Diamond Jewellery brands and manufacturers

What is Diamond?

Diamond is a solid form of the element known as Carbon which is the sixth element on the periodic table (if you want to learn how to earn money fast selling old diamond jewellery click here). The atomic structure of Carbon becomes crystal whenever it becomes a substance called Diamond cubic. When at room temperature Carbon becomes another solid substance call graphite which is the chemically stable form of Carbon. Diamonds are incredibly rare and are the purest forms of transparent Carbon . They are usually formed under tremendous pressure and depth, typically about 150KM bellow the surface of the Earth. Diamonds are made and brought to the surface of the Earth in Volcanos ( special types of rocks called kimberlites usually contain diamonds).

It can take up to 10 years to find a Kimberlite fragment and another 10 years to determine if it has enough Diamond deposit to become economically profitable (to find out how to make money on the stock market trading Diamond stock click here). Due to the fact that the atoms in Diamond are extremely rigid very few impurities can contaminate it with two exceptions being Boron and Nitrogen. Geologists often spend alot of time searching for and identifying potential sites that can be turned into Diamond mines. Diamond jewellery is the end product of most manufactured diamonds.

So how much is your pre-owned jewelry worth?

  • The Market: The value of your second-hand jewelry is dependent on market demand. Classic, timeless designs will likely sell more quickly and for more than lesser known designs. For the simple reason that classic designs are always in high demand.
  • Condition: Any damage or chips to precious stones will result in a lower offer as refurbishment costs will have to be factored in.
  • Rarity: Rare pieces or designs fetch higher prices due to low supply.


Always try to buy what is within your price range while focusing on the more important qualities like the cut quality of the Diamond within the jewellery.
