UpscaleNation  Customer Service is exceptional! He's always gone out of his way to make sure every detail is taken care of. I had our wedding ring designed and created over 7 years ago and he's taken care of the ring when ever we needed it to be looked at!  The craftsmanship is second to none!

The exquisite work of upscaleNation transcends jewelry; it is a concept. Expensive yes, but not nearly so expensive as it should be. If endearing the love and good will of others can be gained through material means, rest assured there is no better way to do so than through the Isaak collection. Immensely satisfied, and you will be too.

Doron helped me in ways that I cannot describe. I had just an idea of something and he made it a reality. I cannot recommend him more highly. He is patient and over delivers.
Go with him you can't go wrong

My fiancé went to Doron for my engagement ring. He was referred by a colleague. He can't speak highly enough of the quality and service he received on every level.

One initial point of concern was that we live in NYC and Doron is on the west coast. This proved to be no obstacle to the communication, which was seamless and efficient. My fiancé did not feel the distance in the least.

The diamond Doron sourced was superb beyond all expectations.

My fiancé provided Doron with a specific design that he had in mind for my ring. It was a challenging design for a delicate rose gold band inlaid with pink diamonds of a specific size. Doron delivered a meticulously crafted ring far better than anything my fiancé anticipated.

The ring is a work of art of exceptional quality. I am extremely thrilled with it and receive compliments on it regularly.

Throughout the process, Doron was exceedingly patient with my fiancé. He quickly realized that my fiancé expected to have significant input on the design and creation of the ring. He rose to this challenge, communicating and consulting regularly with my fiancé. Doron made my fiancé feel comfortable to ask him questions and provide him feedback during the entire three months that it took to create and finish the ring. Doron responded to all of my fiancé's requests and continues to advise us on questions we have about how to take care of the ring.

We will continue to work with Doron in the future for whatever jewelry we need. We do not hesitate to recommend Doron to all of our friends. We feel very fortunate to have found him.

My brother-in-law and I have been customers of Doron for 5+ years. You will have a hard time  finding a designer more knowledgeable, more talented, and more affordable for the quality of work that Doron offers. Since Doron stands behind his work he offered to us maintenance on our rings for the four of us. He was even able to do it during the crazy holiday season. Go see Doron you will not regret the service, quality, and prices.

Ever since my husband and I got together we have never purchased a piece of jewelry for ourselves anywhere but from UpscaleNation. Not only does he design the most incredible timeless pieces but he also can get any items from major retailers that you want at amazing rates. He makes sure to take care of his customers and has always given us the best advice as to what will be our best options. He listens to what we want and delivers everyone! Never been disappointed.

When it came time to find "THE RING" of my dreams, I excitedly began a frantic search through magazines, went to many jewelry shops, near and far and tried several rings and did endless online searches. The more I searched, the less I found... It became a tedious and discouraging process. I started to get anxious and thought I would end up having to get something I would not be 100% happy with. Wondrously, a friend stopped by our home and she wore a beautiful ring. I instantly fell in love with it and wanted to know where she had purchased it.  She replied that the diamond was her dear, late Mother' and the band was the creation of a Jeweler named Doron Isaak. My friend spoke highly of Doron's work and expressed she loved her ring. Turns out, I loved it too!

My boyfriend called Doron and spoke to him about our interest in a ring similar to our friend's. Doron recommended we meet in his office. He mentioned that he could help get a diamond if we didn't have one.  We brought in our own diamond. 2 weeks before the Christmas Holiday we walked into Doron Isaak's office downtown LA in the jewelry district.  Doron invited us in and we sat down discussed the ring I had in mind while he showed us a few ring samples from his line and this gave us an opportunity to observe the degree of detail and craftsmanship he puts into all his ring designs.

Beyond being a skilled jeweler, Doron is very approachable and professional. He communicated clearly, answered all my questions and ensured he went over the specifics with me such as noting my exact ring size and my choice of metal. He recommended my size should be ¼" smaller so that the band could sit in place allowing the diamond to stay in place.  Doron took all my requests into consideration and covered all the specifics with me and made me feel comfortable.

The Christmas and New Year Holiday slowed production a bit but when I finally opened up that small red box, there, in front of my eyes was one of the MOST exquisite and beautiful rings I've ever laid eyes on.  I couldn't believe it was my ring! It was even better than I had imagined it. I placed that ring on my finger and the fit, the look and the feel is perfect. I own the perfect ring! I get a lot of compliments on it and many people ask where we bought it from.  Thank you to my adoring Partner, our wonderful Lady friend who is so kind so have provided the name of Doron Isaak. Thank You, Doron!

My husband and I have worked with Doron for over 6 years. Beginning with my gorgeous engagement ring (2009) and later another wedding band (2014), Doron has been excellent to work with. Recently, I damaged my engagement ring when my finger got caught on my luggage handle and texted Doron immediately to have it fixed. He responded promptly and went above and beyond to calm my nerves when the ring got lost in the mail on it's way to him for repair. Once the ring arrived he repaired it beautifully and shipped it back to me the next day. I've been unbelievably happy with my rings and highly recommend Doron Isaak Couture Gems!

I've used Doron over the past 10 years and he's exceeded my expectations every time.  He custom designed my wife's engagement ring, wedding band, one year anniversary band, and 10 year anniversary stacked diamond bands.  Every ring was classic, timeless, and unique to meet my very specific requests.  I messed up the sizing of my wife's finger and he re-sized numerous times, free of charge.  He goes above and beyond to give a special, individualized experience.  His clients spend a lot of money with high expectations and he doesn't take that for granted.  I'm very picky and he's been eager to accommodate every request.  I highly recommend Doron for designing high end custom jewelry.

Doron designed my engagement ring and it is the most spectacular ring. He has the highest quality diamonds that sparkle even if they haven't been cleaned in months. I have had a few minor maintenance issues (tightening diamonds, cleaning, sizing, replacing small diamonds on the band) and he has addressed them as soon as I emailed or called and sent it back to me as soon as it was finished with absolutely no issues. I love Doron and will use him any chance my husband will allow! :)

My husband had Doron design my engagement ring and he did the most incredible job! It's an extremely well-made and timeless piece of jewelry I will always cherish it! I even approached Doron when I needed a matching wedding band and he created yet another beautiful ring for me that perfectly complimented my engagement ring. He was a pleasure to work with and I hope to buy more from him in the future.

I needed a special custom bracelet for my girlfriend for her birthday.  Not only did Doron have it ready for me sooner than expected, he went above and beyond setting beautiful diamonds around the band.  His pricing was very fair and he made sure I received the item in a timely fashion.

If you're like me... I knew what she wanted for an engagement ring, but I wanted to surprise her.  Luckily through word of mouth I was referred to Doron.  He made the process extremely easy for me.  I took some examples of settings and he showed me what he had.  He found the perfect stone for the amount of money I wanted to spend.  Let me just tell you, she was floored when I popped the question.  Everyday she is reminded how perfect her ring is by people stopping and asking her where she got it.  And people are impressed when they see the size of the diamond, thinking I spent a fortune..... I didn't.... Please go see this man.  He changed my life-

I was getting pretty frustrated looking for an engagement ring for my fiance'.We had a pretty good idea on the diamond we wanted ,but my fiance' was quite particular about the setting. Luckily we got a referal to this wonderful designer who is strictly word of mouth.Doron spent an entire afternoon educating me about diamonds and another two appointments with my fiance'  to design her dream setting.The workmanship is immpecable.There isn't a day that my fiance' isn't stopped by women who ask to take a closer look at her ring.Since we have sent 2 more couples who also raved about their experiences.Thank you Doron.
