Charles Lawson has just posted his latest video featuring Gold Sheen Sapphire on his YouTube channel.
This is an informative video on the cutting and production process. I even have a small speaking part.
David Yurman Feature Gold Sheen Sapphire in 2017 Lunar New Year Collection
Top ranked jewelry designer David Yurman today released their 2017 Lunar New Year Collection featuring Gold Sheen Sapphire.
“The Men’s DY Fortune collection includes designs crafted with octagonal cut stones – a reference to the lucky number 8. Evoke good karma with these extraordinary pieces.”
– David Yurman announcement newsletter
As for the octagonal cut, the raised facets presented quite a challenge for the cutting factory. Making that design in garnet is one thing, but quite a lot harder when cutting sapphire. Nevertheless, the skilled artisans rose to the challenge and filled the order ahead of time while achieving a remarkable consistency of 0.1mm tolerance.
I am very proud to have been able to meet the high quality demanded by David Yurman – which required a concerted team effort over three months. It simply would not have been possible without the dedication of Tanzim Khan and his exceptional team.
The designs on the DY website are:
DY Fortune Faceted Amulet with Golden Sheen Sapphire in 18K Gold
DY Fortune Woven Station Bracelet with Golden Sheen Sapphire and 18K Gold, 11mm

Wikipedia Article for Gold Sheen Sapphire
I have just completed the draft of a wikipedia article for gold sheen sapphire. You can see the draft here – https://en.wikipedia.org/wiki/Draft:Golden_sheen_sapphire.
It’s been a long time since I tried to edit anything in Wikipedia, and it still remains a fairly esoteric publishing system. But I have to say that the visual editor and upload wizards do make things quote a bit easier.
Here is one of the photos from the article:
Now just to wait while the Higher Powers of Wiki review the draft. Hopefully it will not need too many revisions to get accepted in the article space. I might just go sacrifice a chicken to appease the Wiki gods, just in case.
Gold Sheen Sapphire Article and Lab Report from GIT
The GIT (The Gem and Jewelry Institute of Thailand) has just completed an excellent lab report on gold sheen sapphire. They have also featured gold sheen sapphire in the latest GIT magazine.
From the lab report:
Golden Sheen and Non-Sheen Sapphires from Kenya

Abstract
A new variety of sapphire from Kenya with unique golden sheen ± star phenomena, the so- called
“Gold Sheen” sapphire has been introduced to the gem market in the last 6-7 years. This study was aimed
at characterizing both the sheen sapphire and non-sheen sapphire from the same locality. It was found that
both sheen and non-sheen samples shared somewhat similar inclusion assemblages, namely magnetite,
goethite, hematite, short needles and zircon. The sheen stones, however, were apparently translucent to
opaque with golden sheen ± star effect caused by the reflection of the light from the combination of dense
and well-oriented reddish brown platelets and short needle-like inclusions exsolved along three
crystallographic directions in the basal pinacoid of sapphire. The transparent-to-semi-transparent nonsheen
stones, in contrast, contained relatively much less amounts of platelets and needles. The advanced
analyses revealed that both sheen and non-sheen sapphires contained high iron content, including boehmite,
diaspore and kaolinite which were good indications of untreated stones.

Gold Sheen Sapphire in Jewelry
I had a number of pieces of my gold sheen sapphire collection made into jewelry. This was partly on the recommendation of a friend, and partly for my own curiosity.
I am not by any means a jewelry designer, so i just gave some basic instructions to the goldsmith and let him come up with the settings he thought best. I didn’t want to spend a lot on the manufacture, so I used silver with either yellow gold or rhodium plate. The results turned out better than I expected:
Then, while sorting through my collection, I pulled out some of the larger cabs, and started to idly arrange them into a necklace pattern. Hmm, I thought, that would make a pretty nice necklace. And so I ended up with this stunningly gorgeous necklace with over 300 carats of star gold sheen sapphire.
Beautiful, isn’t it? But even more beautiful on a beautiful neckline:
Gold Sheen Sapphire Price Update
The price of gold sheen sapphire continues to rise. This is the origional post of the two year price history – http://sjwgems.com/articles/price-of-gold-sheen-sapphire-2-year-history/. Now here is the price update:
I am not particularly surprised that the price of the highest grade cut is so strong. The latest batch I reported here http://sjwgems.com/articles/new-factory-cuttings-gold-sheen-sapphire/ really are spectacular.
I heard a comment today from a long time collector and now investor in gold sheen sapphire. He said “The more I handle and look at the goldsheen (sic) sapphires, the more I appreciate their unique beauty”. Which is my own sentiment exactly, and I think that is also evident in the strengthening market price.
金光藍寶石(Gold Sheen Sapphire)之美
我一直在嘗試着怎樣用相機捕捉金光藍寶石(Gold Sheen Sapphire)的美，我試過用高參數的數碼單反相機轉換不同的光線和參數設置，但還是不能拍出理想的照片，甚至有時用手機拍看起來更好。
金光藍寶石的發現人Tanzim Khan 先生形容這種複雜的各式各樣的圖案就仿佛帶着你去旅行。不是嗎？當你全神貫注地凝視它的時候，你會看見更豐富的圖案和美結合在一起向寶石內部延伸，那種3D效果其它寶石是無法展現的。
跟紅寶石一樣，金光藍寶石在暖光或早/晚時的自然光下觀看最為亮麗。在直射光和冷光下，一些色彩可能被遮掩，但在較強的白光照射下會呈現出明快的藍色，看起來像是藍寶石被鑲嵌在青銅的籠子裡。
金光藍寶石(Gold Sheen Sapphire) 的價格走勢
自從2014年第一次收藏金光藍寶石 (Gold Sheen Sapphire) 開始，我就一直在跟蹤記錄它的價格走勢。最近，市場價格（街價)節節升高，應是因為已逐步得到珠寶設計師和投資者的關注。
由最初金光藍寶石的發現人Tanzim Khan 先生不遺餘力地介紹和向我傳授這一新剛玉品種的知識到漸漸熟知它的特質，結構和屬性，我在網站上發佈了金光藍寶石的簡介。同時，我也與Tanzim 先生及一些有興趣參與的寶石實驗室一起研究及制定金光藍寶石的分級別系統。
以下是金光藍寶石2年來的價格走勢：
圖表說明:
目前我們採用三級制來劃分金光藍寶石
一級 ﹣ 表面及結構上無瑕疵， 或者極微小瑕疵
二級 ﹣ 肉眼看不見表面瑕疵，結構上無瑕疵或很少瑕疵
三級 ﹣ 表面及結構有微小瑕疵，或普通瑕疵
任何低於第三級標準的，則不適合出售或應重新切割。
圖中”Buy” 即”買“是屬第三級別金光藍寶石的批發價，通常訂購數量超過10,000 克拉。
圖中”Sell” 即”賣“ 是珠寶商或貿易展覽的零售價格，通常是單一或很少量貨品。
圖中”Street” 即”街“ 是少量訂購且混合不同級別的協議價格。
金光藍寶石亦有特別的出售價格，通常是超過50克拉的一枚石頭供收藏用途。這類的價格範圍很廣，可以是每克拉100美金甚至無價，最終價格取決與買賣雙方議價的幅度。我的網站上展示了一些標有規格重量的金光藍寶石的樣品和批發價格，有興趣可點擊查看 website.
由以上圖表可看出，目前金光藍寶石的批發價仍然遠遠低於街價，這對珠寶零售商和珠寶設計師們來說，應該是個好消息吧。
