And the most dominating factor, is of course the play of colours which just surge the beauty and elegance when depicted under the bright rays of the sun.

As far as colour combos and variety is concerned, silicon jewelry falls no short to give a nerve-racking competition to opal jewelry. however, the colour of silicon jewelry usually depends upon the manufacturing process as well as the natural occurrence of the stone.

The most popular hues of silicon jewelry in the market are:

  1. Transparent Silicon: With a mystic and alluring crystal-clear beauty and high reflection, these clear or transparent silicon lends a glass like appearance when the light passes through their crystal.

2. Clarity

Opal is basically a hydrated form of silica with a comparatively high-water content that could range from being around 6%-20%. Moreover, it can be in a crystal-clear form, with almost no inclusions and impurities, lending a beautiful and flawless view.


In some cases, it is also quite common to see translucent to opaque variety of opals. However, the most cherry-picked as well as the treasured piece of opal is the one that has a completely transparent and crystal-clear surface which allows the light to depict a natural play-of-colours.

Besides, the degree of clarity and transparency is also affected by other characteristics of opal like its colour and type. Take for example, a black opal with a lavender to dark-wine colour tone would appear the best when complimented with an opaque surface, with a mystic and alluring colouration on its surface.

On the other hand, silicon jewelry being an artificial jewelry alternate, the clarity and transparency is usually determined by the functions to which it is exposed to during its manufacturing process.

In most cases, silicon jewelry, like that elegant and stupendous silicon necklace comes with a high level of transparency with almost zero degree of scope for inclusions and impurities.

This is so because by its very nature, silicon is a quite transparent material. So, it is quite obvious that silicon jewelry usually has an excellent clarity, sometimes as flawless and clear as a shining crystal.

However, the patterns and designs set by the gemstone jewelry supplier also influence the degree of clarity. For instance, if there are a lot of minute variations and designs included within the crystal of the jewelry, then it may surely reduce the clarity of the stone to some extent. Without compromising the beauty and attractiveness of the jewelry.

3. Durability

For opal jewelry, hardness is the only factor that could present a potential hindrance to the wearer. With a mere hardness level of 5.5-6.5 on the Mohs scale of hardness, it can’t withstand a rough bang with a hard surface. Even if exposed to water for a prolonged period of time, the crystal might appear cloudy or dull.

While storing your long stud opal earrings or opal bracelet, make sure to pack them separately in air-tight plastic bags to avoid any potential breakage or damage.

The hardness of silicon varies depending on the type and shape of silicon. Crystalline silicon, the type of silicon used in electronics and solar panels, has a mineral hardness level of roughly 7 on the Mohs scale. This means that, in comparison to many other materials, it is relatively durable and scratch-resistant.

Amorphous silicon, on the other hand, which is utilised in thin-film solar panels and other applications, has a lower hardness level and is more prone to scratching and damage. Amorphous silicon’s exact hardness level varies based on its composition and production technique.

4. Lustre

Opal jewelry would usually have a vitreous lustre with a glassy and reflecting surface.
