01 / THE GEM AT A GLANCE
What is Dravite?
Dravite is a sodium magnesium tourmaline with representative formula NaMg₃Al₆(Si₆O₁₈)(BO₃)₃(OH)₃(OH) and reported Mohs hardness 7–7.5. Typical appearance includes brown to amber glassy elongated tourmaline prisms with striated sides on pale matrix; documented colours include brown, dark amber, nearly black, yellow-brown. Forms during metamorphism or boron-rich hydrothermal alteration, particularly in magnesium-bearing rocks.

Typical appearance includes brown to amber glassy elongated tourmaline prisms with striated sides on pale matrix; documented colours include brown, dark amber, nearly black, yellow-brown. Forms during metamorphism or boron-rich hydrothermal alteration, particularly in magnesium-bearing rocks. Reported reference localities include Slovenia; Australia; Italy; Brazil. These are mineralogical occurrence areas, not independently verified provenance for a particular sale item. Dravite is a tourmaline species, not a synonym for every brown tourmaline; mixed compositions may require gemmological or mineral chemistry tests. Require a species label, actual specimen dimensions, photographs of the object being sold, and disclosure of stabilisation, repair or chemical treatment. The hard crystals can have sharp broken edges; avoid inhaling rock-polishing dust and verify treatments on any faceted gems. Soft brush and mild damp cloth for stable pieces, avoiding sudden heat changes and ultrasonic cleaning for cracked or included material. Suitable for some cut-gem jewellery with protective settings, but brittle crystal tips and fracture-filled gems need extra care. The illustrative image is not an authenticated mineral specimen or product photograph. The name refers to the Drava river region of historical mineral occurrences in Europe. Crystal habit, colour and apparent size can vary substantially with geological setting and sample preparation. A visually plausible rendering is not evidence of chemical composition, geographic origin or an available product. For significant purchases compare with an established mineral reference and request scientific confirmation where the species is uncertain. Do not use collector minerals in drinking-water infusions or assume the safety properties of another mineral with similar colour. When viewing a gallery image, distinguish an illustration from a photograph of the actual specimen. The commercial listing should disclose dimensions, weight, treatment, condition, origin evidence and specific safety restrictions for the item offered.

Before you choose a stone
Compare images taken in more than one lighting condition, ask for views of the actual item and check how the cut and setting change its appearance. A gemstone type is not a standard grade: each natural specimen has its own colour, inclusions and workmanship.
THE GEMHOOD BUYER'S FIELD NOTES
How to choose Dravite: three checks
- 01
Dravite is a tourmaline species, not a synonym for every brown tourmaline; mixed compositions may require gemmological or mineral chemistry tests.
- 02
Request current photos, scale, origin evidence, condition, repairs and treatment disclosure for the specific specimen.
The hard crystals can have sharp broken edges; avoid inhaling rock-polishing dust and verify treatments on any faceted gems.
Suitable for some cut-gem jewellery with protective settings, but brittle crystal tips and fracture-filled gems need extra care.
These notes describe typical gem material and trade practices. They do not independently grade or identify a specific item offered for sale.
03 / BUY WITH CONFIDENCE
Natural, laboratory-grown, treated or imitation?
Dravite is a tourmaline species, not a synonym for every brown tourmaline; mixed compositions may require gemmological or mineral chemistry tests. Require a species label, actual specimen dimensions, photographs of the object being sold, and disclosure of stabilisation, repair or chemical treatment.
These distinctions should be clear in the listing for any particular gem. Treatments are not automatically unacceptable, but an undisclosed treatment, vague mineral identity or unsupported origin claim prevents an informed purchase. Where material identity materially affects value, an independent gemological identification report may be worth considering.
A CLOSER LOOK
Composition, chemistry and reported hardness
Dravite is a sodium magnesium tourmaline with representative formula NaMg₃Al₆(Si₆O₁₈)(BO₃)₃(OH)₃(OH) and reported Mohs hardness 7–7.5. Typical appearance includes brown to amber glassy elongated tourmaline prisms with striated sides on pale matrix; documented colours include brown, dark amber, nearly black, yellow-brown. Forms during metamorphism or boron-rich hydrothermal alteration, particularly in magnesium-bearing rocks.
Idealised composition is written as NaMg₃Al₆(Si₆O₁₈)(BO₃)₃(OH)₃(OH); naturally occurring materials may contain substitutions and intergrowths. Mohs hardness 7–7.5 measures resistance to scratching rather than durability against fracture.

How to buy authentic and accurately labelled material
Dravite is a tourmaline species, not a synonym for every brown tourmaline; mixed compositions may require gemmological or mineral chemistry tests. Require a species label, actual specimen dimensions, photographs of the object being sold, and disclosure of stabilisation, repair or chemical treatment.
Ask for a photograph of the exact piece, not a reference-library illustration. Confirm whether the item is natural, treated, assembled, coated, repaired or only visually similar to this species.

Jewellery suitability, safe handling and storage
Suitable for some cut-gem jewellery with protective settings, but brittle crystal tips and fracture-filled gems need extra care. The illustrative image is not an authenticated mineral specimen or product photograph.
The hard crystals can have sharp broken edges; avoid inhaling rock-polishing dust and verify treatments on any faceted gems. Soft brush and mild damp cloth for stable pieces, avoiding sudden heat changes and ultrasonic cleaning for cracked or included material.

Care, display and long-term preservation
Soft brush and mild damp cloth for stable pieces, avoiding sudden heat changes and ultrasonic cleaning for cracked or included material.
Soft or cleavable species may be permanently damaged by household chemical cleaners, pressure, grinding or soaking. For powdery, fibrous or arsenate-bearing pieces seek conservative, closed-display handling.

What the GemHood illustration can—and cannot—show
This guide uses an original AI-generated concept illustration of Dravite based on reported colours and crystal morphology. It is not a certified specimen photograph, a geological assay or evidence of stock.
The linked mineral reference should be consulted alongside laboratory testing or documented locality information when precise identity matters.

05 / MAKE IT LAST
How to care for Dravite
The hard crystals can have sharp broken edges; avoid inhaling rock-polishing dust and verify treatments on any faceted gems. Soft brush and mild damp cloth for stable pieces, avoiding sudden heat changes and ultrasonic cleaning for cracked or included material.
One essential care distinction
Mohs hardness describes resistance to scratching, not resistance to breaking. Gemstones with cleavage, existing fractures, porous surfaces or fillings can need extra care regardless of their hardness number. If you do not know whether a piece has been treated, begin with the gentlest appropriate cleaning method.
06 / CULTURE & MEANING
History, heritage and symbolism
The name refers to the Drava river region of historical mineral occurrences in Europe.
Traditional meanings and spiritual associations are part of cultural storytelling. They are not evidence that a gemstone diagnoses, prevents or treats any medical condition.
