Onyx windlight (L). Onyx windlights bring a unique, warm atmosphere to any interior. Onyx is a semi-precious stone known for its beautiful translucent structure and natural hues, from soft cream and honey yellow to deep green or amber. When a candle burns in it, the light subtly illuminates the veins and patterns of the stone, creating an enchanting and soothing effect. Each windlight is handmade and unique in shape and pattern, making it not only a source of soft light, but also a stylish piece of nature in the home.
