This exciting Celtic knot bracelet is style # 339 of my online selection catalog. The head is hinged on one side and has a C catch on the other so it is easy to put on. The gemstone is secured by a full bezel mounting centered in the knot created by ajoure work. Ajoure is the art of cutting away to create an image rather than filigree which is generally wire that has been added and soldered into an opening. Ajoure art stays brighter and is stronger as there is no solder involved thus creating a better heirloom. Though filigree is more famous and much faster to create, I prefer the quality of ajoure. The band of this unique bracelet is made from hand pulled tubing for a larger show of silver. The balls that flank the head are also hollow to keep the weight comfortable while the appearance is enhanced. A sturdy and stylish design that is easy to wear. The gem is a lovely natural light medium purple Amethyst faceted oval measuring 12.5 x 10 mm and weighing 4.25 carats. This is a naturally mined gem from Asia that has had no treatment. The clarity is VS eye clean and the cut is good thus there is a nice sparkle. Amethyst is the birthstone for February. This sweet bracelet measures about 7 inches with a 57mm diameter and weighs about 31 grams.
