The Evolution of the Diamond In Fashion Trend

Saturday, June 15th, 2013

The Process Begins

Diamondscan only be formed under extreme geological conditions where the right amounts of pressure and heat can transform carbon into a diamond. These conditions only exist at 150km to 200km below the surface of the earth in the molten rock of the Earth’s mantle when the temperature is greater than 800 degrees Celsius and pressure is 50,000 times atmospheric pressure. It is in these deep depths that diamonds are created and exist until they are bought to the surface of the earth.

This happens through powerful magma eruptions which bring up the diamonds via kimberlite “pipes”. Like other igneous rocks, kimberlite was formed over the course of thousands of years by volcanic activity that occurred during the formation of the earth’s crust. Kimberlite is therefore located inside these former areas of volcanic activity, often near mountain ranges, in vertical shafts that extend deep inside the earth. Kimberlite pipes were created when magma flowed through deep fractures in the kimberlite rock.

These eruptions were short but many times more powerful than volcanic eruptions that happen today, pushing the diamonds and other rocks and minerals through the mantle and crust in just a few hours. According to geologists the first delivery of diamonds was somewhere around 2.5 billion years ago and the most recent was 45 million years ago. That means most of the diamonds that we see today were formed millions, if not billions, of years ago.. but that’s just a guess.

At the Surface

Once diamonds have been brought to the surface they can then be found in the host rocks that have brought them from the earth’s interior or in alluvial deposits. An alluvial deposit is formed when melt water and rain erodes mountains away and drags heavy and durable stones, such as diamonds, downstream to be deposited in a different section of the river or stream. Diamonds, being hard, are often found in alluvial deposits as they can endure the eroding effects of the water flow. Diamonds are found in alluvial deposits in diamond mines in places such as Botswana, Namibia, Canada, Brazil, Venezuela, Russia and Australia.

The Last Stage

Finally, before it gets to the jewelry store, a raw diamond needs to be cut down to a manageable size. Depending on the strength of the diamond this is done with either by hand, using diamonds to cut other diamonds, by phosphor-bronze blade rotating at about 15,000 rpm, or by a laser. This process is what gives diamonds their shape. Afterwards they are polished to create the diamond’s finished look.

The Best Diamond Engagement Ring

Thursday, June 2nd, 2011

A marriage proposal is a major event that will be remembered and talked about for the rest of your life. A lot of men have an elaborate plan for the time and place of the proposal and even rehearse lines to make sure everything goes smoothly. The same type of careful planning should go into ring selection and this article is going to give you some tips on how to buy the best diamond engagement ring.

The first thing you should think about is your budget. A salesman at a jewelry store will try to tell you that you should spend two months salary on an engagement ring. You really should spend whatever you feel comfortable spending and whatever you feel you can afford. When you have a budget in mind ahead of time it will be easier to stay within a comfortable price range.

To select a ring you should know about the four C’ s. Color, clarity, cut, and carat size. All of these will have an effect on the price of the ring. Some rings have a noticeable color and if this is the case the diamond will be less valuable. Clarity refers to the number of flaws or inclusions in the diamond. The fewer inclusions there are the more valuable the diamond will be. The cut refers to the reflective quality of the diamond and ranges from ideal to fair and poor. A higher-quality cut will reflect more light and give the diamond its brilliance. Carat refers to the size of the diamond. Most engagement rings are one carat.

In addition to the diamond you will have to select a setting. There are many choices available including prong, channel, cluster, and flush. The setting will determine the center stone’s height. You’ll also need to select a metal for the setting. Some popular metal choices are platinum, white gold, yellow gold, and titanium.

There’s a lot that goes into selecting a ring but if you want to know how to buy the best diamond engagement ring you should be familiar with your girlfriends taste in jewelry. After all the ring is for her. One tip is to be familiar with the jewelry she already owns. This will give you some clues to what type of engagement ring she might like. Is her jewelry simple or is it more flashy? Is it modern or does she seem to prefer the antique look? Another good way to find out what type of ring she might like is to comment on someone else’s engagement ring. She will likely comment on it as well and this is when you should be paying attention to get an idea of what she might like.

There’s a lot to think about when shopping for the perfect engagement ring. To help make it a little easier, plan your budget ahead of time, keep the four C’ s in mind, and keep your eyes and ears open for clues about the type of ring she likes. Follow those tips and you will surprise your future wife with a beautiful engagement ring that she will fall in love with.
