Size: 6 Weight: 6g Carved Jet Solitaire: 6/8" x 1/2" Frame Around Jet: 1" x 6/8" Hallmark: None Condition: Excellent Vintage Condition As it is preferable to most vintage/antique jewelry collectors that older pieces maintain their patina I don't polish vintage/antique pieces. However, if you prefer to have the ring polished, please let me know and I will shine it up before I mail it to you. It is extremely important to me that you are satisfied with your purchase, so, if the ring is not as described, please contact within 5 days of receipt (I cannot process a refund if you do not contact me prior to any return) and return it to me in the same condition as it was when I send it to you, and I will happily refund your payment, including original S H. As with any pre-owned items, there may be signs of age. I do my utmost to take and present photos that accurately depict the item for sale, including any blemishes/damage. If you have any questions prior to purchase, please let me know and I will get back to you asap. I cannot offer refunds for buyer's remorse, failure to read terms or descriptions, or for not asking questions not answered in the listing. S H charges for places outside of the 48 contiguous United States will be calculated based on the weight of the package. I will always combine shipping costs whenever possible. Should the extra item not add to the cost, then there will not be any extra charge for combined shipping. Thank you for taking the time to visit SoVintageous, please drop by again.
