Consider jewelry featuring autumn-inspired gemstones such as late fall sun colored citrine, a smoky quartz, rich amber, gorgeous garnet, or even many shades of topaz, spinel, or tourmaline. These gemstones can infuse a touch of nature’s beauty into your jewelry collection, enhancing your sweater weather look with autumnal tones. Dark jewel tones are also a great choice, purples, wine, deep greens; these can create a beautiful fall look. I, for one, would wear dark purple all year long.
