Vintage silver tone handmade amethyst link bracelet

Vintage handmade link bracelet. With natural amethyst stones of light purple/ lilac / lavender color. The closure has three settings, so it fits sizes 7", 7.5" and 8". In very good condition, as pictured. All links are securely soldered. The top part, around the stones, looks like sterling silver, but I can't find any stamps. The bottom base metal is different and looks like possibly silver plated brass.
