Jewellery expertly crafted from diamonds and precious gems has been worn by kings, queens, and royalty from many cultures throughout history. It was a sign of wealth and status to wear jewellery and your finest clothing when making a public appearance. Following the style of ancient royalty, this list of the 10 most expensive pieces of jewellery ever made includes the world’s most expensive gem, the Hope Diamond. This beautiful diamond necklace is one of the most treasured items in the world. Many of the items listed here have changed owners many times but are still in existence today to showcase the craftsmanship that made them worth millions.

Diamonds are one of the hardest substances known to man. That is why many high-tech lasers use them for precision cutting instruments. It takes years of heat and pressure to create a beautiful gem from a lump of coal. Diamonds are made up of carbon naturally present in layers of the earth (90 miles below the surface) and are exposed to extreme heat and pressure over a long period. It takes millions of years to form what we now call diamonds. They are as old as the earth itself and partly what makes them worth so much money.

Jadeite is one of the rarest forms of Jade on earth. It is created from mesomorphic rock and intense pressure beneath the earth’s surface, much like diamonds. Ancient axe heads and beads made from Jadeite were discovered in Northern Italy. It is an old stone worthy of belonging to the Cartier Collection of jewellery. Not technically a piece of diamond jewellery, but it has diamonds in the clasp, which makes it a good addition to this list.

It was owned by the daughter of Woolworth’s founder Barbara Hutton, who was a jewellery collector herself owning several pieces of historical jewellery like the Marie Antoinette Pearl Necklace and the Romanov emeralds. She commissioned Cartier’s to add the ruby and diamond clasp that contrasts against the deep green Jadeite beads for a stunning necklace.

#10 The Hope Diamond -$200-250 million

Now for the number 1# most expensive piece of jewellery in the world, the Hope Diamond concludes this list at a price tag of $200 million dollars. A little known fact about the diamond is that it is the true-life piece that was the subject of interest in the movie “Titanic.” Although the pendant worn by actress Kate Winslet in the film was a sapphire, the story about the stone belonging to King Louis XVI and carrying a curse was in reference to the Hope Diamond.

The diamond was stolen twice during its lifetime, and a curse was put on it to cause anyone who possessed it to suffer bad luck. It was owned by 17th-century French merchant, Jean Baptiste-Tavernier, who then sold it to King Louis XVI. Everyone who came in contact with the stone suffered bad luck or untimely death. For the King, his children and grandchildren died young, and the King himself passed away from a terrible infection. It was passed down to his successor and his wife, Marie Antoinette. Of course, everyone knows how that story ends. So maybe there was some truth to the “curse” after all. After many owners and several mysterious deaths, it was finally acquired by the National Museum of Natural History where it resides today.

#1. Identifying a fake diamond from a real diamond

Given the high market value of diamonds and how they are one of the most sought-after gemstones, it’s not surprising that there are many replicas or fake stones that are in circulation. Be it for security reasons or simply a way to make a quick buck, fake diamonds are a reality and it is important to know how to distinguish them from the real ones.

#2. Identifying a real mounted diamond

Some excellent diamond imitations have successfully fooled even the most expert gemmologists, therefore using only your eyes to determine whether a diamond is real or not can be really tricky, but not impossible.

If a diamond is mounted, you would be unable to see through to its bottom if the diamond is real.

The reason being the way the light travels through the many facets of the gem.

Place an unmounted diamond face down upon a newspaper, if you’re able to see the text clearly, then there’s a problem.

#3. The diamond reflection test

A diamond’s reflection tells a lot about it. A real diamond will reflect in shades of grey. If you happen to see sparkling rainbow colors, the diamond is very likely to be a fake one.

#4. Testing a diamond at home

The density of a real diamond is extremely high, due to the immense pressures required to create them in the earth’s crust. Therefore the water test would show whether your stone matches that level of density.

You can use the following simple test to find out if a diamond is real – or not.

Find a medium-sized drinking glass and fill about three-quarters of it with water. Then, drop the stone carefully into the glass. If the gemstone sinks, the diamond is real. If it floats on the surface of the water, the stone is fake.

#5. The scratch test

This test is one of the easiest ways to test a diamond. All you have to do is simply scratch your stone against a mirror. If the stone in question is hard enough to scratch the mirror, it is most likely a real diamond.

In recent times this has become a more difficult test. A number of strong and durable materials are being used to make fake diamonds; therefore, this method is now less reliable.

#6. Heat resistance

A glass will easily shatter into pieces when it’s brought in close proximity to a heat source. On the other hand, an original diamond would be left unscathed.

#7. The fog test

Breath on your stone. Due to the moisture and heat from your mouth, a light layer of fog will form on the diamond. If the stone clears right away, it’s real. If not, then it’s fake.
