The result, opulent and instantly recognisable, left its mark on the 2000s on the Riviera and in Saint-Tropez.<\/p>\n<h2>The signature collections<\/h2>\n<div class=\"fj-seo-table-wrap\"><table>\n<tr><th>Collection<\/th><th>Distinctive feature<\/th><\/tr>\n<tr><td>Allegra<\/td><td>Twisted gold rings in a spiral, the most recognisable<\/td><\/tr>\n<tr><td>Ventaglio<\/td><td>Fan motif set with calibrated stones<\/td><\/tr>\n<tr><td>Boule<\/td><td>Pav\u00e9-set spherical volumes<\/td><\/tr>\n<\/table><\/div>\n<h2>A house that has become rare<\/h2>\n<p>The house ceased its activity in 2020. The pieces are no longer produced and now circulate only on the pre-owned market, which makes them sought after today by lovers of 2000s jewellery. Every piece we offer is appraised in Saint-Tropez and sold with its certificate.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>Is a black diamond a real diamond?<\/h3>\n<p>Yes. It is a diamond whose density of inclusions gives it its opacity. It is worked differently from a white diamond and is harder to polish.<\/p>\n<h3>Can the pieces be repaired?<\/h3>\n<p>The house no longer provides after-sales service. Any work goes through independent workshops, which makes the original condition all the more decisive for the value.<\/p><p class=\"fj-seo-legal\">Francine Joaillerie is an independent house specialising in pre-owned pieces and is not affiliated with any of the houses mentioned.<\/p><\/div>","link":"https:\/\/www.francinejoaillerie.com\/en\/brand\/de-grisogono\/","name":"De Grisogono","slug":"de-grisogono","taxonomy":"product_brand","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/www.francinejoaillerie.com\/en\/wp-json\/wp\/v2\/product_brand\/1060","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.francinejoaillerie.com\/en\/wp-json\/wp\/v2\/product_brand"}],"about":[{"href":"https:\/\/www.francinejoaillerie.com\/en\/wp-json\/wp\/v2\/taxonomies\/product_brand"}],"wp:post_type":[{"href":"https:\/\/www.francinejoaillerie.com\/en\/wp-json\/wp\/v2\/product?product_brand=1060"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
