In motion, the stone reveals differentiated light guidance that particularly emphasizes the architectural faceting.\u003c\/p\u003e\n\n\u003cp\u003eThe spinel has been \u003cstrong\u003eprofessionally re-polished\u003c\/strong\u003e, visibly optimizing symmetry and surface precision – an intervention that significantly strengthens the clarity of the lines and the overall effect of the cut.\u003c\/p\u003e\n\n\u003cp\u003eGemologically, it is an \u003cstrong\u003euntreated spinel (no indications of heating)\u003c\/strong\u003e, confirmed by independent examinations from \u003cstrong\u003eLotus Gemology and ICA GemLab\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eDuring the analysis, Lotus noted \u003cstrong\u003eminor external residues from the polishing process (FF-01)\u003c\/strong\u003e. This is a \u003cstrong\u003esuperficial, non-structural finding\u003c\/strong\u003e that neither affects the stability nor the intrinsic value of the stone but can occur in the context of precise re-polishing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRubra Structura\u003c\/strong\u003e represents a minimalist, substance-oriented interpretation of red spinel – less effect, more depth.\u003c\/p\u003e\n\n\n\u003c\/div\u003e","brand":"Character-Gems.art","offers":[{"title":"Default Title","offer_id":58033059529078,"sku":null,"price":3401.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/3018\/3030\/files\/rubra-structura-1696635.jpg?v=1780698441","url":"https:\/\/character-gems.art\/en\/products\/rubra-structura","provider":"Character-Gems.art","version":"1.0","type":"link"}
