    The best experience

    The jewelry industry is full of pretentious and snobby sales people. We've experienced it too, and it's just unacceptable. Buying special things should feel special.

    There is a reason why we call Barbara and Nicole our "sweethearts." Your experience will be warm, comfortable, and educational whether through e-mail or in-person.

    Lifetime Care Plan Available

    "Lifetime warranties" are often very limited to what the makers agree is their fault. We believe our built-in warranty is stronger, and our add-on care plans are the best in the industry.

    You can purchase a genuine lifetime warranty though the highest most trusted jeweler insurance company in the world for over 100 years. Purchase it with your ring order, and you will be covered.

    You receive digital mockups before purchase to make sure that you are 100% pleased, and feel educated, guided, and secure in your purchase.

    Client Testimonials

    Midwinter Co. provided an excellent experience when shopping for an engagement ring. I was able to customize it exactly how I wanted it and their stones and settings are so unique, I knew I was getting something one of a kind. Working with them via email was very easy and quick. They were incredibly responsive and helpful with suggestions. We are both blown away by the ring and so happy we picked Midwinter Co. We'll be coming back for the wedding bands soon!

    Midwinter Co.'s customer service and quality craftsmanship is amazing. My fiancee loves her ring and is so happy with the unique look and the company's mission statement. Samantha was very kind and great to work with throughout the entire process. I was nervous ordering something so important online but she was very accommodating and super helpful.

    When searching for engagement rings online with my fiancé, the only request that I had was that it come from Midwinter Co. All of their rings are so unique and stunning. When I received my engagement ring, it’s beauty in person was indescribable. I am so happy with my one of a kind, gorgeous product. Everyone always asks me where my ring came from and I never hesitate to tell them, Midwinter!


    I ordered a ring from Midwinter Co. right before Christmas only to find my partner had already bought me something similar. I was able to email and cancel my order without any problems, even over the holidays. Samantha was very understanding and easy to work with. In terms of professionalism and attentiveness, I highly recommend this shop.

    ...Initially, I was concerned about the timeframe because it was a custom job. I ordered the ring about 2.5 weeks before Valentine’s Day, but I wanted to ensure it would arrive before Feb. 14th. So, I emailed Midwinter Co. in order to expedite the process. I ended up receiving the ring within one week of purchasing it! I was thrilled. I also sent the ring back to be resized and that process has been prompt and user friendly. I will definitely purchase again from Midwinter Co.

    My boyfriend and I recently got engaged at the end of last year and he proposed with the most beautiful ring (the black celestial square cut diamond)! It is so breathtaking, so classic, yet unique. I get compliments on it all the time. I love that it's from a small family business and not mass produced. Every time I look down at my hand, I can't believe that it's my engagement ring! Thank you again for all your beautiful work!

    Jennifer & Douglas

    I adore Midwinter Co! I have followed them for many years and knew early on that they were the ONE for me. I’ve ordered things personally, and of course, my engagement ring is made by them. I love how purposeful and thoughtful they run their company. Such genuine and kind individuals. Looking forward to ordering our wedding bands later this year!

    The customer service was spectacular. They helped me the whole time to find a beautiful ring that I loved. They listened to al of my wants and produced something that my fiancée and myself loved. It was beautiful and I would recommend to anyone.

    Steven S

    There aren't enough words to describe how amazing these two are with putting so much effort into the quality of their jewelry. I have an engagement ring from them and to say the diamond sparkles is an understatement! It's literally the shiniest thing I ever laid eyes on. Not to mention how hands are they are. Samantha answers all of my emails (as I'm resetting my ring and getting a wedding band from them too!) I recommend them to literally everyone! Support a small business and most importantly, support great work! Thank you, Midwinter Co, I truly don't think I would have a diamond if it wasn't for you.
