BuildARing is an innovative app designed for customizing engagement rings by integrating both lab-grown and natural diamonds from any marketplace or supplier in real time. It offers users the flexibility to combine these diamonds with a variety of semi-mount settings, recommended by the app based on the diamond's shape, carat weight, and other parameters. Alternatively, users can start with a setting and receive compatible diamond shape recommendations, enhancing the custom ring-building experience. This functionality is seamlessly integrated with Shopify websites, allowing for easy management of diamond markups based on carat, price range, and supplier. The app's intuitive 3-step flow enables users to begin their custom design process with either a diamond or a setting, according to their preference. With seamless integration with your store’s shopping cart, BuildARing enhances the jewelry shopping experience by offering a highly personalized service.
