Raw Crystal Transparency - Important Points To Know
In mineralogy, diamond (from the ancient Greek – adámas “unbreakable”) is an allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centred cubic crystal structure called a diamond lattice.
Most natural diamonds are formed at high-pressure high-temperature conditions existing at depths of 140 to 190 kilometres in the Earth’s mantle.
Were you aware that only about 20% of all diamonds mined are considered (and cut as) gemstones?
Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years (22% to 73% of the age of the Earth). They are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites.
The hardness of the stone contributes to its suitability as a gemstone. Because it can only be scratched by other diamonds, it maintains its polish extremely well. Unlike many other gems used in handcrafted jewellery, it is well-suited to daily wear because of its resistance to scratching—perhaps contributing to its popularity as the preferred gem in diamond solitaire engagement rings or diamond wedding rings, which are often worn every day.
As a product of nature, each and every diamond is different. We understand there are variances in Carat Weight, Body Colour, Clarity Imperfections, and Fluorescence.
Although many (almost everyone), believe that apart from these unique features (that are marketed and documented by grading laboratories) that all stones are the same… NOT TRUE!
What Is Raw Crystal Transparency – RCT™?
Transparency is the material property of allowing light to pass through a loose diamond.
A diamonds lattice is what enables light to passage through its crystal body so efficiently and is one of the key factors when deciding whether it will be used for industrial purposes, or as a cut gemstone in a diamond solitaire engagement ring or diamond wedding ring.
Diamond transparency can be affected in many ways. Certain types of inclusions, such as clouds and twinning lines, structural phenomena such as graining, and even fluorescence can have an impact on a stone’s ability to transmit light.
The technical qualities (Carat/Cut/Colour/Clarity) can only be considered on an individual basis to the stone you’re looking at. This only further reinforces why it’s so important to consider many options in the technical criteria you’ve fine-tuned so that you can select the best visual option with the highest ‘Raw Crystal Transparency’ for your piece of handcrafted jewellery.
“As your personal diamond broker in Sydney, we look at hundreds of wholesale diamonds every day. If there’s one very important lesson we’ve all learnt, it’s that Technical Quality & Rarity DOES NOT EQUAL Visual Beauty. In fact, technically rare material is more often than not cut to retain weight.???
