'Island Mystery' Solid Gold Egg

I remember these 22kt Gold Eggs. In 1983, when I was 20, I had a summer job while I was at college. I worked with George Lukes in London, England. George was regarded as the best hand engraver in Britain. He was the hand engraver of choice for the top Bond Street Jewellers; Garrards, Aspreys, Cartier, Tiffany and Mappin & Webbs.

My task was to transfer the drawings and scribe them onto the gold for all thirteen eggs. I had to be very exact with this as George hand engraved the designs over my guidelines. The eggs were then enameled to create the colorful look that they have now.

I was Falsely Accused of Theft !

There was a funny story that involved me. I left on a train for a weekend visit to see my family in Wales. After I had left, George found out that he was missing one of the gold eggs. A frantic search followed and the conclusion was that I might have run off with it. The Police were called and plans were made to stop the train.

This was before the age of cell phones so there was no way to contact me. Much embarrassment was saved when George found the missing egg. It had rolled behind the safe. I returned there on Monday to hear the story of my near-miss with the law.

Being part of this experience is a wonderful memory for me. I was so lucky to be asked to help to make these beautiful jewels.

THE GIANT. A 22CT GOLD AND TRANSLUCENT ENAMEL CONUNDRUM EGG FOR CADBURY'S designed by Alex Styles, 8cm h, by Garrard & Co Ltd, London 1983, cased, 252g

Exhibited: Goldsmiths' Hall London, Alex Styles Retrospective Exhibition, 1988.

The 1984 Treasure Hunt for which Cadbury's commissioned twelve 22ct gold and enamel eggs from Garrard & Co, each with a declared retail value of �10,000, was launched in January of that year to promote its Easter Egg range.

The promotion saw sales of the Cadbury Creme Egg (cost 14p) increase to a near monopoly market share of 94% as eager treasure hunters pored over the accompanying book by Don Shaw (with illustrations by Nick Price) and attempt to solve the twelve riddles as to the whereabouts of the twelve buried caskets each of which contained a scroll that entitled the finder to one of the golden eggs.

The Conundrum was based on the 1979 book Masquerade, central to which author and illustrator Kit Williams buried a jeweled gold hare. There were unintended consequences of both competitions as gold fevered prospectors armed with trowels roamed private land and historic sites throughout Britain. One Conundrum casket was located in a cemetery on the Isle of Man. Cadbury's decided to call off the competition in the face of complaints, risking the ire of frustrated treasure hunters, with several eggs yet to be won. It is rumored a number were eventually destroyed.

One was offered at auction at Bonham's, 28 November 2012 and the 'secret' thirteenth and heavier egg (326.6g), intended as the prize for a Cadbury retailer, was sold Batemans, Lincolnshire, 1 July 2017 (�17,200 hammer price).

The 'Cuckoo Cuckoo' Cadburys Golden Egg

Auctioned at Duke's Auctioneers, UK, in 2018 for $10,000.


The engraved egg was part of the Creme Egg Mystery Conundrum, a promotional treasure hunt by Cadbury's to find 12 eggs in 1983.

Seller, Clive Pinder from Dorset, found the egg 35 years ago at Cricket St Thomas, Somerset. He said: "It was astonishment that we had succeeded."

Mr. Pinder, from Wareham, said he had spent hours searching for the egg after solving the clues from the book and found it under a farm sign.

He said: "By chance, I saw a sign by the side of the road and this sign incorporated several of the clues in the picture in the book. I dug down about 12 inches and felt something really hard." He unearthed a casket containing a gold egg decorated with a cuckoo.

The eggs were designed and made by Garrard & Co, then the Queen's official jeweler, and were estimated to be worth £10,000 at the time. A "secret" 13th that is larger than the rest sold at auction in Lincolnshire in 2017 for £17,200.
