Converted from a pair of antique cufflinks, are these beautifully enamelled forget me not hoop charms. They can be purchased with or without a pair of 9 carat gold hoop earrings (as shown in the photos) please just select the option from the listing. 
There is only one pair, but to list with the option to buy with or without hoops I have to put two pairs in stock, so if it is showing as 'partially out of stock' then please do note they have sold.
 
The guilloche enamel is in wonderful antique condition. The technique used to create the pearly white base uses a combination of engine turned engraving and vitreous enamel to give a highly lustrous effect. The forget me not flowers have been hand painted in enamel on top which gives the overall look a great depth. 
 
There are some small nibbles to the edges but they really don't impact when worn.
 
The backs show the anchor mark for the Birmingham assay office, the passant lion for 925 silver and the letter h for 1907. There is a small polished area to the reverse where the cufflink fittings were removed.
 
If you choose to buy the new gold hoops with them, the details are as follows: Width: 1.8mm Height: 11mm Internal diameter: 8mm Weight: 1.05g for the pair, marked '375' for 9ct gold.
