The Diamonds Of Da Vinci Diamonds
It's strange that the slot Da Vinci Diamonds has the word 'diamonds' in the title at all. All the stones featured in the game are certainly precious gems, but none of them has the supreme durability of the hardest substance known to man, because none of them are diamonds! Imagine the pressure that would need to be applied to diamonds to get them to explode to create the tumbling reels feature this slot is so well known for. While we're on the subject did you know that a diamond is the only stone that can take the pressure of twenty five facets across its cut face? There's a method that's used to rate the hardness of a gemstone called the Mohs scale. It was created way back in 1812 by German geologist Friedrich Mohs and it's based on the ability of a material to scratch another, in a kind of ‘battle of the minerals'. Diamonds rate a whopping 10 (there is no eleven here, apologies to the Spinal Tap fans) at the top of the scale as the yardstick by which all other substances are compared to and are quite literally the ‘hardest' mineral in the entire geological playground.
When you look at all the facts, it's no surprise the developers of Da Vinci Diamonds actually chose some more breakable gems for the reels of this awesome slot game. So let's take a look at how strong the stones featured in the game actually are.
Emeralds are found all over the world, especially on the continental land masses of Asia, Africa and America. They vary in colour from an almost yellowish hue, through various colours of green (blue yellow mix) to a deep green-blue, and this colour in the stone is caused by chromium and vanadium. For some reason it's considered acceptable to oil these stones to improve the lustre and colour before sales, although the practice of using green tinted oil is banned. So how hard are these little green pebbles? Well these guys are pretty tough rating around 7.5 – 8 on the good old Mohs scale of hardness.
Rubies are precious red gems that are almost as hard as diamonds. They're valued on the clarity of colour through-out the stone and the redder the stone, the better the price to be expected at market. They can be treated with heat to improve the quality of the stone and in the 1990s the market was flooded with heat treated rubies that were often cracked or flawed in colour. Unlike many other gemstones and crystals, rubies do not appear all over the world, with Burma packing the biggest concentrations. On the Mohs scale they rate a whopping 9.0 making them a serious contender in the durability stakes.
Sapphires are incredibly beautiful blue stones that are associated with the Far East and parts of Africa. They can now be ‘grown' in a laboratory thanks to a process created over a hundred years ago by a Frenchman called Auguste Verneuil, which has bought the price of down considerably from what it once was. Sapphires are incredibly similar in structure to rubies and have are given a different colour due to the different chemical state of the chromium that's apparent in the molecular structure of both stones. It's no surprise then really that these little pieces of beautiful crystal also rate at a whopping 9.0 on the Mohs scale.
Pearls are the odd one out in the Da Vinci Diamonds as they are not made in the same way as the other igneous, pressured stone creations that feature in the game. Pearls are created in the mouths of clams and oysters and are simply calcium carbonate layers that have built up over time. They are incredibly soft when compared to most other precious gems with a Mohs scale index of 2.4 -4.5, so it's no wonder Cleopatra could eat one of these little white balls dissolved in a glass of vinegar.
