石英｜Quartz

導言｜Introduction

石英並不是只有一種外觀。

它可以無色透明，也可以呈現紫色、黃色、煙褐色與粉紅色；晶體內部可能保存幻影、金紅石、綠泥石及其他礦物，也可能因不同的生長過程，形成權杖、雙尖、骸骨、自癒與其他結構。

這些外觀雖然不同，主體仍然是由二氧化矽構成的石英。紫水晶、黃水晶與粉晶皆被歸入石英品種，主要成分為 SiO₂，莫氏硬度約為 7。真正使它們產生差異的，是色心、微量元素、包裹體、內部結構與形成歷程。

因此，DIYU 不只依照礦物名稱整理石英，而是從四個方向進入：

色彩與品種，閱讀石英如何產生色彩。

幻影與包裹體，閱讀另一種礦物或過去的生長階段，如何被保存於晶體內部。

生長型態，閱讀石英如何向外延伸、覆蓋、分裂、停止與再次生長。

標本形態，閱讀單一晶體、晶簇、母岩與共生礦物，如何共同形成一件完整標本。

在 DIYU Reading System 中，石英閱讀的不是能量，而是形成。

Quartz does not have only one appearance.

It may be colourless and transparent, or appear purple, yellow, smoky brown, and pink. Its interior may preserve phantoms, rutile, chlorite, and other minerals, while different stages of growth may produce sceptres, double terminations, skeletal forms, self-healed surfaces, and many other structures.

Despite these visual differences, the host mineral remains quartz, composed primarily of silicon dioxide. Amethyst, Citrine, and Rose Quartz are all varieties of quartz with the principal composition SiO₂ and a Mohs hardness of approximately 7. Their differences arise through colour centres, trace elements, inclusions, internal structures, and distinct histories of formation.

DIYU therefore approaches quartz through four directions:

Colour Varieties examine how colour appears within quartz.

Phantoms and Inclusions examine how earlier growth stages and other minerals become preserved inside it.

Growth Forms examine how quartz extends, covers, divides, pauses, and resumes growing.

Specimen Forms examine how individual crystals, clusters, matrix, and associated minerals form a complete specimen.

In the DIYU Reading System, Quartz is not read through energy, but through formation.

石英本身可以接近無色，也可能因微量元素、色心、天然輻射、包裹體或人工處理而呈現不同色彩。

這個分類閱讀的是：

同一種主要礦物結構，如何因不同條件，形成不同的色彩與透明度。

白水晶、紫水晶、黃水晶、煙水晶與粉晶，都從這個入口展開。

Quartz may be nearly colourless or develop different colours through trace elements, colour centres, natural irradiation, inclusions, and treatment.

This category reads how the same principal mineral structure develops different colours and degrees of transparency under different conditions.

石英不是一張等待人類投射意義的空白紙面。

它的色彩、包裹體、晶面、裂隙與集合關係，都來自具體的形成條件。

同一種石英，可以因色彩而被閱讀。

可以因內部保留的另一種礦物而被閱讀。

也可以因生長方式、晶體關係與母岩結構而被閱讀。

分類並不是把石英切割成彼此無關的類別。

一顆綠幽靈可以同時是雙尖晶體，也可以與綠泥石共生，並以晶簇形式留在母岩上。它在不同分類中出現，不代表矛盾，而是同一件標本可以從不同入口被理解。

因此，石英分類樹不是用來決定一件標本「只能是什麼」。

它是讓觀看者知道：

同一件礦物，可以從哪些方向開始閱讀。

Quartz is not a blank surface waiting only for human projection.

Its colour, inclusions, crystal faces, fractures, and specimen relationships arise from real conditions of formation.

The same quartz may be read through colour, through another mineral preserved inside it, through its manner of growth, or through its relationship with matrix and neighbouring crystals.

Classification does not divide quartz into unrelated compartments.

A Green Phantom Quartz may also be double-terminated, associated with chlorite, and preserved as part of a cluster upon matrix. Its presence within several categories is not a contradiction. It shows that one specimen can be understood through several entrances.

The classification tree does not decide what a specimen is allowed to be.

It shows the directions from which reading may begin.
