@salt_shack_geology: Spot the fake - Aquamarine Please be careful buying crystals online everyone. We get sent things like this all the time. Here are a few more tips: Colour Consistency: Genuine aquamarine typically has a pale blue or greenish-blue hue. Be cautious if you encounter aquamarine that appears too vibrant or intense in colour, as it might be a fake. Check for Flaws: Examine the gemstone for natural flaws or inclusions. Real aquamarine often contains small, internal imperfections, while fakes may be too flawless. Hardness Test: Aquamarine is relatively hard, scoring 7.5-8 on the Mohs scale. If you can easily scratch the gem, it might be a counterfeit. Transparency: Genuine aquamarine is transparent to translucent. If the stone is completely opaque, it could be a fake. Price and Source: Unrealistically low prices or aquamarine from dubious sources should raise suspicion. Authenticate the origin and price before making a purchase. Heat Treatment: Many aquamarines are heat-treated to enhance their colour. Ask the seller about any treatments the gemstone may have undergone. Lack of Lab Certification: Reputable gemstones often come with lab certification to verify their authenticity. Ask for certification when in doubt. Weight and Size: Be cautious if the gemstone appears significantly heavier or larger than typical aquamarines of the same carat weight. This could indicate a synthetic or fake stone. Observe Refraction: Genuine aquamarine has a moderate refractive index. You can test this by observing how light bends when it passes through the gemstone. Consult an Expert: When in doubt, seek the opinion of a certified gemologist or a reputable jeweller who can help you determine the authenticity of the aquamarine. #fakecrystals #crystaltok #aquamarine #saltshack #LearnOnTikTok
