How it works
1. A complimentary consultation
Your first 30-minute video consultation is complimentary and comes before any deposit. We talk through your ideas, diamond preferences, budget, and questions. Bring a Pinterest board, a photo, or nothing at all.
2. We design it together
Alyssa works with you to bring your ideas to life, developing an initial design based on your style, preferences, and budget.
3. Your proposal & deposit
We send you a personalized proposal with a design sketch and pricing. Once you're ready to move forward, a 50% deposit gets your custom project started.
4. We source your diamond
Alain sources your lab-grown or natural diamond through our trusted partners, walking you through options until you find the right one.
5. You approve the 3D design
We create a detailed 3D design of your ring and refine it with your feedback. Nothing goes into production until you approve it.
6. Crafted, approved, delivered
Your ring is carefully crafted and finished. We send detailed videos for your final approval, then collect the remaining balance. Your ring is shipped fully insured via FedEx, with a signature required.
Most custom projects take about 4–6 weeks from the 50% deposit to the finished ring. See the full timeline.

Questions, answered:
How much does a custom engagement ring cost?
Custom projects start at $3,000, and most engagement rings are between $4,000 and $6,000. The center stone drives most of the price, followed by the metal and the complexity of the setting.
How long does it take?
Typically 4–6 weeks from your 50% deposit to the finished ring. If you have a proposal date, tell us during your consultation.
How does it work if we're not in the same city?
Everything happens remotely. We meet over video, share your design and 3D renderings digitally, send final videos of your ring for approval, and ship worldwide via insured FedEx with a signature required.
I don't know much about diamonds. Is that a problem?
Not at all. Many of our clients start there. We explain what actually matters for your ring and help you decide with confidence. If you want a head start, see the 4Cs of diamonds.
Should I choose lab-grown or natural?
It depends on your priorities. We work with both and will walk you through the trade-offs for your specific ring. There's no wrong answer, only the right one for you.
Do I approve the design before it's made?
Yes. Your design is developed with you, and nothing goes into production until you approve the detailed 3D design. We also send final videos of the finished ring before it ships.
How is my ring delivered?
We ship worldwide via FedEx, fully insured and with a signature required. International customs, taxes, and destination restrictions are handled case by case.
