The word carat derives from the word carob, a Mediterranean seed, which has an extremely consistent weight for measuring. The greater the carat weight, the rarer, and more valuable the diamond becomes. Five metric carats weighs exactly 1 gram. Some people want the largest diamond possible.

So happy I chose to go to Nesemanns Diamond Center to get my wedding ring repaired. The entire prong and diamond broke off and I was hesitant to repair it. I spoke with Alex and I felt assured that my 30 year old ring was in good hands. My intuition was spot on!!! What a beautiful job he did!! My ring never left the store as Alex does his own work right there at the store. So glad I chose to go where my husband bought the ring. Thank you!!!!

Nesemann's Diamond Center is extremely accommodating and is always willing to go the extra mile for their customers!
I had a short timeline to purchase a piece of jewelry as a gift for a baptism (under 24 hours notice for the jeweler!) - Alex Nesemann customized a necklace for me and dropped it off at my house so that it would be ready the next day when I got home from being out of town, to take to the event that day!
Extremely impressed with the customer service and their options!

My husband chose the best possible place to buy an engagement ring!!! I have the most beautiful ring & wedding band that I've ever seen and have had the most amazing service at Nesemann's over the last 4 + years! They have been great with cleanings, small repairs/sizings, etc. and even hand delivered my ring next door at the hair salon after a cleaning/adjustment. I am so thankful my husband chose a local friendly jeweler rather than a big box store. I couldn't be more thankful for the service I have received over & over again! Thank you Nesemann's!!

Alex is the BEST! I am so glad I went to Nesemann’s during my search for an engagement ring because Alex was extremely helpful and honest about what I was looking at. To be honest I didn’t really know what exactly I wanted or even much about diamonds or rings in general and other jewelry stores I went to prior were not helpful and just wanted to sell me anything. Nesemann’s was completely different. Alex knows his stuff and explained what I was looking at, how to get the most bang for my buck and worked with me to pick out and design the exact ring I was looking for. Going back to him for

Working with Alex has been such a wonderful experience. He's professional, trustworthy, easygoing and most of all a great jeweler. He turned jewelry I couldn't use anymore to some of the most beautiful pieces. Thank you again.
