Their offset curves frame the horizontally mounted diamond without adding a halo or shoulder stones.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow much coverage do the prongs and bypass shoulders give the marquise?\u003c\/strong\u003e\u003cbr\u003eA rounded prong sits over each marquise point, and two additional prongs hold the sides. The curved shoulders do not form a continuous metal enclosure; sections of the edge and the faceted top remain exposed. Protect the setting from hard knocks and remove the ring for lifting.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan a straight wedding band sit flush beside the curved marquise shoulders?\u003c\/strong\u003e\u003cbr\u003eThe bypass section widens to an estimated 2.0–2.5 mm and curves around the horizontal center. A straight band’s fit depends on clearance along those curves, not just the 1.50 mm lower shank. Compare the completed rings to check for contact with the prongs or diamond.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow do I clean the joins between the bypass shoulders and the four prongs?\u003c\/strong\u003e\u003cbr\u003eThe four rounded prongs and curved shoulders create separate metal-to-stone junctions around the horizontal marquise. Use warm water, mild soap and a soft brush to clean those areas, then rinse thoroughly and pat dry without pulling cloth beneath the rounded tips.\u003c\/p\u003e","brand":"Signora Jewels","offers":[{"title":"Silver","offer_id":67657623503008,"sku":"SJ\/DR\/LGRG0908\/S","price":321.0,"currency_code":"USD","in_stock":true},{"title":"10K Yellow Gold","offer_id":67657623535776,"sku":"SJ\/DR\/LGRG0908\/10KY","price":567.0,"currency_code":"USD","in_stock":true},{"title":"10K White Gold","offer_id":67657623568544,"sku":"SJ\/DR\/LGRG0908\/10KW","price":567.0,"currency_code":"USD","in_stock":true},{"title":"10K Rose Gold","offer_id":67657623601312,"sku":"SJ\/DR\/LGRG0908\/10KR","price":567.0,"currency_code":"USD","in_stock":true},{"title":"14K Yellow Gold","offer_id":67657623634080,"sku":"SJ\/DR\/LGRG0908\/14KY","price":786.0,"currency_code":"USD","in_stock":true},{"title":"14K White Gold","offer_id":67657623666848,"sku":"SJ\/DR\/LGRG0908\/14KW","price":786.0,"currency_code":"USD","in_stock":true},{"title":"14K Rose Gold","offer_id":67657623699616,"sku":"SJ\/DR\/LGRG0908\/14KR","price":786.0,"currency_code":"USD","in_stock":true},{"title":"18K Yellow Gold","offer_id":67657623732384,"sku":"SJ\/DR\/LGRG0908\/18KY","price":1059.0,"currency_code":"USD","in_stock":true},{"title":"18K White Gold","offer_id":67657623765152,"sku":"SJ\/DR\/LGRG0908\/18KW","price":1059.0,"currency_code":"USD","in_stock":true},{"title":"18K Rose Gold","offer_id":67657623797920,"sku":"SJ\/DR\/LGRG0908\/18KR","price":1059.0,"currency_code":"USD","in_stock":true},{"title":"Platinum","offer_id":67657623830688,"sku":"SJ\/DR\/LGRG0908\/PT","price":870.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/3033\/2320\/files\/WhiteMetalEast-WestOvalDiamondRing_1.png?v=1791367532","url":"https:\/\/signorajewels.com\/products\/marquise-cut-lab-grown-diamond","provider":"Signora Jewels","version":"1.0","type":"link"}
