A Repeat Customer

As a repeat customer I can say that it was with high expectations that I placed my third order with your company for my 14K Gold Badge Pendant as you have always produced high quality work. I just received my pendant today and I am blown away with how amazing it looks. The quality of the craftsmanship and the eye for the slightest detail is outstanding. Having purchased this same pendant in sterling silver I knew what a quality product you guys produce, but this 14K Gold version is spectacular. The gold and the black highlights just make the entire piece “POP”.

Great job again and thanks for this amazing piece!

I Thank You With All My Heart

I am at a loss for words (as I’m sure you have heard many times) for the touching gift of my husbands badge pendant. I was looking for something special in a remembrance to wear close to my heart and you fit the bill perfectly. I’m sure you know how special you make the families feel with your sentiment of jewelry. I would like to know if it’s possible to buy more and the cost to send them. My daughter and grandkids would like to have one too. You are truly special for making this happen. I thank you with all my heart.

Bless You.

Thank you from the bottom of my heart

I would like to thank you again for honoring Police officers killed in the line of duty, especially here in Georgia… I hope you know how much you help families heal by wearing the jewelry you make to honor their officers… I absolutely love the earrings you made for me. Again, I just wanted to say thank you from the bottom of my heart.

Beautiful Pendant!

…thank you for your generosity. After the events of 12/13/03, it became difficult to trust that there is any good left in mankind. It means more than I can express to know that there are still some great people out there, as you are a shining example of that fact.

Amazing Attention to Detail

HI.. I just wanted to let you know that I received my pendants… THEY ARE BEAUTIFUL!!! I couldn’t be more pleased on how they turned out. The detail is amazing. I gave her the pendant last night….she was so touched… she cried. She told me that everybody at the department will be jealous… because nobody has anything like it.. and she will be the first one to wear a department pendant. Thanks again for your GREAT customer service and your attention to detail.
