4 Ways to Tell if sunstone is Real

Sunstone is often imitated using materials such as Goldstone or Calcite. It is wise to buy from reputable retailers and, if feasible, request a certificate from a gem testing laboratory. Here are some handy tips to help you initially discern the authenticity of sunstone.

1. Check the Color

Real: Real Sunstone, often orange but also can be colors like colorless, red, pink, or yellow, gets its color from included plate-like minerals like copper, goethite, or hematite. Hold it to the light; real Sunstone typically displays a speckled color distribution.
Fake: Upon careful observation under light, you will notice that goldstone's color is very uniform.

2. Check Aventurescence Effect

Real: The glitter in real Sunstone is understated, distributed naturally and unevenly. In a single stone, you may find both large and small glitters with varying intensity. Some glitters shine on the surface, while others emit a subdued gleam from within the depth of the stone.
Fake: Goldstones made from glass exhibit a cluster of glitters that appear identical and well-proportioned.

3. Hardness Test

Real: Real Sunstone cannot be scratched by a knife.
Fake: Fake Sunstone made from orange calcite can be scratched by a knife.

4. Acid Test

Real: No visible reaction will happen when hydrochloric acid or white vinegar is dropped on real Sunstone.
Fake: Fakes made from calcite may exhibit fizzing or effervescence when exposed to hydrochloric acid or white vinegar.
