The Mohs hardness scale measures a gemstone's resistance to scratching, ranging from 1 (softest) to 10 (hardest). This scale is vital for understanding how to handle and store your gemstone jewelry. Harder gemstones, such as diamonds, rubies, and sapphires, are more durable but can still chip under sharp impacts. Softer stones, such as pearls, turquoise, and opals, require extra care to avoid scratches and damage.

Wearing Tips: Amethyst, with a Mohs hardness of 7, is moderately durable but can scratch or chip with rough handling. Avoid wearing amethyst jewelry during outdoor activities or near heat sources, as prolonged sunlight can fade its vibrant purple color.

Treated Stone Considerations: Most amethysts are heat-treated to enhance their color. This treatment makes the stone more sensitive to high heat, so avoid exposing it to extreme temperatures during wear or cleaning.

Professional Cleaning: Professional jewelers can safely clean amethyst and restore its luster, especially in intricate or antique settings. They can also inspect the prongs and mounts to ensure the stone is secure.

Wearing Tips: Blue sapphire, with a Mohs hardness of 9, is one of the most durable gemstones, making it suitable for daily wear. However, it can still chip or fracture under sharp impacts, so avoid wearing sapphire jewelry during activities like heavy lifting or contact sports.

Storage Tips: Store blue sapphire jewelry in soft pouches or separate compartments within a jewelry box to prevent scratching other stones or being scratched by harder gemstones like diamonds.

Cleaning Tips: Clean sapphire jewelry with warm water, mild soap, and a soft brush. Rinse thoroughly to remove soap residue and dry with a lint-free cloth. Sapphire can generally tolerate ultrasonic cleaners unless it contains inclusions, which may weaken the stone.

Treated Stone Considerations: Most blue sapphires are heat-treated to improve their color and clarity. Some sapphires undergo diffusion treatments, which enhance surface color but are more prone to wear over time. Avoid harsh abrasives that may damage treated areas.

Professional Cleaning: Professional cleanings enhance the sapphire’s brilliance and ensure that treatments like diffusion remain intact. Jewelers can also polish small chips and secure any loose settings, preserving the gemstone’s longevity.

Wearing Tips: Citrine, with a Mohs hardness of 7, is durable but can still scratch or chip under heavy wear. Avoid wearing citrine jewelry during activities that might expose it to rough surfaces or sharp impacts. Its vibrant yellow and golden hues can fade with prolonged sunlight exposure, so remove it before spending extended time outdoors.

Storage Tips: Store citrine jewelry in a soft pouch or padded compartment, separate from harder gemstones to prevent scratches. Keep it away from direct sunlight and excessive heat to maintain its color.

Cleaning Tips: Clean citrine with warm soapy water and a soft brush. Gently scrub the surface, rinse thoroughly, and pat dry with a lint-free cloth. Avoid harsh chemicals or abrasive materials that can dull the stone’s polish.

Treated Stone Considerations: Most citrines are heat-treated to achieve their sunny hues. These treatments are stable, but exposure to high heat or chemicals can still affect the stone’s appearance. Handle carefully to preserve its brilliance.

Professional Cleaning: Professional cleanings help restore citrine’s sparkle and remove buildup in intricate settings. Jewelers can also check for loose prongs or other structural issues to ensure your piece remains secure.

Wearing Tips: Garnets, with a Mohs hardness of 6.5–7.5, are relatively durable but can scratch or chip under rough handling. Avoid wearing garnet jewelry during activities like gardening, sports, or house cleaning. Its surface can lose polish over time, so handle with care.

Storage Tips: Store garnets individually in soft-lined compartments or pouches to avoid scratches from contact with harder gemstones. Keep them in a dry, cool place away from direct sunlight to maintain their luster.

Treated Stone Considerations: Garnets are typically untreated, making them relatively low-maintenance. However, some rare varieties may be enhanced for color. Consult a jeweler for specific care instructions if your garnet has undergone treatment.

Professional Cleaning: Professional cleanings help maintain your garnet’s brilliance and polish. Jewelers can also inspect and tighten settings to ensure your jewelry remains in excellent condition.

Wearing Tips: Opals, with a Mohs hardness of 5.5–6.5, are soft and vulnerable to scratches, chips, and cracks. Avoid wearing opal jewelry during physical activities or in extreme temperature conditions, as sudden temperature changes can cause the stone to crack. Opals are also sensitive to dehydration, so wearing them in very dry environments should be limited.

Storage Tips: Store opals in a cushioned, slightly humid environment, such as a soft-lined box with a small container of water nearby to maintain moisture. Avoid direct sunlight and dry storage conditions, which can lead to cracking.

Cleaning Tips: Wipe opals gently with a damp, soft cloth. Avoid soaking opals or using ultrasonic and steam cleaners, as these can damage the stone’s delicate structure. If a deeper cleaning is needed, consult a professional.

Treated Stone Considerations: Some opals are treated with resins, waxes, or dyes to enhance their durability and color. These treatments require extra care, as harsh cleaning methods can strip coatings or damage the stone.

Professional Cleaning: Jewelers can safely clean opals without risking their sensitive structure or treatments. Professional inspections are also crucial to check for cracks, dehydration, or loose settings, preserving the opal’s vibrant play-of-color.

Wearing Tips: Peridot, with a Mohs hardness of 6.5–7, is durable but susceptible to scratches and chips from heavy impacts. Avoid wearing peridot jewelry during strenuous activities or in environments with sudden temperature changes, which can weaken the stone.
