CASE STUDY: “Dahlia”

Whenever a client requests a custom design commission, we try to get a feel for the aesthetic she likes, as well her habits and fashion interests, so that we can create something that is a perfect fit for her taste and lifestyle. Some come to us with an approximate budget but needing help in working out the right design direction, while others have an exact image/concept that they’d like to bring to reality. When we created “Dahlia,” it was the latter – our client had done tons of research on the type of setting & diamond she wanted, but still required our expertise in refining the idea and envisioning how certain details she wanted to implement would affect the overall look of the ring.


Our first consultation was not in regards to the design of the ring, but determining the parameters of the center diamond that would be its star. We discussed the shape/cut, the budget, and also helped explain to the client how her choices as far as clarity, color, and carat weight and the corresponding grading system and certification would affect the budget. With this information in hand, we were able to narrow the parameters of the diamond search. The conversation continued over the next few days, as we examined our own inventory and searched for options in Manhattan’s Diamond District and other major diamond centers in Antwerp, Hong Kong, Tel-Aviv and Mubmai, where we have exclusive access to stones and pricing not available to the public.

After being in touch about a variety of options, we met again in person to review the selection of diamonds that were handpicked to the couple’s specifications. We offered a small range that included a variety of sizes, qualities and prices so that they could compare and contrast, and make an informed decision.

As a side note, the 4Cs serve as an important guide, but in the end, we believe our clients should have an emotional connection to their perfect diamond – that’s the intangible part of the process, and why we love being able to give clients the opportunity to hold a diamond in their hand, and fall in love with its unique brilliance!

After inspecting each diamond and its certificate, the couple was able to make a decision quite quickly. We purchased the diamond, stored it in our vault and began the ring development & design process.


Our client provided some images of a setting that she particularly liked, but wanted to modify to match her vision. Ryan Jonathan Fine Jewelry She loved the detail and metalwork on the shank of example 1, but preferred that the main diamond be a round brilliant-cut, surrounded by a halo of pave, like example 2. She also wanted the space under the diamond basket in example 2 to be filled with graduated diamonds, like example 1. We started with a “Frankenstein” mock-up combining the two styles for review, and she gave us the go-ahead to proceed.

With an informed understanding of our client’s vision, we created our initial sketches in CAD.

Since the CAD drawing is incredibly realistic and viewable from all angles, we were able to easily collaborate on the next round of feedback. Some adjustments included modifying the curve of the supporting row of diamonds on the shank to be more rounded in order to accommodate a thicker middle row. She also decided that she wanted engraving on the entire ring, so that it could be seen from all sides, and asked us to make a recommendation on the engraving style, as she wanted something different from her original examples but that felt cohesive with the overall effect.

Ryan Jonathan Fine Jewelry

Once we had implemented these design changes, she loved the results, but asked for a final change, that the prongs supporting the center diamond be “claw” style, rather than flat, for a more vintage feel. However, when we raised the concern that this style, usually reserved for very high-carat stones, might obscure the diamond a bit, she deferred to our expertise and went with the flat prongs.


When the final concept was approved, we moved on to the production process. Although the CAD images are an extremely useful technology, we like to go the traditional route when it comes to production, which means sharing a wax model of the design before the final piece is created. Our client was able to try the ring on, and directly experience the proportion and dimensions of how the style would look on her hand.

Once approved, we sourced the accent stones, cast the ring, and an expert setter hand-set each of the diamonds. This process usually takes 1-2 weeks depending on the client’s schedule and needs. We prefer to take our time to prevent errors and ensure that every detail has been attended to and double-checked. So when the moment arrived*, and the bride-to-be tried on the final product of several weeks of collaboration, trust us, it was priceless! Ryan Jonathan Fine Jewelry Nothing compares to helping someone create a custom piece of jewelry, and seeing their face when reality exceeds all expectations – it’s why we are so passionate about what we do at Ryan Jonathan Fine Jewelry.

*In this particular case, our clients weren't in a hurry to have the finished ring, but they were anxious to get engaged and make the announcement to their loved ones. We worked with the groom-to-be to select a classic diamond halo ring on consignment that he could use for his highly anticipated proposal. Soon afterwards, the custom design was ready to be picked up and the consignment ring to be returned. However, they loved the consignment ring and the memories it conjured, so they decided to purchase it as well. Now the bride has 2 gorgeous Ryan Jonathan diamond engagement rings – one for everyday, and a simpler, more modest alternative to wear when traveling or active. In the end, a win-win for everyone!
