2022 marked two major events in the history of Britain's monarchy: the celebration of the Silver Jubilee marking 70 years of the reign of Queen Elizabeth II, and then, sadly, her passing later that year. 
 
She was the first British monarch to celebrate a Platinum Jubilee, having acceded to the throne in 1952. To celebrate the occasion, the British Hallmarking Council sanctioned a unique commemorative component mark. Designed by Thomas Fattorini, this unique, special mark depicts the initials 'QEII' and the number 70, encased within an orb.
 
To mark the occasion of the Platinum Jubilee, I created a limited number of commemorative open-cuff sterling silver bangles specifically to feature this special stamp in a large, decorative size alongside my regular hallmark. 
 
The UK assay offices ceased applying the Platinum Jubilee stamp at the end of 2022.
 
Size: L (large)
 
What size will fit me?
 
To find the best fit, you first need to measure your hand, rather than your wrist!
 
You'll need a measuring tape, or piece of string.
Bend your thumb as far as possible into your palm as if you are trying to get the tip of your thumb to touch the tips of all four of your fingers at once (i.e. the kind of position you'd put your hand in to put on a bangle). 
Wrap the measuring tape or string around the widest part of your hand (over the knuckles and thumb), keeping it tight rather than loose as you are looking for the smallest you can make your hand.
Make a note of your size, or mark the string where it meets and measure against a ruler.  
 
In centimeters, the readings (give or take a couple of mm either side) would correlate to the following bangle sizes:
 
21cm = small
22cm = medium
23cm = large
 
If you have an existing bangle, simply measure the inner diameter by placing it on a ruler or tape measure, and measure straight across the middle. The sizes are 60mm for small, 65mm for medium and 70mm for large (allowing for a margin of error of a couple of mm either side).
 
Open cuff-style bangles allow more leeway as they slide directly onto the wrist via the gap, and do not need to pass over your hand. Measurements for these would be 55mm for small, 60mm for medium and 65mm for large (again, allowing for a margin of error of a couple of mm either side).
 
 
Fully hallmarked by the Edinburgh Assay Office. 
 
A hallmark tells the story of who made an article, what the article is made of (gold, silver, platinum, or palladium), the fineness of the precious metal, and where the article was assayed.
A hallmark must consist of at least three compulsory marks: a sponsor’s mark (maker’s mark), a metal fineness mark, and an assay office town mark.
A hallmark may also include an optional date letter, indicating when the article was hallmarked, or an optional traditional metal fineness mark, such as the Lion Rampant (sterling silver). 
The UK Hallmarking Act 1973 states that all silver items with a metal weight of more than 7.78 grams must be hallmarked. 
 
Seadragon Silver's hallmarks include the maker's mark (the initials SM in a quatrefoil); two metal fineness marks (925 and the Lion Rampant) to denote sterling silver; the Edinburgh Assay Office mark (castle); and the date mark ('W' for 2021; 'X' for 2022).
 
 
About Seadragon Silver
I was born in the Year of the Dragon according to the Chinese zodiac, and I love creating beautiful jewellery using seaglass, most of which we find along the beautiful beaches of the North Norfolk coast here in England. Some of it comes from much further afield, thanks to friends who send me 'mermaid mail' from as far away as Japan, Tasmania and the United States.
 
I'm proud of every piece I make, and I hope you enjoy wearing my jewellery as much as I love making it.
