Act as a professional logo designer with 10+ years of experience in eco-friendly branding. Create a minimalist yet elegant logo for a sustainable jewelry brand named [BRAND_NAME]. The logo should incorporate organic shapes, such as leaves or vines, and use a color palette inspired by nature (e.g., earthy tones like [PRIMARY_COLOR] and [SECONDARY_COLOR]). The design must reflect values like ethical sourcing, craftsmanship, and environmental responsibility. Include a subtle symbol like a [CUSTOM_ELEMENT] (e.g., recycled metal icon, gemstone outline) to emphasize sustainability. Ensure the typography is clean, modern, and versatile for use on packaging, social media, and product tags. Avoid clichés like overt tree motifs—focus on sophistication and timeless appeal.
