A note on production time..... Please read my current production time on this custom piece prior to purchasing- https://www.etsy.com/ca/shop/Specimental?ref=hdr_shop_menu Please note: The rings in the photos have been sold. This listing is for a one-of-a-kind, custom-made opal ring. The opal is in the two final photos. As this is a custom listing, please see my shop announcement for my current production time. This ring will be built around a 11 x 7mm oval shaped solid semi-black opal (shown unset/loose in the photos). The opal is a fantastic play of green and blue, with some slightly pink undertones and shimmers from all angles. The colour play is very strong, and varies in hue according to the type of light you view them in. The photos of this opal were taken outside in strong sunlight. Opals are very difficult to properly photograph, but my opal collection was chosen for their strong, consistent colourplay and gorgeous appearance. I chose my opals from an opal dealer in Australia- they are from Lightning Ridge, where the world's best black opals are mined and cut. If you prefer the darker green/blue opals used in the ring photos, please get in touch- my opal dealer has a very large selection of all size and colour of black opals. The ring is made from recycled gold- the bezel wall and band are 18k, while the bezel platform is 10k. On the ring in the photos, the bezel has been given a brushed texture with a high-shine lip, while the band is hammered and polished. I can also build this ring from 18k white gold, and can give it any finish you like. Photos of custom pieces are always sent for approval prior to shipping.
