J.K. Rowling's thoughts
I did not invent the concept of the Philosopher's Stone, which is a legendary substance that was once believed to be real, and the true goal of alchemy.
The properties of 'my' Philosopher's Stone conform to most of the attributes the ancients ascribed to it. The Stone was believed to turn base metals into gold, and also to produce the Elixir of Life, which could make you immortal. 'Genuine' alchemists - the forerunners of chemists and physicists - such as Sir Isaac Newton and (the real) Nicolas Flamel, sought, sometimes over lifetimes, to discover the secret of its creation.
The Stone is variously described as red and white in the many old texts in which it appears. These colours are important in most accounts of alchemy, and are often interpreted as having symbolic meaning.

From the story
The Philosopher’s Stone can turn metal to gold and produce the Elixir of Life, which makes the drinker immortal. The only known Stone in existence during Harry’s first year belongs to Nicolas Flamel. Voldemort spends most of Harry’s first year trying to get the Stone: he forces Professor Quirrell to try to steal it from Gringotts, and, on failing, attempts to steal it from Hogwarts. Harry, however, obtains the Stone first and refuses to hand it over, even when Professor Quirrell attacks him. After Voldemort flees the school, Professor Dumbledore arranges for the Stone to be destroyed.

300天的寻求 600年的守候
—— 财富•永生
——魔法石
J.K.罗琳认为：
我并没有发明魔法石的概念——一种传说中的、曾经被认为是真实的、真正目标是炼金术的物质。
“我的”魔法石的属性符合大多数古人归于它的属性。石头被认为能将贱金属变成黄金，也能生产出能使你永生的长生不老药。“真正的”炼金术士—化学家和物理学家的先驱者—例如艾萨克·牛顿和（真正的）尼可·勒梅，在有生之年探求过其蕴涵的秘密。
在许多提到过它的旧文献中，这种石头被不同地形容为红色和白色的。这些颜色对于大多数炼金术来说是最重要的，并往往具有象征含义。
在这个故事中：
魔法石能将贱金属变成黄金，也能生产出能使饮用人永生的长生不老药。在哈利（上霍格沃茨）的第一年，唯一已知的魔法石属于尼可•勒梅。
伏地魔在哈利（上霍格沃茨）第一年的大部分时间里努力得到魔法石：他命令奇洛教授从古灵阁偷取它，失败了。（然后）试图从霍格沃茨偷取它。然而哈利首先得到了魔法石，甚至当奇洛教授攻击他时也拒绝交出。然后伏地魔逃离了学校，邓布利多教授安排将魔法石摧毁。

我很好奇黑魔王得了魔法石之后又能如何？
