For HK$76,200；本场官方成交结果表HK060125列Lot52为76,200，明确结果含买家佣金，总额另标HK$及including premium。本轮补齐含佣口径。\n来源瑕疵：这张香港结果表的说明误套British Pounds Sterling及GBP费率门槛，而场次名、日期、HK$总额与拍品页HKD金额互相吻合。因此币种依据采用拍品页HKD，含佣依据采用本场结果表；不采用其GBP门槛，也不从中反算佣金或落槌。仍保留部分核对，等待拍卖行更正或书面澄清该模板。\n美元依据：沿用ECB 2025-04-01闭拍日参考汇率，每EUR1兑USD1.0788及HKD8.3943；每HKD1=USD0.12851578，76,200×0.12851578=USD9,792.90。这是历史参考换算，不是富艺斯原始美元报价或实际结算价。整场闭拍日不冒称Lot52逐笔成交时刻。\n缺少依据：修正为HKD口径的本场结果表，或可引用的富艺斯书面币种/模板澄清；逐笔闭拍时间及当期美元报价如需还原，另向拍卖行索取，维持参考美元无需取得买家结算资料。\n实验室原报告不能补证成交佣金；当前链接的销售条件已滚动为新费率，不用于回填2025年费率。","original_currency":"HKD","original_price":76200,"official_price_usd":null,"estimate_currency":"HKD","fx_rate":0.12851578,"fx_date":"2025-04-01","fx_source_url":"https://data-api.ecb.europa.eu/service/data/EXR/D.USD+HKD+CHF+GBP.EUR.SP00.A?startPeriod=2025-03-25&endPeriod=2025-04-01&format=csvdata"},"price_currency":"USD","price_policy":{"currency":"USD","basis":"historical_fx","fx_conversion_applied":false,"historical_fx_provenance":"historical_fx","buyer_premium":"included","missing_price":null,"note":"历史参考换算；含买家佣金。2025-04-01，每1

瑞士SSEF（Swiss Gemmological Institute）2015年2月4日附录函的描述：\r\n\r\n“这种尺寸和颜色的缅甸天然红宝石极为罕见。它拥有卓越品质，堪称大自然的珍宝。”\r\n\r\n同时，古柏林宝石鉴定所（Gübelin Gem

191.58 克拉。俄罗斯克里姆林宫博物馆的钻石宝库中，珍藏有一颗 250 克拉的矢车菊蓝宝石，来自古老的皇室徽章；另一颗则以 叶卡捷琳娜大帝命名，重达 337 克拉。\r\n\r\n在为数极少的350克拉以上的多面蓝宝石中，有一颗极具传奇色彩的宝石长年未被世人所知——亚洲蓝美人（Asian Beauty of Blue）。\r\n\r\n这颗非凡蓝宝石于 1926 年出土于锡兰拉特纳普勒佩尔马杜拉（Sri Lanka, Ratnapura），当地有“宝石之城”之称。1928 年资料记载，该石估价为 50,000 英镑，切割后重量约为 400 克拉，拥有“极佳的清晰度与孔雀蓝色调”。这颗蓝宝石由著名科伦坡宝石商 Macan Markar 所有，该商行创立于1860年，客户包括英国国王 爱德华七世 与 乔治五世。\r\n\r\n1937 年，这颗蓝宝石被英国工业巨头 纳菲尔德勋爵（Lord Nuffield） 收购。他是莫里斯汽车公司的创始人、牛津大学纳菲尔德学院的捐赠者及慈善家。他为何购入这颗宝石不得而知，传言称原计划作为礼物赠予 伊丽莎白王太后，并与1937年5月12日的加冕日有关。然而，这颗宝石在之后的35年间失去踪迹。\r\n\r\n直到1970年代，瑞士著名宝石商 西奥多·霍洛维茨（Theodore Horovitz） 才有机会检验这颗蓝宝石，并留下了关于其重量与切工形状的重要记录与图纸。\r\n\r\n如今，这颗沉寂多年的“亚洲蓝美人”终于重回世人视野。其卓越的体量、罕见的孔雀蓝色调与非凡净度使其跻身世界级蓝宝石之列，无疑是收藏家梦寐以求的终极宝石。","url":"/ins-86","photo_url":["https://www.zxnb.com/uploads/gemstones/1754669348_6702b785b7832c007783.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_d967003855f9cf9099f2.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_3247283a5a095515ccba.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_df59a6a3c7f93ed08c5b.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_34766a3621c9f1772f22.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_63f76deb32165545e814.jpg","https://www.zxnb.com/uploads/gemstones/1754669348_9cb18b4fd30c0a2e6ec8.jpg"],"start_price_usd":null,"status":"ongoing","treatment":"无处理","certificate_type":"[\"SSEF\",\"AGL\",\"G\\u00fcbelin\"]","origin":"斯里兰卡","color_grade":null,"auction_start_time":null,"auction_end_time":null,"bidding_count":"0","is_featured":"0","created_at":"2024-11-15
