Purchased at the Poland Pavilion at the Osaka-Kansai Expo. A ring from the Polish amber brand S&A, featuring a bee design. This is a one-of-a-kind piece, each with a unique brilliance. This particular ring features a stunningly beautiful green amber. I hope you like it. I am including the bag and certificate I received at the time of purchase. They only gave one set per person, even if you bought multiple items, so I'm including them with this, the most expensive item. I will also include the card given to visitors of the Poland Pavilion. The size is not exact, but the inner diameter is approximately 17.7mm, which I believe is around a size 15 (Japanese size). Please allow for some error as this is measured by an amateur. Please be aware that overseas products may have scratches or dents due to manufacturing or transportation. Also, please refrain from purchasing if you are very sensitive, as this item has been stored at home. Thank you for your understanding. No discounts or returns, please. - Brand: S&A - Accessories: Purchase bag, green certificate, card - Design: Bee motif - Material: Silver - Stone: Green Amber Thank you for looking.
