Why invest in Diamonds 
Let’s define first what the qualities of a good investment are.   
An investment that retain its value unaffected by stock market crashes, inflation, or anything that cause currency to devalue.
An  investment that offers you some privacy from your finances being  scrutinized, There is no paper trail when you own 100 percent of the  asset.
An investment that requires no ongoing maintenance. 
An investment that no one person or organization has a monopoly on.
An investment which is easily transported and has an international value.
And surprisingly (or not) Diamonds qualified for all of the above.
By  looking at the historical price of Diamonds in the last year, you can  see that their strength is very clear, and nothing seems to affect them,  some diamonds did change, however they are not the investment type  (this point will be discussed more soon).
Secondly it offers you peace and tranquility, that your money is safe.
Investment  Diamonds are not like regular jewelry diamonds, they require no  maintenance, there is no warring risk, and they don’t take a lot of  space. 
Many  potential investors make a fair argument about investing in Diamonds  claiming that it’s relatively a new market that has no strong investment  background. 
There are many different approaches as to why it is that way.
First  of all, since the diamond industry began people always bought diamonds  as a family fund, maybe it wasn’t call investment but a family fund is a  type of investment.
Second  of all in order for a diamond to be a good investment, it has to be  bought in a good price (like any other good investment), it can’t be an  investment when one man or one organization owns 100% of that market,  you can’t have your invested money depending on one man’s bad day.
So  as the diamond industry began, it was in a way a one man show, which is  the first sign of a bad investment, DeBeers owned all the Diamond  mines, and the price was what they said.
Second  of all until the diamond made his way to the store, it pass 3 or 4  hands and hence lost its investment value (and nonetheless almost  everyone how purchase a diamond, considered it as an investment).
Now  a day the diamond industry is extremely far from being a one man show,  new diamonds mines are discovered every year in different countries and  different condition, more competition exists and they all want to sell.
