This sweet little green triangle of seaglass, found on Happisburgh beach in Norfolk, England, has been set in fine silver, on a sterling silver closed bangle. 
 
Size: M (medium)
 
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).
 
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; and the date mark ('V' denoting the year 2020, or 'W' for 2021).
 
 
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.
