Coming back to types, Natural Diamonds can be categorized into 4 types, depending on the impurity levels.

  • 1a – It is the most common form of Diamonds and contains about 0.3% of Nitrogen. It absorbs blue light and so are generally light yellow or brown in color.
  • 1b – They are very rare in nature, about 0.1% of total. In them the nitrogen atoms occur isolated throughout the carbon lattice. In general have a more intense color than Type Ia diamonds, absorbing green as well as blue light. They can appear yellow, orange, green or brown in color.
  • 2a – They contain very negligible amount of impurities and are considered purest form of Diamonds. These are generaly colorless.
  • 2b – They occour very rare and may contain even lower concentrations of nitrogen than 2a. But they contain boron impurities at the atomic level, because of which they are generaly bluish in color. They constitute about 0.1 percent of total

Other than natural Diamonds, diamonds can be synthesized too. Two of the methods used are High Pressure High Temperature Synthesis using graphite and another growth technique called Chemical Vapour Deposition(CVD).

So thats all we had on types of Diamonds, we will be back with next post in this series soon.

Stamping – Creating personalized gifts

by francine on Apr.21, 2010, under Handmade Jewelry, Jewelry Making

Hand stamping is such a wonderful way to create unique, personalized gifts. There are endless styles of stamp choices for everyone’s style. There are also fun stamps like hearts, babies feet and even dog bones.

It is not that difficult to learn how to stamp but I would test it out first on scrap copper so you can test out the spacing and how hard you need to hammer. The great think about hand stamping is that part of the charm is that it is not perfect :)

So if you are looking for that wonderful personalized gift which will last a lifetime, a hand stamped, sterling silver gift is perfect!

Continuing with Diamond mines – with a value of about 9 billion USD, approximately 130 million carats (26,000 kg) of diamonds are mined annually. About 49% of them come from central and southern Africa, with Canada, India, Russia, Brazil and Australia being other significant sources.

  • As said above Africa is the largest source of Diamonds currently. Diamond extraction from primary deposits (kimberlites and lamproites) started in the 1870s after the discovery of the Diamond Fields in South Africa. Other than South Africa, diamonds mines are located in Angola, Botswana, Zimbawe and Tanzania.
  • Historically diamonds were found only in alluvial deposits in southern India led the world in diamond production from the time of their discovery in approximately the 9th century BC to the mid-18th century AD, but the commercial potential of these sources had been exhausted by the late 18th century.The current Indian mines include Golkunda, Kollur, Panna and Bunder project.
  • Russia is one other major source of commercially viable diamond deposits, mostly in Sakha Republic, for example Mir pipe and Udachnaya pipe.
  • Northern and Western Australia have good diamond deposits as well. Two of the big mines there include, Argyle and Merlin Diamond mine.
  • Some north western teritorries of Canada and Brazil also have commercial deposits used right now for mining.

Controversial sources (Blood Diamonds) – Some revolutionary groups in central and west African countries (which are politically unstable), have taken control over various Diamond mines. They use the proceeds of diamond sales via this process to find their operations. Diamonds coming illegally via such route are termed ‘Blood Diamonds’. In response to public concerns that their diamond purchases were contributing to war and human rights abuses in central and western Africa, the United Nations, the diamond industry and diamond-trading nations introduced the Kimberley Process in 2002. The Kimberley Process aims to ensure that conflict diamonds do not become intermixed with the diamonds not controlled by such rebel groups. This is done by requiring diamond-producing countries to provide proof that the money they make from selling the diamonds is not used to fund criminal or revolutionary activities.

So this was all about Diamond mines and sources, we will be back with next post on Diamonds for GEMS series sooner. Again, if you have any ideas, or you want to share anything, do email us at
