Overview
Strong custom-setting program with transparent sourcing documentation on every stone.
Sterling & Vane positions itself as the transparent alternative to traditional engagement ring retailers, and on the documentation side, it largely delivers — every diamond over 0.3 carats ships with a full chain-of-custody record, not just a grading report.
The custom-setting process is genuinely consultative rather than a template picker: buyers get a live video session with a staff gemologist before committing. That quality comes at a cost in turnaround time, and buyers on a tight deadline should account for the 4-6 week production window.
Pros
- Full chain-of-custody documentation on every diamond
- In-house resizing within the first year, free of charge
- Live video appointments with a gemologist before purchase
Cons
- Custom settings can take 4-6 weeks to produce
- No physical showroom outside two US cities
