Facts & Questions


Each piece of Daria de Koning jewelry is made in limited quantities of 18k gold or sterling silver. Many pieces are made-to-order, often allowing one to individualize a design. If the item you desire is not in stock, please allow 3-6 weeks for production. Rush orders can often be accommodated, but require an additional fee of $250.

Custom Work
Daria offers custom design services, stone brokering as well as resetting of customer-provided stones. The studio is in the Tribeca area of Manhattan and we welcome customers to meet us to discuss custom work. Custom settings generally start at $3,000.

How does it work?
All of Daria’s engagement rings are created for and with the input of a specific client, either fully custom or semi-custom. The process begins with looking at a variety of diamonds or colored gems that match within your price range. After you pick a beautiful stone, we work out a design together. Then Daria and her close team of artisans build the perfect piece!

Do I need to come in with a design idea?
Not necessarily. Daria is there to help you with this and work through your ideas, but it’s always a good beginning to start the process by gathering different designs and having a notion of what you like. Look online, at retail stores and magazine ads to try and get a handle on one or two styles. Once you come in Daria has books of culled images you can look through and work with.

What if I can’t make it to New York City to see you?
It is best to be able to come in and see things and discuss in person, but digital photos and email work wonders.

How do you find a particular diamond or gemstone just for me?
Daria’s years in the industry have given her access to the diamond and precious stone market through an extensive network of dealers and cutters.

How is your pricing?
Pricing of the rings depends in large part on the size, type and quality of stone the client selects. As a certified gemologist, Daria works with you to source stones in accordance with your aesthetic and budget. Each custom ring itself is made by hand, one piece at a time, tailored to each individual stone. Hand-made, custom settings begin at $3,000.

What about payment?
When we meet, there is a required, non-refundable deposit of $500, which can be applied towards the purchase price. The full price of a diamond or gemstone purchased from us is payable in full before the start of a custom engagement ring order. Otherwise, depending on the order, a minimum deposit of 50% is required.
We consider your order to be formally placed when your work order is signed and we have received your deposit.

What is the timing/how long does it take to have a ring made?
All Daria de Koning jewelry is handmade, one piece at a time with a great deal of care and attention. Turnaround time depends on the time of year, but is generally 4-5 weeks, starting when we have received a deposit, sizing information and any client supplied materials.  A rush option is also available.
