Majority of polished is under one carat but recent discovery of some larger rough – between 5 and 7 carats – is yielding polished up to 2.5 carats, according to Jerod. About 85 per cent is in typical cornflower blue colours while a small percentage is in lavender or purple shades. “An inherent feature of Yogold sapphires is that colour is evenly distributed and the stones do not require heating to improve colour or clarity,” he explained. This is the only known deposit in Montana where the sapphires are found within igneous dykes and are in the typical rhombohedral form. These are distinct from sapphires produced in other areas in Montana that are alluvial deposits consisting of water-worn pebbles, and colours tend to be more teals, greens, yellows and bi-colours. . Production and promotions Yogold has established a cutting facility in Colombo, Sri Lanka to cut its rough production. The facility is managed by Yogold’s vice president for gemstone cutting Amitha Gamage who explained that production is mainly in precise calibrated sizes cut meticulously to ideal proportions with rigorous quality checks implemented at every phase of the cutting. A feature of the polished is that each facet has a mirror polish. Main production is round brilliants as well as princess cuts and ovals. Sizes of current polished output range from 2mm to 5mm while the number of polished sapphires 1 carat and above is increasing. Average monthly production is between 8,000 and 10,000 pieces, Gamage disclosed. Part of the company’s branding strategy for the future is to take Yogold sapphires to the global market with a range of Yogold sapphire jewellery. Yogold also recently concluded an agreement with Colorado-based film production company Mountain Air Productions LLC to create a reality documentary on the renaissance of the Yogo mine. “The episodes will become an important component of Yogold’s global branding and awareness programme,” said Jerod. 企业家Jay Edington获得了该矿山的开采权。Jay与他的儿 子Jerod和Ryan成立了Yogold USA Corp，专营蓝宝石的开 采、切割和销售。 重返市场 Yogold正在实施三阶段开采计划的第一期，并致力在未 来五年内受控有序地扩张。公司主席Jerod分享道：“目前， 我们集中精力满足美国的需求，特别是蒙大拿州。我们现时 大部分抛光产品都销往该州。” 该矿商最近与南达科他州拉皮德城的Riddle's Jewelry签 订了半独家销售和营销协议。Riddle's自设珠宝制造工厂，并 通过分布在美国九个州的65家商店进行销售。 Jerod表示，大部分抛光宝石的重量为1克拉以下，但 最近发现了一些较大的原石，重量介乎5至7克拉之间，所 生产的抛光宝石重量可达2.5克拉。大约85%的宝石拥有 典型矢车菊蓝色，还有一小部分是淡紫色或紫色。他解释 说：“Yogold蓝宝石的固有特征是颜色分布均匀，并不需要 加热来改善颜色或净度。” 这是蒙大拿州唯一一处已知的蓝宝石矿床，蓝宝石产于 火成岩岩脉内，呈典型的斜方体状。这些蓝宝石与蒙大拿州 其他地区出产的蓝宝石不同，后者是由水磨卵石组成的冲 积矿床，颜色多为深绿蓝色、绿色、黄色和双色。 生产和推广 Yogold在斯里兰卡科伦坡设立了一个切割工厂，用于 切割其生产的原石，并由Yogold副主席负责管理。Amitha Gamage解释说，产品主要是按照理想的比例，用心切割成 精确的尺寸，并在切割的每个阶段实施严格的品质检查，确 保抛光宝石的每个刻面都经过镜面抛光。 该工厂主要生产圆形明亮式切割、公主式切割和椭圆形 切割的抛光蓝宝石，尺寸从2毫米到5毫米不等。他们亦正逐 渐提高1克拉及以上的抛光蓝宝石的产量。Gamage透露，现 时平均每月产量为8,000至10,000颗。 该公司未来的品牌策略旨在将Yogold蓝宝石推向全球 市场，现已推出一系列Yogold蓝宝石珠宝。Yogold最近还与 科罗拉多州的电影制作公司Mountain Air Productions LLC 达成协议，计划制作一部关于Yogo矿山复兴的真人纪录 片。Jerod说：“这些剧集将成为Yogold全球品牌宣传计划的 重要一环。” 一家从矿山到市场业务的新进品牌企业，专营稀有 珍贵资源——未经加热的矢车菊蓝宝石，在环球 业界引起哄动，尤其吸引了美国高端珠宝零售商 和设计师的注目。 Yogold蓝宝石成为珠宝商的新宠儿，不仅因为其颜色和 天然净度的价值因素，还因为它所蕴含的复古情怀。这些蓝 宝石来自一个古老而著名的产地——位于美国蒙大拿州尤 蒂卡附近的约戈峡谷火成岩岩脉，在19世纪美国淘金热时 期被发现。 在19世纪和20世纪初的鼎盛时期，据说该矿生产了数百 万克拉的Yogold蓝宝石。这些宝石通常制成订婚戒指和婚 嫁首饰。蒂芙尼的设计师对这些宝石情有独钟，令它们的人 气不断攀升。 然而，由于当时的运营商Intergem申请破产，矿山开采 于20世纪80年代结束，令蓝宝石爱好者大失所望。过去40多 年来，该矿山一直处于休眠状态。直至2019年，矿业和地质 Blue sapphire rough from Yogo Gulch 来自约戈峡谷的蓝宝石原石
