Large pendant with natural Green Precious Opal gemstone origin - Australia gem size is 14 x 23 mm pendant length - 1.37 in / 35 mm pendant weight - 4.9 grams An 11-carat Australian crystal opal takes centre stage in this silver pendant, its luminous surface revealing a shifting play of green and blue. The softly rounded oval form and restrained bezel setting allow the natural character of the gemstone to define the piece. The opal is natural and untreated, with no stabilisation or enhancement beyond polishing. It is a solid opal, not a doublet or triplet. The setting remains open at the back, revealing the stone’s natural, unpolished reverse. The silver is finished by hand with a deeply textured matte surface. After the opal has been secured in its bezel and carefully protected, the jeweller uses a specialised metal burr to create the distinctive scratch finish. The fine, irregular marks catch the light softly, complementing the opal’s fluid flashes of colour. Its balanced proportions lend themselves to different ways of wearing: close to the neckline on a chain of approximately 45 cm, or lower on the torso on a longer chain of around 70 cm. Characteristics • Gemstone: natural Australian crystal opal • Opal weight: 11 carats • Treatment: none; polished only • Construction: solid opal, not a doublet or triplet • Metal: silver • Setting: bezel with an open back • Finish: hand-applied, deeply textured matte finish The necklace comes with a silver chain. Worldwide shipping from Berlin, Germany. Prices include all taxes, valid in Germany and in European Union countries on the Customer's order date. Price does not include import taxes...
