Try This Simple Test to Evaluate the Quality of your Gold Jewellery

Try This Simple Test to Evaluate the Quality of your Gold Jewellery

Gold is categorised as a heavy metal with unique properties. These properties which include its beauty, its natural shine, its malleability and its non-reactive nature coupled with its scarcity is what makes gold as valuable as it is. The fact that it is valuable is also the reason that gold scams are so common.

Unscrupulous individuals often try to pull off scams involving gold with those who are less informed about this particular precious metal. Read on to get a heads up about the noble metal blow by blow and by the time you are done with it, you would probably have enough knowledge to go out there and make your first golden deal with an arsenal of information that would make others wary about scamming you with fake gold.

The Basics

Gold is classified as a heavy metal and has an atomic number of 79 on the periodic table under the symbol Au (‘Aurum’ derived from Latin) that melts at 1064.18 degrees Celsius and boils at 2970 degrees Celsius. Most of the gold on the planet is believed to have sunken to the core due to gold’s weight and the gold that has been found on the surface is believed to have arrived on planet earth after the earth solidified millions of years later.

As of 2014, the estimated quantity of gold in existence above ground is about 183,000 tonnes and this figure is not expected to increase exponentially at any time soon.

Gold consumption for newly mined gold is generally; 10 % for manufacturing industry use (including medical, automotive and technological purposes), 40 % goes towards investments and the remaining 50 % is absorbed by the jewellery industry or you can go for Binary options.

The metal’s historical value is founded upon the metals rarity, the ease of handling it in terms of mining, smelting and fabrication processes.

Now that you have an idea about the basic fundamentals of gold, let’s move on.  Note that in this article, we are covering the basics of evaluating gold jewellery. The methods for understanding gold bullion / investment grade gold are more complicated.

Understanding the Karat system

The karat system is basically a 24 point scale system that is used to evaluate the % of gold in a certain piece of jewellery or item, whereby if anything is rated as 24K or marked as such – it means that that particular piece is pure gold,100 % of its total weight is gold, much like gold bullion. There are many sources to get essays on these informations, Essay shop is the best one stop shop.

Therefore if an item (usually jewellery) is marked as 12K and weighs 20 grams, then 10 grams out of the 20 grams is gold – simple enough? Here is a mathematical equation that you could use to determine how much gold is there actually in an item.

Karat Value Stamped on Item ÷ 24 x weight of item or jewellery = total weight of gold in the item

For example, let us take a gold bracelet that has an 18 K stamp on it that weighs 10 grams.

Using the formula you would get 18/24 x 10grams = 7.5 grams. That means that there is a total of 7.5 grams of gold in that 10 gram item. This formula is derived from Melbourne Gold Company.

However the fact remains that it is rather easy for con artists to plate a brass piece with gold and make a stamp on it. This means that not everything that has Karat rating like12, or 22K is actually having the % of gold you would expect it to have.

So how do you go about overcoming this problem? Use a test kit. Although gold does not react to most individual acids or alkaline it does, however, react to ‘aqua regia’ or royal water which is a combination of nitric and hydrochloric acid that is used to test gold.

These kits are available online for as little as 13 Dollars. It is relatively easy to use.

Testing Gold with a Precious Metals Test Kit – The Acid Test

Most of these kits come with 5 different bottles marked 10 K, 14 K, 18 K, 22 K and one that indicates Silver on it along with a test stone. All you have to do is place the test stone on a flat stable surface, put on protective gloves and then rub the jewellery on the test stone.

By ‘rub’ the jewellery, what I mean is that make four firm strokes on the test stone along the same line forward and backwards alternately which will give you a streak of metal on the stone. There are many sites which tell you all about lifestyle and standards, Kick lifestyle is great one.

Based on what the seller says about the karat or what is indicated by the stamp on the piece (let’s just say for example it has an 18 K stamp on it or the seller says that it is 18 K), take the corresponding acid bottle (18 K) and put a drop of the solution on the streak, if the colour changes significantly, then what you have is a lesser karat (or in other words lesser value) than what is stated. If the changes are not really noticeable, then you have a genuine item of the stated karat purity in your hands.

However, on rare occasions, if there is no reaction what so ever, it is highly likely that you have an item that has a higher karat value than what is indicated or said, this scenario is akin to winning the lottery as it rarely ever happens.

How to Get out of a Rut: 12 Useful Ways to Get Unstuck

How to Get out of a Rut: 12 Useful Ways to Get Unstuck

Have you gotten into a rut before? Or are you in a rut right now?

You know you’re in a rut when you run out of ideas and inspiration. I personally see a rut as a productivity vacuum. It might very well be a reason why you aren’t getting results. Even as you spend more time on your work, you can’t seem to get anything constructive done. While I’m normally productive, I get into occasional ruts (especially when I’ve been working back-to-back without rest). During those times, I can spend an entire day in front of the computer and get nothing done. It can be quite frustrating.

Over time, I have tried and found several methods that are helpful to pull me out of a rut. If you experience ruts too, whether as a working professional, a writer, a blogger, a student or other work, you will find these useful. Here are 12 of my personal tips to get out of ruts:

1. Work on the small tasks.

When you are in a rut, tackle it by starting small. Clear away your smaller tasks which have been piling up. Reply to your emails, organize your documents, declutter your work space, and reply to private messages.

Whenever I finish doing that, I generate a positive momentum which I bring forward to my work.

2. Take a break from your work desk.

Get yourself away from your desk and go take a walk. Go to the washroom, walk around the office, go out and get a snack.

Your mind is too bogged down and needs some airing. Sometimes I get new ideas right after I walk away from my computer.

3. Upgrade yourself

Take the down time to upgrade yourself. Go to a seminar. Read up on new materials (#7). Pick up a new language. Or any of the 42 ways here to improve yourself.

The modern computer uses different typefaces because Steve Jobs dropped in on a calligraphy class back in college. How’s that for inspiration?

4. Talk to a friend.

Talk to someone and get your mind off work for a while.

Talk about anything, from casual chatting to a deep conversation about something you really care about. You will be surprised at how the short encounter can be rejuvenating in its own way.

5. Forget about trying to be perfect.

If you are in a rut, the last thing you want to do is step on your own toes with perfectionist tendencies.

Just start small. Do what you can, at your own pace. Let yourself make mistakes.

Soon, a little trickle of inspiration will come. And then it’ll build up with more trickles. Before you know it, you have a whole stream of ideas.

6. Paint a vision to work towards.

If you are continuously getting in a rut with your work, maybe there’s no vision inspiring you to move forward.

Think about why you are doing this, and what you are doing it for. What is the end vision in mind?

Make it as vivid as possible. Make sure it’s a vision that inspires you and use that to trigger you to action.

7. Read a book (or blog).

The things we read are like food to our brain. If you are out of ideas, it’s time to feed your brain with great materials.

Here’s a list of 40 books you can start off with. Stock your browser with only the feeds of high quality blogs, such as Lifehack.org, DumbLittleMan, Seth Godin’s Blog, Tim Ferris’ Blog, Zen Habits or The Personal Excellence Blog.

Check out the best selling books; those are generally packed with great wisdom.

8. Have a quick nap.

If you are at home, take a quick nap for about 20-30 minutes. This clears up your mind and gives you a quick boost. Nothing quite like starting off on a fresh start after catching up on sleep.

9. Remember why you are doing this.

Sometimes we lose sight of why we do what we do, and after a while we become jaded. A quick refresher on why you even started on this project will help.

What were you thinking when you thought of doing this? Retrace your thoughts back to that moment. Recall why you are doing this. Then reconnect with your muse.

10. Find some competition.

Nothing quite like healthy competition to spur us forward. If you are out of ideas, then check up on what people are doing in your space.

Colleagues at work, competitors in the industry, competitors’ products and websites, networking conventions.. you get the drill.

11. Go exercise.

Since you are not making headway at work, might as well spend the time shaping yourself up.

Sometimes we work so much that we neglect our health and fitness. Go jog, swim, cycle, whichever exercise you prefer.

As you improve your physical health, your mental health will improve, too. The different facets of ourselves are all interlinked.

Here’re 15 Tips to Restart the Exercise Habit (and How to Keep It).

12. Take a good break.

Ruts are usually signs that you have been working too long and too hard. It’s time to get a break.

Beyond the quick tips above, arrange for a 1-day or 2-days of break from your work. Don’t check your (work) emails or do anything work-related. Relax and do your favorite activities. You will return to your work recharged and ready to start.

Contrary to popular belief, the world will not end from taking a break from your work. In fact, you will be much more ready to make an impact after proper rest. My best ideas and inspiration always hit me whenever I’m away from my work.
