    Common Treatments

    Aquamarine often undergoes heat treatment to enhance its blue tones by removing greenish hues. This is a standard practice in the gem world and doesn’t affect its durability or value.

    Durability Considerations

    Aquamarine is a hardy gem, but it's not invincible. While it can handle a little bit of heat, prolonged exposure to higher temperatures might cause its lovely blue hues to shift, so be careful when polishing a piece after the stone has been set. It doesn’t have cleavage, so no worries about it splitting in half, but watch out for chips along natural fractures—it’s a bit like a sturdy teacup: great for everyday use, but don’t go knocking it about.

    Jeweller's Setting Tips

    This gem loves a good protective setting—think bezels or recessed designs that cradle it gently. Casting it in place isn't the best idea, as aquamarine wouldn't survive the temperatures needed.

    Care Instructions

    To keep aquamarine sparkling, a little soap, warm water, and a soft brush works wonders. Avoid ultrasonic cleaners and steamers; they’re usually a bit too intense for this ocean-inspired beauty. Regular cleaning and mindful handling will ensure it stays looking its best for years to come.

    Aesthetic & Design Insights

    Aquamarine shines brightest in earrings, pendants, and statement rings. It’s perfect for adding a pop of serene blue to your designs, especially when paired with white metals like platinum, white gold or sterling silver. Want to really make it sing? Match it with diamonds or pearls for an elegant, timeless combo. Just be mindful of everyday wear if using it in rings—those edges will need a bit of extra protection.

    Market & Ethical Notes

    When it comes to value, deeper blues steal the show, especially when paired with excellent clarity. And the good news? Ethical sourcing is common, so you can easily find aquamarines with traceable origins that align with sustainable practices.

    Symbolic & Spiritual Meanings

    Legend has it that aquamarine was the treasure of mermaids, gifted to sailors as a talisman of protection. Known as the "stone of courage," it’s believed to soothe stress, enhance clarity, and inspire fearless communication. Whether or not you buy into the lore, there’s no denying that wearing one does feels a bit like you're carrying a piece of the ocean—tranquil, refreshing, and utterly serene.
