Mohs' Hardness score is based on a 10 point scale where 10 is the most resistant, like a diamond, and 1 is easily scratched, such as Talc. Aquamarine gets a score of 7.5-8, meaning that it is quite scratch resistant and therefore suitable as a component of jewelry. Aquamarine gemstones should be regularly cleaned by a professional or with a soft rag and mild soap and water or an ultra-sonic cleaner. Avoid solvents and harsh chemicals when cleaning your handcrafted jewelry as exposure to these elements can damage semi-precious and precious gemstones and pearls. Learn more about all semi-precious gemstones, including amethyst, apatite, black onyx, blue topaz, carnelian, chalcedony, citrine, coral, garnet, white topaz, crystal, diamond, emerald, iolite, jade, Labradorite, moonstone, pearl, peridot, prehnite, rose quarz, ruby, sapphire, smokey topaz, tanzanite, tourmaline and tourquoise when you check out this gemstone chart: www.dashaboutique.com/gemstone chart.html.
