How much should the gemstone’s origin matter?

Originally posted on SCMP edited from words by Lynnette Lee

Imagine two big beautiful sapphires, alike in colour, clarity and size, but one has a note that says it comes from Madagascar – the other from Kashmir.

The difference in origin could end up costing as much as US$80,000 per carat. The branding of gems based on the country they were found – commands a premium that translates into thousands of dollars, and buyers are willing to fork out more for stones with labels such as Kashmir, Colombian or Burmese.
The attention to origin is due in part to the way the gems are named – not just an emerald ring, but a Columbian emerald ring – and increased buyer sophistication.
Buyers aren’t just looking at the 4Cs of cut, clarity, colour and carat, but noticing that the most desirable gems in the marketplace don’t just seem to score highly on all these fronts, they also usually come from certain locations. Those names have become synonymous with quality, history and prestige.
Sapphires from Indian-administered Kashmir are the most highly prized for their perfect velvety blue hue. Among emeralds, those of the purest green are traditionally found in Colombia and display a transparency like honey, known as the gota de aceite (drop of oil) effect.
In the world of rubies, Burmese rubies from the region of Mogok are bestowed the name pigeon’s blood, and are considered the gold standard.

People like to know where what they are buying comes from says Helen Molesworth
“The main relationship between origin and value today is one of rarity and history: those origins which famously provided fabulous quality gemstones historically and which today we know are rarely if not producing at all have a premium on desirability,” says Helen Molesworth, managing director of Gübelin Academy.

The Kashmir and Mogok mines are largely depleted and production has slowed to a trickle, while Colombian emerald production is plagued by chronic underinvestment.

But the rarity of the gems seems to fuel demand. So just how much more desirable are these rare gems?

Auction records in recent years show that Kashmir sapphires have sold for an average of US$217,000 per carat, compared to Ceylon and Burmese ones which sold for an average of US$49,000 per carat.

Top quality Colombian emeralds can command US$200,000 per carat, while Zambian emeralds of similar quality have gone for US$50,000.
In 2015, the Sunrise Ruby, featuring a Burmese ruby, set a new record for coloured gemstones when it sold for US$1.27 million per carat, making rubies the second-most expensive gems after diamonds.

In contrast, a pair of ruby earrings from Mozambique sold for just US$222,481 per carat at Tiancheng Hong Kong in December 2017.

Tanzanite, which only comes from one place in the world, is emerging as a potential rival and drawing heavy interest from the Chinese market.
Touted as “the gemstone of a generation”, the gem is celebrating its 50th anniversary since its commercial launch at Tiffany & Co, and supply is expected to run out in 25 to 30 years.
Yet, its prices are much lower than those of sapphires, the nearest blue gem, ranging from the upper hundreds to lower thousands per carat.


Paraiba tourmalines are another coloured gem with a premium on pedigree.

Paraiba tourmalines from the original location in Brazil are the most saturated in colour and hence the most valuable, though similar tourmalines are also produced in Mozambique and Nigeria. However, Paraibas from Brazil are notoriously small in size and difficult to mine, with only one produced for every 10,000 diamonds. Prices often go beyond US$10,000 per carat.

The current fascination with origin is fueled by transparency or traceability led by the emphasis on sustainable and conflict-free sources.

“People like to know where what they are buying comes from,” Molesworth says.

The value attached to labels like Kashmir and pigeon’s blood is so strong that sometimes the significance of their origin is obscured.

 

Origin only becomes a significant factor after the 4Cs
If a ruby from Myanmar was a shade too dark or heavily included, it would still be considered an inferior stone to a vivid red Mozambique one.
The country of origin only adds a premium to high quality stones, but the premium is so exorbitant that it often prices out all but the richest buyers. Ignoring the Mozambique ruby could mean missing out on a chance to own a good stone at a good price.

In the end it’s the beauty that matters…

A beautiful gem is a beautiful gem, no matter where it’s formed. You cannot simply buy a coloured gem off a report based on where it came from – as any origin can effectively produce any level of quality…
