Blue Diamond – Everything you need to know before Buying

Blue diamonds are very rare and natural beauty for many centuries. They are found in countries like India, Brazil, Indonesia, and South Africa. In India, they are found in the Kollur deposits.

The famous 112-carat great blue diamond is a classic example of these diamonds, which was cut into a 45.52 carat Hope Diamond. It is extracted from the Kollur deposits.

The color of the diamond is due to the presence of a chemical element called boron. The shades of the blue diamond vary with the presence of tint of this blue color mineral.

In such a means, the shades of these costly stones naturally occurring are ice blue, sky blue, and ocean blue. These stones with a slight tint of this blue color are ice blue diamonds.

Sky blue diamonds are fairly brighter with little more tint than the ice blue diamonds. Ocean blue is the darkest of the three shades; it is deep blue with a rich tint.

An ice blue diamond begins with a white polished diamond and so considered very expensive.

Comparatively, ocean blue diamonds begin as a brown diamond-shaped and are not as expensive as the ice blue ones, but are reasonably medium priced.

Tips to choose a blue diamond:

While purchasing the blue diamonds,

  1. Choose how important is the originality of the color of diamond to you. These stones with original blue color are rare and highly expensive.
  2. Many diamonds are artificially treated under various temperatures and pressure conditions, though these are allowed practices and does not degrade the value of these stones.
  3. Determine whether to get stones loose or buy them as a part of jewelry.
    Caring for your budget is very important. Even a small variation of shade or tint of color may cost you a fortune. Color diamonds such as blue are very costly compared to colorless diamonds. So choose the expenses carefully and then think of spending the rest in carat, size, and other values of diamonds.
  4. The next thing to remember is to decide the place where to get them. Getting them from authorized dealers will cost more than getting from a discount seller who may not provide adequate documentation.

While viewing and choosing the blue diamonds

Choose one with a “fancy” color that matches well with your taste and selection.
Choose the diamond by viewing it in various different light settings because dealers prefer an atmosphere where their product is at its best.

Get a mirror to your side and see it while choosing which jewelry matches your skin tone.
Compare these beautiful stones with different shapes. For example, the ones with round and square-cut reflect more light than the ones with the rectangular cut.
