Black Tourmaline Heart

Our crystals do not routinely come with independent laboratory certificates. We provide information on the material, reported origin and known treatments based on our sourcing records, examination and research.

For customers who require independent verification, testing can be arranged through a qualified external gemological laboratory where appropriate, at an additional cost.

We believe in transparent information rather than certificates that do not provide meaningful independent verification.

At OOAKSTONES, we carefully curate our collection and believe in transparent sourcing. Natural crystals may undergo treatments such as heating or dyeing, which we disclose when known. Please refer to each product's material and Known Treatment information for details.
