Services
Jonathan K. and Company Fine Jewelry is a full service boutique jewelry store, which includes a complete offering of jewelry maintenance, repair and restoration, and custom design. Our expert, on-site bench jeweler and staff team to provide professional cleaning and inspection. We know that many fine jewelry pieces are, or will become, family heirlooms, so we take great pride in providing high quality jewelry service.
For the vast majority, purchasing a diamond engagement ring is an occasion that is full of pressure and uneasiness. A number of jewelers in the market use traps and tricks structured to deny you of significant worth and put more benefit in their pockets. Jonathan K. & Co has condensed the knowledge we have gained from working with the largest diamond manufactures in the world.
When most people think of custom jewelry, they think of jewelry created from scratch. Jonathan K. works with each client and sketches a rough draft of the intended design. After the design has been finalized, Jonathan K. will create either a (CAD) computer aided design or a wax model to show the jewelry piece from all available angles.
Choosing the perfect diamond for your engagement ring can be a bit stressful. However, if you approach selecting the right one with the right attitude, it can be a fun experience. For those that wear jewelry regularly, keeping their jewelry clean and looking good requires regular effort.

Ladies': Here's some ammo to help you convince your special Valentine why they would be making a wise and surprisingly practical gift choice this year, if they choose to lavish you with fine jewelry (wink)!During the dark days of winter, the late harvest pomegranate is a sweet and colorful treat.

Jonathan's creativity & attention to detail are totally unsurpassed. My husband lost his wedding ring, which we absolutely loved. Jonathan had come highly recommended by friends. So we explained to him that our first priority was preserving the integrity of the original's aesthetic. Equipped with only three photos & the appraisal description that we'd provided our insurance company, Jonathan crafted an absolutely beautiful, masculine, quantitative & qualitative ring ... far superior to the first! Five stars are too few for this masterpiece & Jonathan's personal

I had the greatest experience working with Jonathan! He's such a great guy and put me at ease when discussing buying an engagement ring, which can be a little stressful for some of us.

For someone with zero experience buying jewelry, he made the process so simple. He took my budget and vague ideas for an engagement ring and designed a ring more beautiful than I could've imagined for my (now) wife.

I am so happy that I didn't just pick a ring "off of the shelf," knowing that her beautiful ring is unique for her means so much, and she doesn't mind the consistent

Wow, we've found our jeweler, could not have asked for more. Knowledgeable, pressure free, excellent customer service.

We needed to set a diamond that belonged to my husband's late mother in an engagement ring. Even though we were not purchasing a diamond from him, Jonathan was beyond helpful. When we finally selected a style, rather than rushing us and having us purchase what was in stock, he ordered the style in a size that would better complement and fit the diamond. When it came time for my now husband to select a wedding band, the style he was after was not in the store; Jonathan

Fantastic group here with classy service - Jonathan, Bethany are top notch and patient. I never felt pressured to buy outside my price point and received a fair price per market at my time of buy. I brought in a stone to have it set as an engagement ring and cannot believe how it turned out. The ring is beyond beautiful and my now fiancé loves it! They followed up with me, and even assisted on insuring and maintaining the ring. The quality of work, jewelry and service here speaks for itself.

I had a great experience over at Jonathan K and Co. I was in search of a chain and was recommended to check him out by a mutual friend. I was very indecisive about which direction I wanted to go with my purchase, but he was very patient and helpful throughout the entire process. He was very persistent in finding the right chain for me, and I am very thankful for that. Highly recommend and I’m already a returning customer.

Jonathan K is a brilliant artist! He created a beautiful necklace replicating my husband's badge. The detail in this piece is unbelievable! Such a treasured piece of jewelry honoring my husband's law enforcement service. I highly reccomend him!

Jonathan swapped out the diamond from my engagement ring from 27 years ago and created a beautiful setting, turning my marquis to an east/west setting and adding accent diamonds around it. The process was very detailed as he created a 3-D printed setting so that we could see how it would rest with my anniversary band and the end result was perfection. Great parking, easy to access, and a phenomenal product!

I’ve known Jonathan since he was in Jr High. He’s been in and around the jewelry business most of his life. He takes his work seriously and has honed his craft to perfection over the last 25+ years. You’ll get quality work with integrity and a personal touch when you work with Jonathan, and you won’t be disappointed.

This is my mom's review she excitedly wanted me to post for her :)

My husband and I celebrated our 50th wedding anniversary on 1/25/19. In commemoration of this anniversary we decided to have a matching wedding band made for my original wedding set. We had shopped around for a jeweler and had decided to entrust the job to Jonathan K & Co. When the ring was done and ready for pick up, we were overwhelmed when we saw the finished ring and what an excellent job Jonathan had done in matching the new band to the old! We have since taken other jewelry pieces for repair, etc. Rest assured

This is the jewerly store you've been looking for. After visiting several stores to inquire about engagement ring cleaning/polishing/sizing, I stopped in Jonathan K and realized I had found what I was looking for. Jonathan's shop is conveniently located, quiet and welcoming, and most of all, free of the hustle and bustle of the crowds typically found at mall stores.

Jonathan and his assistant are courteous, professional, and personable. During my visit I was greeted and welcomed immediately. My needs were discussed and pricing and delivery time addressed efficiently and professionally

Jonathan is amazing. I could not find a ring I liked at any other jeweler. My fiancé and I went to several stores and I feel like I was constantly getting pressured to buy something I did not like. Not Jonathan! He was absolutely no pressure. He listened to exactly what I wanted and we wound up going the custom option. I absolutely LOVE my ring. It is gorgeous. He was also very conscious with our budget and even helped save us money when picking out my diamond. We will be buying from him again!

I've been trying to wait until my wedding band is made to write this review just so I can have the full picture for everyone reading this, but I decided to go ahead and post this now. My fiancé and I found Jonathan on yelp, believe it or not! Based on the good reviews we decided to go in and see him. My fiancé and I weren't finding what I wanted at any other jewelers, so we decided to have Jonathan make a custom ring. Jonathan was extremely helpful and professional throughout the whole process. He listened to me and my fiancé and ended up designing something beautiful and amazing!

First of all, his jewelry showroom is a show stopper. He has the most beautiful jewelry. I paid him a visit because I had lost a small diamond out of my wedding ring. I told him I was hoping to have them back in 5 days because I was leaving town. He stated that he could get them back to me by then. He replaced the diamond, repaired the prong, and flashed (made the white gold look new again) the entire set. Later that evening I get a message from Jonathan stating that my rings were ready for pick up. What???? The next day I went to retrieve my rings and I was floored. They looked brand

I found this place on Yelp and was impressed with the reviews. I took my ring in for a repair and cleaning. Jonathan said it would be ready in about a week, which was a third of the time of another store I called. He does the repairs and cleaning at the store, which was awesome--I didn't want my ring to be sent somewhere. Anyway, I picked it up today and almost started crying when I saw it. It's SO sparkly! It hasn't looked this nice in at least a year. I'm so happy I found this store (Thank you, YELP!). I'll be coming back here for repairs, cleanings, and purchases.

Best jeweler by far! My fiancé had been looking everywhere to buy my dream engagement ring (I'm very picky) and he could not find it anywhere. We ended up hearing about Jonathan through some family that goes to him! Jonathan met with my fiancé the same day he called to get info and they designed the ring together! Jonathan listened to what we wanted and made our vision a reality! You can't beat his quality-made jewelry or his unbeatable prices!! Please don't go to a retail store for your jewelry EVER again! Go to Jonathan K. & Co!!!

Best price, best quality, and no b.s. Jewelry places usually remind me of used car lots. But Jonathan has never pressured me or jacked up the price on me. He even suggests how to save $100 here or there by picking a similar less pricy ring style. Never found a more honest jeweler. Also, his costs are less than the wholesale places. Only downside is not a ton of in-store inventory, but he will bring out his book and build a ring/necklace/whatever for you on the spot. Bought over a dozen pieces over the last 10 years from him (ten year anniversary next week) and every piece has "wowed"

Jonathan is amazing! My fiancé and I had a vision of what we wanted our custom ring to look like, we brought it Jonathan and he created an absolutely stunning piece. We knew we wanted a specific type of diamond (Old European Cut) and we was able to get 3 different ones for us to choose from. We brought some pictures of what we liked and he worked his magic and created a 3D CAD drawing and print of the ring. So cool! He was patient with us and once finalized he brought the whole thing to life. Fantastic! I would recommend Jonathan in a heartbeat!

I'm sure my friends and family are tired of hearing me gush about my new engagement ring, so I'm taking it to Yelp...

My (now) fiance and I visited Jonathan's shop late last year. We looked at some of his sample rings and I brought some pictures of rings I like. A few weeks later he presented my fiance with a rendering of a custom engagement ring and band. After that I was not involved in the process... but it involved several renderings, a 3D wax model, and viewing/examining many diamonds to find the right one. My fiance was very happy with the whole process. Jonathan is not only
