Additional Notes

Complaint: In the time frame of approximately nine months, multiple diamonds have fallen out of the engagement ring. Within the past nine months, five diamonds have fallen out of the engagement ring on four separate occasions. Upon the third time of having the ring fixed, the engraving was polished off during the process resulting in the ring having to stay at the jeweler's for a longer period of time. The company has accommodated us by replacing the diamonds at no charge, however three of the five diamonds that have fallen out were from the same socket, proving that the product itself is defective. Most recently, the ring was taken in on April 12, 2015 (third time, fourth diamond). I was told it would be fixed and returned in one week, but received no phone call. I was called on April 24, 2015 and told the ring was ready. Upon picking up the ring, it was found that the engraving was no longer there. I was told that they so heavily polished the ring that the engraving was polished off, therefore the ring had to stay another day to be fixed. On April 30, 2015 it was discovered that yet another diamond has fallen out. We will be working with a new jeweler to have the ring fixed, because Gemma's Jewelers has proven time and again that they are incapable of producing a quality product.

Desired Settlement: Because we will be working with a new jeweler, we are asking that Gemma's be responsible for reimbursing us for any fees involved with having the diamond replaced, including any handling and/or cleaning fees.

Business Response: Initial Business Response /* (1000, 5, 2015/05/11) */ Firstly we would like to apologize for the inconvenience and disappointment with us. Here at Gemmas Jewelers our number one priority is to keep our customers satisfied. After the complaint was written the customer came to our store and both parties came to an agreement. We will gladly reimburse the customer for their new jeweler costs and hope they will be satisfied with the ring. We assure that our services are available to you at all needs. Respectfully, Gemmas Jewelers Initial Consumer Rebuttal /* (3000, 7, 2015/05/17) */ (The consumer indicated he/she DID NOT accept the response from the business.) Although we are satisfied with the way Gemma's Jewelers has handled our complaint, after speaking with the new jeweler, they will be making a new engagement ring and wedding band and we would like a full refund from Gemma's. Final Business Response /* (4000, 9, 2015/05/28) */ As requested, we will issue a refund for the ring purchased on 09/13/2013, for the amount of $2,000.16. We will request for the ring in question to be returned. Please visit our store to proceed with this transaction. Thank you for your business. Gemma's Jewelers
