Diamond is the hardest known natural material. Its hardness and high dispersion of light make it useful for industrial applications and jewelery of course.
They make excellent abrasives because they can only be scratched by other diamonds, Borazon, ultra hard fullerite, or aggregated diamond nanorods, which also means they hold a polish extremely well. Approximately 26,000 kg are mined annually, with a total value of approximately £ 4.4 billion, and about 100,000 kg are synthesized annually.
The name diamond comes from the Greek adamas which means invincible. They have been treasured as gemstones since their first use as religious icons in India and use in engraving tools also dates to early human history. The popularity of diamonds has risen since the 19th century because of increased supply, improved cutting and polishing techniques, growth in the world economy, and innovative and successful advertising campaigns. They are commonly judged by the "four Cs": carat, clarity, color, and cut.
Roughly 49% of diamonds origin from central and southern Africa, although significant sources of the mineral have been discovered in other countries like Canada, India or Australia.
Although diamonds are considered the most prized of all gemstones, many other precious stones are used for jewelry, but they will never have the same effect as a beautiful diamond and diamond rings will always be very popular, especially when they are diamond engagement rings.
Representing the past, the present and the future, the three stone diamond rings are just the perfect for your beloved. These diamond rings represent perfectly all that has made each partner what they are today, the present moment that they share, and the future into which they now walk together. The three stones in three stone diamond rings commemorate the eternity of your relationship. Given popularly as anniversary gifts, three stone diamond rings are also exchanged as engagement rings.
