950 silver pendant decorated with an original 8.4cts Australian black opal sculpted with bright blue and green reflections. Unique creation handmade in my workshop and stamped with my master stamp. Dimensions (excluding the ring): 2.7 x 1.4 cm The carved black opal that adorns this silver pendant comes from Australia. It is a natural stone, which has not undergone any treatment. Pendant sold alone, without chain. To preserve the appearance of silver and not to damage the stone, I recommend that you remove your jewelry for any prolonged swim (shower, bath, pool, sea, etc...), as well as to practice a sporting activity. However, the color of the metal may continue to change over time, in which case gentle cleaning with a chamoisine or cloth and a little warm water and soap, followed by drying in the open air, will restore its shine. Do not hesitate to contact me if you want another method of delivery.
