I am offering black opal accessories for sale. This time, I plan to introduce a mix of metal types, and the lineup is shown in the last image. This is a black opal ring with emerald green and red flashes emerging from a deep blue. When light is applied, the blue base is clearly visible. This is a handmade, one-of-a-kind piece where the stone was selected and made into a ring. It is recommended for those looking for fine play-of-color pinfire. Opal: 10 x 8.2mm, oval cabochon Setting: k14gf, size 10 (size cannot be changed) *Please purchase only if you understand that scratches and dents are characteristics of natural stones. I have checked them with the naked eye, but there may be oversights. Please forgive me for that. I try to take photos as close to the real thing as possible, but there may be slight color differences depending on the environment you are viewing them in. Shipping is usually scheduled for 2-3 days, but we are closed on weekends and holidays. Since I am offering them at a low price, I only offer a combined discount. We offer a discount of 200 yen for two items, 400 yen for three items, and 600 yen for four items, so please contact me before purchasing. To prevent metal discoloration, we recommend storing them in a resealable plastic bag like a zip lock bag. We also accept changes from regular wrapping to a convenient storage bag, so please write "wrapping for home use" in the transaction message when purchasing. Thank you for viewing. #blackopal #onestone ring #cabochonring #naturalstonering #blackopalring #k14gf Color: Black系 Material: Gold Ring Size: 10
