This antique bracelet is composed of six shaped rectangular pierced decorated links, conjoined with toroid shaped links.

The rectangular shaped links are each set with a stunning feature Old European round cut diamond, collet set to the centre.

Each link is further embellished with two individually collet set baguette cut diamonds flanking the feature stone, in addition to twenty-two eight cut diamonds completing the Art Deco design.

The circular, toroid shaped links are each ornamented with six round faceted cut blue sapphires.

Lovely selection & excellent service

AC Silver has a stunning selection of antique and vintage items. Both of my brooches arrived right on time as indicated by the tracking. They are even lovelier in person and I look forward to wearing them for decades to come. Andrew and Gemma provided excellent communication and prompt dispatch. I would absolutely recommend working through them.

Excellent customer care.

I had to place the order over the phone as my internet was misbehaving. The lady who I spoke to could not have been more helpful and was particularly careful to get all the details correct. I was then informed about the collection and dispatch of the item purchased, by email. The item arrived as expected and it had been most well packed so that no harm could come to it. It was a delight to purchase this item from C6323, AC Silver, and I could not fault any aspect of their customer care. I was highly delighted with my silver mustard pot and it was much better than the pictures on the web site.
