Entscheidend ist das Warum: Eheringe sind das emotional wertvollste Schmuckst\u00fcck \u00fcberhaupt, denn sie sollen ein Leben lang die Verbindung zum Lieblingsmenschen symbolisieren. Trotzdem sind sie nach wie vor gr\u00f6sstenteils unpers\u00f6nliche Massenprodukte. Was fehlt, ist ein pers\u00f6nliches Detail der Ringtr\u00e4ger. Ein Fingerabdruck erinnert zu sehr an Verbrechen. Die Retina dagegen tr\u00e4gt ein ebenso einzigartiges wie unver\u00e4nderliches Muster, verborgen im Auge, das seit jeher als Fenster zur Seele gilt, und wird deshalb weitaus positiver wahrgenommen.","legalName":"RetinaDesign AG","foundingDate":"2023-06-06","numberOfEmployees":{"@type":"QuantitativeValue","minValue":"1","maxValue":"10"},"address":{"@id":"https:\/\/retinadesign.com\/en\/symbol-lexicon\/key\/#local-main-place-address"},"geo":{"@type":"GeoCoordinates","latitude":"47.5590696","longitude":"7.589044500000001"},"telephone":["+41788917989"],"contactPoint":{"@type":"ContactPoint","telephone":"+41788917989","email":"info@retinadesign.com"},"openingHoursSpecification":[{"@type":"OpeningHoursSpecification","dayOfWeek":["Monday","Tuesday","Thursday","Sunday"],"opens":"00:00","closes":"00:00"},{"@type":"OpeningHoursSpecification","dayOfWeek":["Wednesday","Friday"],"opens":"09:00","closes":"18:00"},{"@type":"OpeningHoursSpecification","dayOfWeek":["Saturday"],"opens":"10:00","closes":"17:00"}],"email":"info@retinadesign.com","areaServed":"globally","vatID":"CHE-483.540.767","taxID":"CHE-483.540.767","priceRange":"$$$","currenciesAccepted":"CHF, EUR,","paymentAccepted":"cash, VISA, Mastercard,Twint,Postfinance,"},{"@type":"PostalAddress","@id":"https:\/\/retinadesign.com\/en\/symbol-lexicon\/key\/#local-main-place-address","streetAddress":"Rheinsprung 10","addressLocality":"Basel","postalCode":"4051","addressRegion":"Basel-Stadt","addressCountry":"CH"},{"@type":"ImageObject","inLanguage":"en-US","@id":"https:\/\/retinadesign.com\/en\/symbol-lexicon\/key\/#local-main-organization-logo","url":"https:\/\/retinadesign.com\/wp-content\/uploads\/2025\/05\/250504-Retina-Final-Icon-Colour.svg","contentUrl":"https:\/\/retinadesign.com\/wp-content\/uploads\/2025\/05\/250504-Retina-Final-Icon-Colour.svg","width":599,"height":595,"caption":"Retina\u00ae"}]},"geo.placename":"Basel","geo.position":{"lat":"47.5590696","long":"7.589044500000001"},"geo.region":"Switzerland"},"_links":{"self":[{"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/pages\/32159","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/comments?post=32159"}],"version-history":[{"count":2,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/pages\/32159\/revisions"}],"predecessor-version":[{"id":32838,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/pages\/32159\/revisions\/32838"}],"up":[{"embeddable":true,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/pages\/31297"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/media\/27500"}],"wp:attachment":[{"href":"https:\/\/retinadesign.com\/en\/wp-json\/wp\/v2\/media?parent=32159"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
