Is My Bracelet Sodalite or Amethyst, and How Can I Tell Them Apart?
Sodalite or amethyst? Learn the limits of colour and reference measurements, why home scratch tests can damage beads, and what to ask a gemologist.
Colour alone does not establish whether a bracelet is sodalite or amethyst. Ask a qualified gemologist to assess the bead against references for both materials; the amethyst reference values below are comparison data, not a unique identification test.

What is the main rule for identifying the beads?
Treat a resemblance or a matching value as a clue, not a complete identification. A bracelet photograph does not provide the measurements needed to assess its material.
This guide has reference data for amethyst. Those data alone cannot establish that a bead is sodalite or rule out every other material. Ask a qualified gemologist what further observations and references are needed for the actual bead.
Which amethyst reference values are available?
The International Gem Society amethyst reference lists a specific gravity of 2.651, a refractive index of 1.544–1.553 and a Mohs hardness of 7. These values describe reference properties of amethyst.
A reading consistent with these values is not, by itself, proof that a bracelet bead is amethyst. This guide does not provide a sodalite reference range, so it cannot turn those figures into a complete identification comparison.
Why should you avoid scratch and heat tests at home?
GIA's amethyst care guidance describes Mohs hardness as resistance to scratching and rates amethyst at 7. Hardness does not measure resistance to breakage. GIA also notes that quartz occurs in ordinary sand and dust. Scratches therefore do not settle whether a bead is genuine amethyst.
GIA warns that sudden temperature changes can fracture amethyst. Avoid flame and hot-pin tests on a bracelet you want to keep intact.
Can the colour of amethyst change?
GIA states that sustained intense light may fade the colour of some amethyst specimens. A bead's current shade is therefore an incomplete basis for identifying it.
Colour, a seller's description and a mineral reference value answer different questions. A professional assessment needs to consider the actual bead rather than assuming that one clue establishes its identity.
What can a product listing tell you?
A listing states what the seller offers; it is separate from testing an unknown bead. Dusk & Relic lists amethyst in Lilac Hour (13mm, $115) and Amethyst Tide (8mm, $105). Those listed specifications do not identify a bracelet bought elsewhere.
For a mixed-material example, Happiness Is (11mm, $95) includes several stones. The listing for one piece should not be used as an identification reference for another.
How should confirmed amethyst be cleaned?
GIA recommends warm soapy water for amethyst and advises against steam cleaning and heat. That guidance covers the gem, not every cord, adhesive or other component in a bracelet.
Bolivian Dusk (11.5mm, $165) combines amethyst and freshwater pearl. Check the care guidance for every material before cleaning a mixed-material piece.
FAQ
Can a photograph confirm that my bracelet is sodalite?
This guide cannot identify your bracelet from its colour. Ask a qualified gemologist to assess the actual beads; the amethyst reference data here do not establish sodalite identity.
Does matching a reference value prove that a bead is amethyst?
No. A value consistent with amethyst is a clue for assessment, not a unique identification result.
Does a scratched bead rule out amethyst?
No. GIA notes that quartz occurs in ordinary sand and dust. Surface wear alone does not settle the material identity.
Is a flame test suitable for an amethyst bracelet?
Avoid it. GIA warns that sudden temperature changes can fracture amethyst.
