Aquamarine: A Blue Variety of Beryl

Aquamarine is the blue to greenish-blue variety of beryl. It shares its mineral family with emerald while presenting a different color identity.

Its Mohs hardness is approximately 7.5 to 8. That describes scratch resistance, not an assurance that every item can be handled or cleaned in the same way.

Color is a starting point

A blue appearance does not identify an unknown stone as aquamarine. Other materials can resemble it, and photographs cannot provide a complete laboratory conclusion.

Read the actual material identification before relying on the product name.

Look at the individual stone

Compare the color and appearance under reasonable viewing conditions. Record dimensions alongside weight and consider the shape in the proposed jewelry design.

A large enlarged image may not explain how the stone will look in a finished setting. Ask to see the actual item in a useful context where possible.

Treatment statements deserve attention

If a seller makes a treatment claim, ask which information supports it. Read the report's scope and comments rather than treating silence in a product description as proof of an untreated stone.

For a question about a specific process, confirm whether the available examination can address it.

Separate origin from identity

The identification aquamarine does not establish a particular geographic source. If a country name is part of the sales description, check the basis of that statement separately.

Prepare for care and documentation

Share the report and known history with a jeweler before repair or resetting. Retain purchase documents and records of later work.

For an identification enquiry, provide the current material description, approximate size, mounting status, and the question you would like answered.
