I ordered a fancy pink diamond. Waited weeks for its arrival just to find an empty ring box and a certification paper for a different diamond that what I purchased. I contacted them to send me my diamond ASAP. They are putting in a claim with there insurance for the loss of a diamond they didn't even ship and are telling me I cannot get my refund or a diamond shipped until they get paid from insurance. Not impressed at all. Scam alert.

Hello Edward,
While we are still waiting on a resolution from FedEx, I wanted to address your comments in the review above.
Per our previous correspondence, we can confirm the Fancy Pink diamond you ordered from our Portland, OR office was shipped to the Australian address provided. This means at some point during the shipping process, either while being transported via FedEx or when going through customs, the stone had to have been removed. In the history of our company, this has never happened with a domestic or international order so we are currently working with our shipping provider/insurance company as well as FedEx to get this resolved for you in a timely manner.
Since leaving your review you have placed a number of orders on our website, and we are sorry that we are not able to process these orders; as I am sure you can understand, we need to get this situation resolved before we are able to ship out any more products to you.
We are pushing to get this resolved within the next 10 days through FedEx; because you will not provide us with your phone number, there have been delays in the process, however once FedEx is able to close the investigation we will issue a refund. We appreciate your patience and will continue to keep in contact as the investigation progresses.
Kindest regards,
Linley Shepard

Hi Joshua,
I’m very sorry to hear you’re not happy with the Diamond Hybrid®. We pride ourselves on being extremely transparent regarding our technology; we clearly describe the Diamond Hybrid® here - http://www.miadonna.com/t-diamond-hybrid.aspx, here - http://www.miadonna.com/t-choosing-a-diamond.aspx, and directly answer your question "Will the MiaDonna Diamond Hybrid® test positive on a traditional jeweler’s diamond tester?" here - http://www.miadonna.com/t-faq-will-hybrid-test-positive-on-tester.aspx. With all of this information clearly provided throughout our site, I’m confused as to why and how you feel we’ve misrepresented the quality or make-up of the Diamond Hybrid®.
With regards to your return, my apologies for the delay. I’ll look into this first thing Monday and will get back to you with a status update.
If you’d like to discuss anything I’ve stated above, please feel free to contact me anytime.
Kindest Regards,
Andrew.

Poor quality product
Purchased a diamond and after 2 year, the diamond looks like a cubic zirconium diamond. MiaDonna reassured us that it would be covered under one of two warranties. After sending it to them, they could not repair it and stated the quality is my fault, normal wear was not covered in their warranty. They offered to replace the stone, but for a cost. When I told them I was not happy with their service, they threatened to take legal matters against me if I expressed my opinion of the poor quality product I bought.

Hi Theresa,
Thank you for taking the time to leave us your feedback. I’d like to apologize that you did not, in your opinion, receive the service or product quality we’re known for.
I’ve taken the time to read your review to ensure I have all the details correct. I also spent this morning with our Personal Shoppers to gather the facts regarding your order, reviewing email logs and order notes, in an attempt to see where we went wrong and how we can remedy the issue at hand. As a company we take immense pride in our customer service, so even the smallest issue is scrutinized over.
I am afraid in this instance, I am behind my team’s decision entirely. Here's why:
We stand behind our product, which is why we offer our Lifetime Guarantee on the Diamond Hybrid® center stone. Under this guarantee, we will without question cover any color change or chipping due to manufacturer defects, as seen by the naked eye, for the life of the Diamond Hybrid in ordinary conditions. Just as with any natural Ruby, Sapphire or Emerald gemstone, normal wear and tear is excluded and should be expected. While the Diamond Hybrid is incredibly hard, it is not indestructible, therefore it must be treated with a level of care. This guarantee is clearly communicated on our website: http://www.miadonna.com/t-guarantee.aspx.
We also provide complimentary cover against accidental damage so you never have to pay full price for a replacement stone if accidental damage were to occur. Had your stone chipped or changed color/clouded internally, it would have been immediately replaced.
In the case of your center stone, it was evident upon inspection that the stone itself had been severely abraded on the external surface, damage that can only be caused by excessive rubbing and/or scraping. Further more, your ring had visible evidence of significant wear on the metal either side of the center stone. While the scratches on the ring could be removed through polishing, this is not something our guarantee will cover. However, I did see that we offered to complimentary polish the scratches out during the center stone replacement.
I'm afraid I cannot find any fault in the way in which this case was handled. The emails from my team were sincere, understanding, accurate and detailed. We even took the time to photograph your ring to help visually communicate what we saw and why this damage wasn’t covered under our guarantee.
As for your comment regarding "threats" being made, this statement is not accurate. I’ve included the exact exchange for future readers to review:
You: “If the warranty does does not cover a replacement of the stone, please return my ring and I will make sure that I do everything to make your future customers aware of the poor quality and warranty service MiaDonna has shown me.”
MiaDonna Personal Shopper: “Regarding your comments on making sure future customers are aware of the poor quality and warranty service, would you like me to have the MiaDonna General Manager contact you to discuss these threats? If so, I would be happy to forward your information along to him.”
We encourage honest reviews and opinions and believe in 100% transparency for all consumers. Your opinion, favorable or not, is your opinion, however stating that we threatened legal action is simply not true. From the email exchange, it actually sounds like you are the one providing us with an ultimatum (or threat).
I'm really sorry it has come to this online exchange, and if I’ve misinterpreted any of your review, please feel free to contact me anytime on 503.336.1581.
Kindest Regards,
Andrew.

Great customer service, problems with product
The customer service experience was excellent. Though, within 24 hours of my wife wearing the ring two stones fell out of their settings. Mia Donna is fixing this problem free of charge but this is disappointing to say the least.
Response from MiaDonnaMay 18, 2015
Hi Eric,
I'm really sorry to hear this has happened. We handcraft every item to the highest industry standards, so it is extremely uncommon for a ring to loose two stones at once. Regardless, we will inspect the ring once received and reset the stones immediately.
Again, I apologize for this inconvenience and do hope our customer service and your new MiaDonna ring ("take-two") will inspire you to update our star rating.
Thank you again for shopping with us; we will be in touch as soon as your ring is received.
~ Andrew (General Manager)
