Frequently Asked Questions
Is this a real diamond? Does it come with a certificate?
Yes. Lab-grown diamonds are real diamonds, with the same chemistry, hardness and sparkle as mined diamonds. Every solitaire lab-grown diamond comes with an IGI certificate and a unique laser inscription on the diamond’s girdle that matches its certificate.
When will my order arrive?
Each piece is handmade to order: 10–12 business days to make and 5–7 business days to deliver by express courier, an estimated 2–3 weeks from production to your door. You’ll receive a tracking number as soon as it ships.
Will I have to pay customs duties or taxes?
No. Shipping, insurance, import duties and taxes are all included in the price you see. Nothing more to pay on delivery.
What if it doesn’t fit, or I change my mind?
Please check your ring size carefully with our ring size guide and double-check it before ordering. If a ring doesn’t fit, email us at hello@gilibili.com: we can arrange a resize in some locations, or guide you to have it resized by a local jeweler.
If you change your mind, you can return an unworn piece within 30 days: email us within 14 days of delivery. See our Returns Policy for details.
What metal is it made of?
Every piece is made in solid 14K or 18K gold, or 925 sterling silver — never plated. Gold won’t tarnish; sterling silver can darken slightly over time and is easily restored with a polishing cloth. The diamond won’t scratch, chip or cloud with everyday wear.
