonite and Grossular are couple of gemstones displaying weak magnetic ability.

Then there are gems & metals that are diamagnetic. This means magnetic force cannot draw these matters but instead expel them from the area of magnetic force. Bismuth, Cadmium, Carbon and Copper are the main minerals in this group; Sapphire and Zircon are notable gemstones in the diamagnetic category.

To add a twist in the meaning gem & jewellery industry, has introduced items that is magnetic in true sense of the word. A good example is magnetic jewellery made with real magnets. As you are aware a magnet carries magnetic force within itself enabling it to draw into its fold any matters that are susceptible to magnetic force. Needless to say, this magnetic jewellery attracts any matter that has magnetism within it. Most if not all these magnets are man-made from an alloy of two or more minerals. Ceramic Ferrite, Strontium Ferrite, Samarium Cobalt, Neodymium and Alnico are varieties of magnets used in the industry.

Do we have natural magnets in the world? Yes, Earth is embellished with a natural magnet in the form of Lodestone. It is the only mineral that acts as a natural magnet amidst all artificial magnets.
