認識寶石

寶石的生成

寶石的生成需要數百萬年以上,並且配合適當的環境與地質等條件。因此寶石是非常珍貴與難得的,可以說是上帝的禮物。一般來說,被稱之為天然寶石的,代表該寶石是從自然的大地中生成的,而非從人工實驗是產出。而因為是天然生成,即便為同一種寶石,每顆寶石的顏色都不盡相同。天然寶石也都有可能有些微內含物或天然紋路存在,這樣的內含物除了代表這顆寶石特別的生成經歷以外,更是天然的證明。

寶石的定義

寶石的定義需具備以下三個條件:美觀性,稀有性,堅固性。寶石的第一條件必須是美麗,要有讓人想擁有與收藏的欲望。寶石的第二條件是稀有,俗話說:物以稀為貴。例如彩色鑽石,即因為產量較白色鑽石稀少,因此成為寶石收藏家爭相收藏的對象。寶石的第三要件,在地球上許多美麗的礦物之所以無法被定義為"寶石",與堅固性、耐用性、穩定性,有相當大的關係。倘若穩定性不高,可能在受光照或是接觸化學元素以後,就失去原先美麗的因素。且自古以來,寶石皆做成珠寶首飾配戴在人的身上,若非耐久,很難經起配戴時的摩擦或碰撞。例如螢石,雖然色彩多變絢麗,但卻因為莫氏硬度僅有4,無法鑲嵌於珠寶首飾。

淺談寶石優化

在古代,僅有皇宮貴族才能擁有美麗的寶石,例如古代楚國發現和氏璧的卞和,為了向君王獻上稀世珍寶和氏璧,不惜被砍斷雙腿。隨著科技與社會文明的進步,美學品味的提升,過去遙不可及的珍貴寶石,不再是貴族、富豪、名人的特權。而為了供應市場的大量需求,加上科技進步的配合,許多提升寶石穩定性、
堅固性的處理方法也就因應而生。除了避免地球上珍貴而有限的寶石資源浪費外,更能讓大眾以親切的價格取得美麗的寶石。

最廣為人知的寶石優化莫過於祖母綠浸泡天然植物油,浸油的祖母綠更顯得光彩美麗,而這樣的處理方式是全世界所認可的。另外,為了使顏色更加的穩定,市場上絕大部分的剛玉皆有經過加熱優化處理。優化的寶石,幾乎能永久的維持該特性,不因時空或環境而改變。 目前市場上絕少存在未經優化處理的寶石,除非是年代十分久遠的古董珠寶之外,或是拍賣會場上特別註明未經加熱處理的珍貴寶石,當然由於未經處理的寶石非常的稀少珍貴,價格自然也十分的高昂,且大部分僅能於拍賣會場裡覓得,一般消費者難以親近。

目前國際寶石界對於寶石的優化處理採認可態度,也因行之有年而廣泛被消費者接受,但做生意貴在誠信,因此寶石界一致主張在銷售之前需明白的告訴消費者。除此之外,珠寶業者也須負擔起教育消費者的責任,畢竟在這個寶石資源日漸開採殆盡的時代,兼具環保,美麗、安全、經濟的寶石,才是消費者最好的選擇。
