Frequently Asked Questions (FAQs)

Yes. We specialise exclusively in natural gemstones.

Unless clearly stated otherwise, every gemstone offered by Lustre Ceylon is a natural gemstone. If a gemstone has undergone any known treatment or enhancement, we will disclose this to the best of our knowledge in the product listing.

Many of our gemstones are accompanied by certificates issued by respected and reputable gemological laboratories.

Where a gemstone is sold without a certificate, this will be clearly stated in the listing. If you require certification before purchasing, please contact us and we’ll be happy to discuss the available options.

No.

Natural gemstones may be untreated or may have undergone treatments commonly accepted within the gemstone industry, such as heat treatment for sapphires.

We believe transparency is essential, so any known treatments will always be clearly disclosed.

Heat treatment is one of the most common enhancements used in coloured gemstones to improve colour or clarity.

An unheated ( or ‘no treatment’) gemstone has not undergone this treatment and is generally considered rarer.

If a gemstone is described as unheated, this information is provided to the best of our knowledge and supported by certification where available.

We stand behind our gemstone descriptions.

If a gemstone sold by Lustre Ceylon as untreated (for example, unheated) is later confirmed by a recognised gemological laboratory to have undergone undisclosed treatment, we will honour our commitment to provide a full refund.

Our goal is complete transparency and long-term trust with every customer.

Note: We may request a copy of the laboratory report and, where necessary, the gemstone to be returned before processing the refund.
