Gold Sheen Sapphire and Ruby in Mens Jewelry

Gold sheen sapphire and dark, vivid ruby is ideal for men’s jewelry.

Typical design styles for men’s jewelry use flat mountings with large(er) size gemstones.  This requires a faceted gem with a larger table size, or flatter cabochon that presents well, which favors opaque over transparent stones.

For example, this gold sheen sapphire ring has a 45ct stone with a 22mm x 16mm table. The faceting picks up brass, copper and gold tones as light plays across the surface.

The rubies in these rings are cabbed from the same piece of rough ruby. In larger sizes, the dark tone with strong saturation is great for men’s rings, yet still beautifully feminine in smaller sizes.

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.

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.

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:

Gold Sheen Sapphire Pendant
29 carat gold sheen sapphire. What better to enhance the beauty of the décolletage than a Gold Sheen Sapphire pendant?

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.

New Factory Cuttings – Gold Sheen Sapphire

The latest batch of Gold Sheen Sapphires from the factory are showing some remarkable characteristics.

First, we are seeing vivid asterism in the cabs.  All gold sheen sapphires cabs have some degree of asterism, but usually it is quite faint.  The rough we are cutting now seems to have more rutile, which gives them both a ‘sleepier’ look, and the much more prominent star:

You can see the rutile silk under multiple light sources (with a single light source, these would have a prominent star)

Then, there was this incredible find – for the first time we have seen completely transparent gold sheen sapphire with full sheen and star effect.  The smartphone snapshot does it no justice, but imagine the transparency of a vivid blue medium tone sapphire, but instead of blue, the colour is golden sheen.

Out of 200,000 carats cut, we have found less than 20 carats of stones like this. We know how to cut is as cabochons, so that is what the factory did.  But what I am thinking is, what if we faceted it with a brilliant cut?  I’ll run it by Tanzim and see what he thinks.
