Rare Gemstones For Sale

Rare gemstones for sale at auction is a story that appears in gemstone and jewelry industry news media several times each year.

Usually the article refers to a high-profile auction by an equally high profile international auction house. The actual seller may be a celebrity, or possibly have a royal title. These auctions attract a lot of attention... because of the current owner or the history of the items, as well as the quality of the gems featured.

Rare gemstones for sale at auction attract potential buyers from around the globe to be at these sales in person. In short... each of these auctions is an "event" in the gemstone and jewelry world.

Rare gemstones for sale at auction have been fetching record sale prices over the past year or two.

Now comes word of a different type of auction. The auction house is not so high profile, and there will be no assembly of high profile buyers. This sale will be held on the internet, and it will occur in segments.

The colored gems are touted as being some of the very best nature has produced.

Most of these colored stones are mounted in jewelry pieces with an abundance of diamond accents. The images of the jewelry mountings show that the mountings are lavish in their own right.

There are more unusual aspects to this sale than the fact it is being held online where anyone can register their interest in participating in the auction....

The auction house is John Pye Auctions. This house may be known in Britain, but it is not thought of as competition for Sotheby's, Christies, Doyle New York, and Bonhams... yet.

Another unusual aspect is that the seller is referred to as "the anonymous owner" while the gems and jewelry are named "the David Jerome Collection".

The news release announcing the auction states:


UK’s Most Valuable Private Gemstone Collection Comes to Auction

One of Europe’s largest private collections of precious coloured natural gemstones is to be sold in a multi-million pound international online auction offering.

Some of the world’s rarest and purest rubies, emeralds, tanzanites, sapphires and other prized gems forming over 680 gemstones from the esteemed David Jerome Collection are to be presented to the international market by John Pye’s Luxury Assets Division, a division of John Pye Auctions.

The rate of rising values of coloured gemstones are now outstripping those of diamonds as royals and celebrities alike, including the Duchess of Cambridge, highlight their appeal and have raised their highly prized profile, establishing 2015 as ‘The Year of the Coloured Gemstone’.

Ethically sourced directly from precious gemstone mines all over the World – including but not limited to Burma, Sri Lanka, Tanzania and Zambia – only the finest natural stones have been selected for the collection, valued at over £8 million retail.

All precious gemstones within the collection were originally sourced as loose gems. It is only in recent years these gems have been set and mounted amongst diamonds, into pieces of fine jewellery, to showcase their desirability and make them a suitable offering for the international public auction market.

The anonymous owner has collected the gemstones for over 40 years after buying a highly-prized 133 carat Tanzanite – which ignited a passion to source a range of gemstones from all over the world.

Through decades of global travel, the private client has become established and recognised by gemstone miners as one of Europe’s preeminent buyers of natural coloured gemstones. The collection includes a matching set of 35 carat Zambian emerald earrings with an estimated value of £500,000 to £600,000.

John Pye gemstone Valuer Ian Hall said: “This is quite simply a once in a lifetime opportunity to buy from an exquisite and extremely valuable collection of gemstones. We believe the collection to be certainly the largest in the UK, if not Europe.

Every gemstone in the collection has its own independently-issued certificate, a guarantee of both authenticity and quality, including Gem Research Swisslab (GRS) Certificates showing that they are the purest quality in their natural form.”

Coloured gemstones have been rapidly growing in popularity and these rising asset values are being reflected in auction rooms globally, with a World record realisation set this Spring for a ruby sold at auction in Geneva for £19.4m.

John Pye Director Sheldon Miller said: “Not only are the pieces up for auction truly unique, but they also offer significant investment potential.

Auction rooms across the globe are seeing record-breaking sales. We are expecting substantial interest from international buyers. It is extremely rare a collection of this purity and size comes to the market.

It has been a labour of love for our client, who has sourced only the best and clearest stones directly from mines around the world.”

John Pye’s private client, who wishes to remain anonymous, said he wasn’t sorry to see the collection broken up because he wants others to enjoy them.

I am an avid collector and I love sparkly things,” he said.

I started my collection with a tanzanite. I began to search for the best available stones and I learned all about them. My knowledge of gemstones has grown over the years and I can tell the difference between a stone that has been heated or tampered with.

I love the buying, the finding of the mine and acquiring the very best stones. The best mines from all over the world come directly to me with their finest stones. We are giving people the opportunity to buy the most beautiful stones in the world, just as nature created them.

I am now happy for the stones to be sold so other people can enjoy them as much as I have.

The owner has travelled all over the world – including Burma, Sri Lanka, Tanzania and Zambia– to source the stones which he says are of “Bond Street quality”.

Sheldon added: “Our client has set conservative reserves based somewhat marginally above mining sourcing prices, yet considerably below retail values.

This presents auction buyers with a unique opportunity to acquire the finest natural grade gems at investment value.

John Pye Auctions shall present the collection to market through a series of online auctions later in the year, we are now taking registration of interest online for prospective bidders requiring further auction updates and catalogues as and when they are made available.

The collection of precious gemstone jewellery ranges in value from an 8.96 carat pink Topaz ring with a £600 estimate, to an extremely rare matching set of Zambian emerald earrings totalling 35 carats estimated to be valued at over £500,000.

The first auction in September will offer 345 coloured stones.

Earlier I said John Pye Auctions is not thought of as competition for the high profile auction houses. Another news release from the company makes an announcement captioned John Pye Launches Luxury Assets Division.


Rare gemstones for sale direct at the mine, from a respected dealer, or through a respected auction allows those with the means to acquire an example of nature's best. As for the rest of us, it is fun to read about.
