COMPLIMENTARY SHIPPING AUSTRALIA WIDE| GIFT WRAPPED
Jan Logan offers complimentary shipping and a 14 days change of mind policy on all orders worldwide.
All our metal merchants are certified with the Responsible Jewellery Council (RJC) as meeting ethical, human rights, social and environmental standards as established by the RJC's Certification System.
All of our diamond suppliers adhere to the Kimberley process, a commitment to remove conflict diamonds from the global supply chain.
Approximately 80% of the world's coloured gemstones come from small-scale producers where the mining of these stones is a cultural tradition. Subsequently over many decades, we have established a commitment from these companies that they operate in a way that is honourable and environmentally sustainable.
Our coloured gemstones are natural so there can be a slight variance in colour.
