For the 925/1000 rhodium-plated silver doublet blue opal necklace, 42 + 3 cm, a rigorous process is followed by Opalook to guarantee your end customers a quality product that complies with standards. The design and prototyping begins with a meticulous creation phase, where each necklace is carefully drawn and examined. The blue opals, selected directly in Australia, are chosen for their authenticity and value. After the prototype is approved, plaster molds are created, in which the 925/1000 silver is melted and poured to form the base of the necklace. Each manufacturing step is subject to detailed inspection and precise finishing. The necklaces are hallmarked to authenticate the quality of the silver, including hallmarks specific to the metal and the importer. A rhodium plating treatment is applied to ensure a shiny and durable finish, protecting against oxidation. Each necklace comes with a certificate of authenticity and an information leaflet, attesting to our commitment to quality and transparency.
To ensure the durability and shine of the necklace with blue opal doublet in rhodium-plated silver 925/1000 (42 + 3 cm), it is essential to pay particular attention to the maintenance of the natural stone. At Opalook, we advise professionals and resellers to keep these jewels in individual bags or dedicated boxes to avoid friction and potential shocks with other pieces in your collection. For cleaning, a soft cloth soaked in cold water and dishwashing liquid is ideal for maintaining the shine and beauty of the opal's reflections, thus ensuring an optimal presentation in the window.

Data sheet
At Opalook , we specialize in Australian opals, which represent 95% of the world's opals. The blue opal doublet, featured in this 42 + 3 cm 925/1000 rhodium-plated silver necklace, is particularly prized for its fascinating play of light and multi-colored reflections.

Opals form from silica spheres accumulated in rock cavities, creating captivating reflections when light passes through them.

At Opalook , we offer doublet opals, reinforced with a support of parent rock to intensify their brilliance. Each opal is carefully cut into a cabochon, highlighting its multi-colored reflections and making each blue opal doublet necklace as unique as it is precious to your customers.
