Have you ever own a piece of diamond or diamond Jewelry?           Do you know where
are they coming from and why are they so valuable?
Let’s have a journey to expose the nature and secret of diamond.


Atomic structure & physical property

Do you know diamond is actually carbon, sharing the same element with graphite?
Diamond is an allotrope carbon.      A carbon atom is connected to 4 other carbon
atoms to form a tetrahedral 3 dimensional structure.        It is the hardest natural
elements known in the world.         As well, diamond is has the highest thermal
conductivity. This is the reason why diamond is used as main components in the
cutting and polishing tools.   During the normal cutting process, huge amount of heat
are generated in a very short period of time, if heat is not transmitted away
immediately, the tools will be over-heated and damaged.    Since diamond is hard, it’s
good for cutting, it has high conductivity transmits heat away in very short period of
time, it makes diamond an excellent component for cutting dies.


Diamond as a gemstone


Diamond has high optical dispersion.     This makes diamond a beautiful luster as it
effectively disperses lights of different colors that we commonly called it fire and
sparkle. High optical dispersion, great mechanical properties, combined with its
scarcity makes diamond a very valuable gemstone.        Besides, diamond jewelry is
suitable for daily wear as it has high scratch resistant and is also good to wear in
nearly all occasion.
Can diamond be synthesized?




Scientists suggested diamonds are naturally produced at high temperature and
pressure hundreds of miles down underground.     It’s possible to produce diamond in
laboratory, however the cost is super-high and so, it is worth to own a piece of
diamond or diamond jewelry.


Diamond Supply


Annually there is around 60,000 pounds of diamond are mined, and about 200,000
pounds of diamond are synthesized.   About half of the world jewelry is supplied by
Central and South Africa. Others are mainly supplied from Canada, India, Russia,
Brazil and Australia.


Have fun!
