我们的起源
黄金与白银
我们加工的每一克金属，都在地球诞生之前很久，于恒星内部及其碰撞中形成。这是它们的旅程。
黄金
原始形态：石英中的自然金
- 诞生 黄金无法在恒星的普通核聚变中形成。在两颗中子星的碰撞（千新星）以及某些巨型超新星中，原子核在几秒钟内俘获中子，从而变成黄金。据估算，2017年观测到的一次碰撞就产生了相当于数个地球质量的黄金。
- 旅程 这些恒星残骸散布于太空，与气体和尘埃云混合。约46亿年前，太阳系正是从这样一片已富含黄金的云中诞生。
- 抵达地球 当年轻的地球仍处于熔融状态时，大部分黄金沉入了地核。人们认为，今天开采的黄金是约40亿年前随小行星大轰炸来到地球的。
白银
原始形态：矿脉中的丝状银
- 诞生 白银形成于质量约为太阳8–9倍的恒星的超新星爆发，通过“弱r过程”产生；还有一部分在衰老的红巨星中通过慢中子俘获（s过程）形成。
- 旅程 由于这类恒星比锻造黄金的碰撞更为常见，白银的丰度远高于黄金。它也汇入了同一片云，成为太阳系的原始物质。
- 抵达地球 白银成为地壳的一部分，在热液矿脉中富集，有时会结晶成如图所示的细丝。它在地壳中的平均含量极低（百万分之0.08），但仍是黄金的许多倍。
在我们的工坊里，我们将这两种金属加工为9K–18K黄金和925银。

宝石背后的故事
宝石指南
了解宝石如何形成、如何被发现，又如何穿越历史走进现代珠宝。
始于1461年 · 伊斯坦布尔大巴扎
传承五个世纪的工艺，今日的工坊。
自15世纪起，伊斯坦布尔大巴扎便是世界最重要的珠宝中心之一。师徒相传的技艺，至今仍以同样的耐心贯穿铸造、锉修、镶石与抛光的每一道工序。
每件 OSKA 作品都始于纸上：先是铅笔草图，再进行尺寸与细节推敲。我们的 Panther 手镯正是这样诞生的，男女皆宜：蜂巢纹镯身、逐颗手工镶嵌的豹首，以及牢固的扣合设计。
OSKA 源自这一传统。在我们的工坊里，传统手工艺与现代 CAD 技术相结合，为您的品牌带来稳定、可复制的品质。
