Are your diamonds certified?
Yes. Every center diamond in a Blanchet & Co. ring is GIA certified, and the certificate ships with your ring.
Can I get my ring resized?
Yes — every ring includes one complimentary professional resizing within 60 days of purchase. See our Size Guide for how to measure at home.
What metal do you use?
All Blanchet & Co. rings are solid 18k white gold — never plated.
How long does shipping take?
Standard domestic shipping is 3–6 business days after a 3–5 business day processing window. See our Delivery page for full details and international timelines.
What's your returns policy?
We want you to be completely sure about your ring. Reach out through our Contact page within 14 days of delivery to start a return or exchange; the ring must be unworn and in its original packaging.
Is my payment information secure?
Yes. All payments are processed through Shopify's secure, PCI-compliant checkout — we never see or store your card details.
Do you offer engraving?
Reach out via our Contact page before ordering and we'll let you know what's possible for your chosen ring.
