Gold Sheen Sapphire Price Update 2nd Half 2017

This is the price update for Gold Sheen Sapphire for the 2nd half of 2017. It covers the reported sale prices from the September Hong Kong and Bangkok Gem and Jewelry Trade Fairs.

I have made the following changes to the chart layout:

  • Removed ‘Sell’ and ‘Buy’ prices 
  • ‘Street’ is now ‘Trade Price’
  • Reporting periods are now half yearly, not quarterly. 
  • Added ‘5 Point Moving Average’ price

Since price data comes principally from major trade fairs, ‘Trade Price’ of pieces sold is a more reliable indicator of current price. There are enough data points now to give a meaningful moving average, this should provide a good trend indicator for the future price.

After careful selection of the rough, about 10% of material is suitable for this high grade faceting. Once faceted, only one or two pieces in 10 make this selection. Most pieces show colour change from metallic copper/gold in incandescent light to blue/green in natural light.

While most pieces come opaque, typical of Gold Sheen Sapphire, about 20% come as translucent with yellow, green/yellow and gold hues.

All are available in all calibrated sizes from 3mm to 10mm, or can be cut to order.

Movement in Gold Sheen Sapphire Price

The first and second quarter of 2017 have seen some interesting movement on the price of gold sheen sapphire.

Gold Sheen Sapphire Carat Price Q2 2017 Update
Gold Sheen Sapphire Carat Price Q2 2017 Update

The price for top grade stones has increased slightly in Q1 and remains stable though Q2. Meanwhile prices for all other grades took a dip in Q1 and remain constant in Q2, with the exception of the street price of grade 2 stones which improved in Q2.

It seems clear that the market is becoming more discerning, reflected in the willingness to pay for best quality material. The trend has been for increasing sales from repeat buyers, which have exceeded reported sales from first time buyers for the first time in Q1, and continuing into Q2. This is further reflected in the price drop of lowest grade material, where buyers have been able to negotiate pricing based on large volume orders.

Special promotions for new cutting and polishing techniques as well as the introduction of new cut types and increased presence at trade shows have all contributed to fluctuations in mid to high grade pricing.

Price Chart Key:

  • Grade 1 – No surface defects, no structural defects, or ‘very rare’
    Grade 2 – Eye clean surface, no structural defects, or ‘rare’
    Grade 3 – Minor surface defects, minor structural defects. or ‘common’
  • Anything less than Grade 3 is not available for sale and either discarded or re-cut.
  • “Buy” is the wholesale price for Grade 3 stones in large quantities over 10,000 carats
  • “Sell” is the price offered for sale from retail or trade fare for single stones or small sales.
  • “Street” is the negotiated price for small quantities of stones of various grades.

 

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.
