She further believed that each individual stone had a divine blessing from God. This is what she had to say about sapphire:

“who is full and would like to be clever, should, in a sober stare, frequently lick with the tongue on a sapphire, because the gemstone’s warmth and power, combined with the saliva’s moisture, will expel the harmful juices that affect the intellect. Thus, the man will attain good intellect”.

4Caring for YouR Star Sapphire

Because of the Blue Star Sapphire hardness and durability they are considered one of the toughest gemstones on earth. It is only slightly softer than diamonds, but lacks cleavage which makes it resistant to damage. Fracture-filled stones are not as durable as untreated Blue Star Sapphire. Re-cutting or re-polishing a star sapphire that has been fracture-filled is not recommended. Even beryllium diffused gemstones will require care depending on the quality of the diffusing job. Star sapphires can be brittle stones, and thus, appropriate care should be taken during any re-cutting and during setting.

Clean you star sapphire with warm soapy water and a soft cloth. Avoid ultrasonic cleaners and steamers, especially if you have a fracture-filled stone. The vibrations and heat can damage the gem.

Remove any sat sapphire jewelry before exercising and cleaning to avoid getting it in contact with any harsh chemicals. Store them separately or covered to avoid scratches from other gemstones. We recommend wrapping them in a soft cloth and storing them in a fabric-lined box.
