{"type":"firestarter.listing","listing":{"id":"lst_DmCt7KsR","product_name":"Alexandrite Cluster Ring with Band","category":"Rings","description":"“I love this ring because it’s a classic engagement ring but also the deep color and asymmetric cluster make it very fun and unique. I love the hidden flower detail underneath the main stone and I really love the matching wedding band because it reminds me of nature and a mountain range.” - AL (founder of Automic Gold)\nChange is good, especially when you have a color-changing engagement ring. This gorgeous ring features clusters of green-blue alexandrites and clear moissanites framing a stunning lab alexandrite center stone that changes its hue from purplish-green to bright red in direct sunlight. The eight-prong setting keeps the center stone secure and adds a cute hidden petal design under the stone. This solid 14k gold or 950 platinum ring is complete with a custom-made nesting band that is cut to fit the cluster exactly.\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?
