I. Design & Diamond Excellence
Can I design my own custom ring from scratch, or do I have to pick a preset style?
Yes. You can start completely from scratch. Whether you have a clear vision, a rough sketch, or Pinterest inspiration, our lead designers will work with you 1-on-1 to create a custom CAD model and bring your ring to life. You can also customize any of our existing settings with your choice of metal and stone.
Do your diamonds come with official certificates?
Yes. We specialize in lab-grown diamonds. Every diamond purchased from us comes with an official certificate from the IGI (International Gemological Institute), which grades its cut, color, clarity, and carat weight.
II. Value, Sourcing & The Custom Journey
Why choose CBT Diamonds over traditional jewelers?
As an independent direct-to-consumer brand, we avoid traditional middleman markups and retail store overhead. This lets us offer quality craftsmanship and IGI-certified lab-grown diamonds at significant savings compared with traditional retailers.
Are your diamonds ethically sourced and eco-friendly?
Our diamonds are grown in a laboratory rather than mined. We take care to work with responsible suppliers.
How long does the entire custom process take from design to delivery?
The standard custom ring timeline is approximately 2 to 4 weeks from design approval to final delivery, including 3D CAD modeling, hand-crafting, quality checks, and insured shipping.
III. Peace of Mind: Sizing, Shipping & Policies
What if I don't know my partner's exact ring size?
You can find the size with our string measurement guide, or order a physical Ring Sizer Kit. The Ring Sizer Kit is offered through our Deposit Now, Credit Later program, and the deposit is fully credited toward your jewelry order. We also include one free ring resizing within 1 year of purchase.
What are your return and warranty policies?
Because custom pieces are made to your specifications, custom orders are non-refundable (we provide unlimited 3D CAD design reviews before crafting). Standard items have a 30-day return policy, and all rings are backed by a Lifetime Manufacturing Warranty covering manufacturing defects.
Is the shipping secure and discreet so the surprise isn't ruined?
Yes. All orders ship via insured express carrier (UPS) with a direct signature required on delivery. Package labels are unbranded and discreet, so your proposal surprise stays safe.
"A custom piece of fine jewelry is more than an object. It is a lasting archive of moments. We are committed to making your journey as seamless and memorable as the ring itself."
