{"type":"firestarter.listing","listing":{"id":"lst_UjuLkN25","product_name":"Gemstone Heart Ring","category":"Rings","description":"This chic solid gold piece makes an adorable promise or engagement ring for your partner. When designing this ring, our founder AL wanted to create a symbol of two halves joining to make a whole. In the center of a recycled solid gold or platinum band, two separate pear-shaped stones form one beautiful heart. The gemstones on this engagement ring are set low to the finger, so it’s super comfy to wear. A durable, adorable, and unique ring to give to the one you love or to show your self-love by wearing it as an everyday ring.\nRing comes with an Automic Gold ring box.\nWe can customize this ring with any design and any natural or lab-created stone. Contact us for a custom piece.\nNeed help deciding between Platinum and White Gold?
