21 Oct Start Your Custom Engagement Ring Journey in San Diego
Designing your engagement ring should be one of the most exciting, and stress-free, parts of your love story. At C. Blackburn Jewelers in La Jolla, jewelry designer Carl Blackburn makes the process personal, transparent, and beautifully simple.
Below, we share how Carl typically guides new clients through the journey of creating a one-of-a-kind engagement ring, using a couple of recent client scenarios as real-world examples.
Step 1: The Initial Consultation
Every project begins with a personal consultation at our La Jolla jewelry store (or virtually, if you’re out of town). This is where you’ll share your ideas, inspiration photos, and budget. Carl listens carefully, answers questions, and helps refine your vision into a clear direction. The meeting is usually arranged during the week or on Saturady between 12pm and 6pm.
Some couples come in together from the start; others may begin the conversation individually, then bring in their partner later. Either way, you’ll leave with a clear understanding of the creative steps ahead and a general price range — typically between $3,000 and $6,000 for most custom engagement rings, depending on the materials and design complexity.
Step 2: The Design Deposit
Once you’re ready to begin, a deposit of around $500 typically secures your project. This deposit covers the time and expertise required for the initial design work, CAD renderings, and prototype modeling.
As Carl explained in one message to a San Diego couple:
“At this stage I require a $500 deposit to dive into the project for you. The first thing I’ll do is prepare some diamond options and prices for you. Once we get through this diamond selection process and you have chosen your diamonds, I’ll start building the ring design around them and present you with your first CAD video.”
This small deposit ensures that you’re prioritized in Carl’s design queue and begins the exciting process of bringing your dream ring to life.
Step 3: Selecting the Diamond or Gemstone
After the deposit, Carl sources diamond or gemstone options tailored to your style and budget. He hand-selects stones from his national and international wholesale network, ensuring the highest quality and value.
You’ll have the chance to see and compare several stones in person, so you can confidently choose the perfect one.
“I will then have the diamonds shipped in so you can see them in person, compare several options, and make your final choice,” Carl explains.
Once you select your diamond (or diamonds), you pay only for the stones you’ve chosen — Carl immediately pays the supplier on your behalf.
Step 4: CAD Design & Video Presentation
Next, Carl creates a CAD (Computer-Aided Design) model of your ring. You’ll receive a video rendering showing every angle, allowing you to visualize exactly how your ring will look in different precious metals, such as white, yellow, or pink gold, or two-tone gold.
“Once you settle on a diamond, I then create the CAD design of her ring. Attached is a video showing what that looks like,” Carl wrote to another client.
You can request adjustments until the design feels perfect. Carl personally oversees every detail to ensure your ring reflects your unique story and style.
Step 5: Resin Prototype & Final Approval
After you approve the CAD design, Carl can create a resin prototype — a lightweight model of your custom engagement ring that you can hold, try on, and review before production begins. This step gives you extra peace of mind before your final piece is cast in metal.

Step 6: Ring Production & Delivery
Once the design is approved, your engagement ring enters production. Using the traditional lost-wax casting method, Carl’s team crafts your ring in your chosen metal — platinum, yellow, white, or rose gold — and sets your diamonds or gemstones with expert precision.
Most rings are completed within two weeks of design approval. The final balance is due upon delivery of your finished ring.
Why Clients Love This Approach
Clients consistently praise Carl’s straightforward process and open communication. Every step is clearly explained, every cost transparent, and every design treated as a collaboration.
Whether you’re creating an engagement ring together as a couple or planning a surprise proposal, Carl ensures the experience is personal, creative, and joyful — from the first consultation to the moment you open that little box.
A Beautiful Diamond
Carl Blackburn helped me create the perfect engagement ring. He found a beautiful diamond and side stones to my exact specifications at an excellent price, then guided me through the process from start to finish. My fiancé loves the ring, and it was appraised professionally at a value substantially higher than what I paid for it.
Truly Fantastic!
Carl is our family’s new go-to jeweler. He is truly fantastic! Carl is extremely professional and a true expert that knows his craft. He gives honest and well sought after advice and delivers a remarkable product in a timely manner. He patiently guided my fiancé and I through the process of a customizing an engagement ring/wedding band set and we couldn’t be happier. I highly recommend Carl and his shop!
Close Attention
Right from the start the experience with Carl was amazing. He paid very close attention to detail for every step of the process and was more than accommodating to make sure the ring that was custom made for my fiancé was top tier and was exactly what I had hoped for. I could not ask for a better experience for a custom made engagement ring. From the beginning Carl was professional and punctual and takes his skill very serious to provide exactly what you want. 10 out of 10.
I’m Grateful
Yesterday I received an education in gemstones, the jewelry making process and jewelry design! Carl spent 3 to 4 hours of his valuable time with us discussing gemstone identification and value. He was extremely professional, knowledgeable, and patient! I was truly impressed and left his shop with the feeling that he is honest and trustworthy. He would absolutely be my first choice to have a piece of jewelry designed and purchased! I really cannot say how grateful I am for the knowledge he imparted to us! It was well worth the drive!
The Perfect Ring!
My (now) fiancee and I went to many different jewelers on our search for the perfect ring, and while we liked many of the other jewelers, none of them offered anywhere near the personalized service or competitive prices that Carl offers. He made us truly feel at home shopping for the perfect ring. He took the time to explain all of the different options within our price range, including detailed explanations of the ‘three C’s’. He helped us to identify the perfect ring and had it made for us well ahead of schedule. I cannot give him a better recommendation! Do yourself a favor and start your search with him.
A Dream Experience!
Designing our custom engagement ring with Carl was a dream experience! Carl was able to seamlessly combine our desired design elements into the perfect ring at a fraction of the price of other options. He guided us through all of the steps of the process and made sure to check in with us throughout the development. We can’t wait to come back for our wedding bands.
Carl Was Awesome
I brought in a couple of legacy rings with diamonds of different sizes in the summer of 2023 and Carl was able to consult how he would repurpose the diamonds into a design that fit both what I was looking for and on a very reasonable budget. Those diamonds were combined with a new diamond, matching the existing cut, to create a beautiful engagement ring and wedding band that I (and more importantly) and my now fiancee loved. The process included CAD workup of the rings, a wax model, and then the finished product. Carl was awesome throughout and was a pleasure to work with!
Absolutely Stellar!
Had an absolutely stellar experience with Carl at C. Blackburn Jewelers. My fiancé custom designed his wedding band, and Carl made it come to life. His wedding band looks incredible, and we are so happy with the final product. The ring was completed quickly which was very nice. Carl is very informative and kept us updated along the process. I highly recommend, and will come back again!
A Dream of a Ring
Thank you so much, the ring is perfect and she loves it. You literally made the dream of a ring we had in mind and then more!
A Very Unique Ring
Carl was able to help me take a very unique concept of a ring, and work with me step by step create to an amazing final product. Even though this engagement ring was quite unorthodox, Carl was ready for the challenge and absolutely nailed it! My future wife LOVES it. Thank you Mr. Blackburn!
Very Comfortable
Carl made a custom ring that my fiancé and I couldn’t be happier with! He was always professional and responded promptly to emails. He made me feel very comfortable going to him with any revision request and was able to execute exactly what I envisioned. I plan to reach out to him when the time comes to design wedding bands and would recommend him to any and everyone who is looking for an engagement ring!
VIP Treatment
Carl made my platinum wedding and engagement ring. We designed it together and my hubby and I are in love with it! I have brought two friends to him and he is amazing, and gives the VIP treatment every time!
So Helpful & Knowledgeable
I could not recommend Carl Blackburn more. Did a custom engagement ring with him and he was so helpful and knowledgeable throughout the entire process. He’ll never try to upsell you and he’ll work with you until you get the ring exactly the way you want it. We went to a couple big box jewelers before him and you know what they can have all the fancy display cases they want, but they’re not gonna provide you anything close to the type of service and quality and that you get by working with Carl. Highly recommend!
Very Communicative
Carl is simply the finest jeweler in Southern California. I called him in a frenzy a few months before my proposal. I had just received some disappointing renders from a different jeweler regarding the design I had created for my partner’s engagement ring. I was in search of someone who could really create and honor a vintage design. Immediately, I was blown away by Carl’s knowledge, expertise, and confidence in being able to deliver exactly what I wanted to create. His demeanor calmed my nerves and got me excited about the process.
Carl helped me along every step of the way. He was very communicative and responsive and demonstrated his years of experience at every turn. From sourcing and selecting the perfect vintage stone to refining the final design for the ring, every aspect of the process got me more and more excited about the final product. I couldn’t have been more thrilled with how the ring came out, and my partner loves looking at it every day. She couldn’t believe the amount of detail and craftsmanship that Carl was able to pack into a single piece.
There’s no reason to go to anyone else. If you are looking for a great jeweler who can deliver a beautiful and authentic piece at a fair price, Carl is your man!
A Special Feeling
Carl made my fiancé’s engagement ring and it was absolutely perfect! I didn’t know anything about jewelry and was pretty nervous when we started out, but Carl was super helpful and friendly and patient. He helped me understand what I was looking for and it never felt like a sales process with any pressure, but a fun project. He was always transparent about prices and never made it feel uncomfortable.
Carl obviously has a great eye for design, and helped guide me, while still bringing my ideas to life and making it feel like a totally custom process. Most importantly, my fiancé loves the ring (“it’s perfect”) and she gets so many compliments. Having a one of a kind engagement ring like this is a really special feeling, and I’m so happy I chose to work with Carl as opposed to a big chain jeweler. I couldn’t recommend him more strongly!
