Moissanite is a gemstone known for its brilliance, fire, and durability, making it a popular choice for rings, earrings, necklaces, and pendants. Despite its resilience, Moissanite can develop a thin layer of oil over time, commonly referred to as an oil slick.
This layer forms from natural skin oils, lotions, perfumes, and environmental particles. The result is a gemstone that looks dull and lacks the characteristic sparkle for which Moissanite is prized. Removing the oil slick is essential for maintaining the gemstone’s reflective properties.
By understanding why it forms and using proper cleaning methods, Moissanite can regain its brilliance without risk of damage to the stone or setting.

Why Oil Slick Appears on Moissanite
Oils from Skin Contact
Moissanite frequently contacts the skin when worn as rings, earrings, or pendants. Skin naturally produces oils that transfer to the stone, accumulating in crevices, under prongs, and along chain links. This oil layer creates a semi-invisible film that prevents light from fully reflecting off the gemstone, diminishing its visual brilliance.
Residues from Products
Lotions, perfumes, and hair products also contribute to oil buildup on Moissanite. Even small amounts of these products can form a residue on the stone. Earrings and necklaces are particularly vulnerable because they come into contact with sprayed hair and scented products, which cling to the metal and stone.
Environmental Factors
Dust, cooking oils, and airborne particles further compound the oil slick. These environmental residues combine with natural skin oils, forming a film that is difficult to remove with a simple wipe. Areas like the underside of pendants or between chain links are prone to stubborn buildup, making careful cleaning essential.
Tools and Materials Needed for Cleaning Moissanite
Cleaning Solutions
Mild dish soap mixed with warm water is ideal for breaking down oil on Moissanite. Avoid harsh chemicals that can damage the stone or its metal setting. The solution should be gentle yet effective in loosening residues without compromising the gemstone.
Brushes
A soft-bristled toothbrush or jewellery brush is crucial for reaching tight spaces such as prongs, chains, and pendant settings. The bristles help lift oil from crevices without scratching the stone or surrounding metal.
Drying Cloths
Microfiber or lint-free cloths are necessary for drying and polishing Moissanite after cleaning. Proper drying prevents streaks and ensures no moisture remains that could leave a secondary film on the gemstone.
Optional Advanced Tools
Ultrasonic cleaners and steam cleaners are useful for removing deeply embedded oils. Ultrasonic cleaning works by vibrating the solution at high frequencies to dislodge oil from hard-to-reach areas, while steam cleaning uses high-temperature steam to dissolve and lift stubborn residues. These tools should be used carefully to avoid loosening delicate settings.
Step-by-Step Process to Remove Oil Slick from Moissanite
Step 1: Soak the jewellery
Start by preparing a warm water solution with a few drops of mild dish soap. Place the Moissanite jewellery in the solution and let it soak for 10 to 15 minutes. This soaking loosens oils and softens residues that cling to the surface and prongs. Soaking is especially important for jewellery with intricate settings, as oils can penetrate areas that are difficult to clean manually.
Step 2: Brush Moissanite Gently
Using a soft-bristled toothbrush, brush all surfaces of the Moissanite piece. Focus on areas where oil accumulates most, including under prongs, along chain links, and on the backs of pendants. Use small, circular motions to lift the oil without scratching the stone or spreading residue to other areas.
Step 3: Rinse Thoroughly
After brushing, rinse the Moissanite under lukewarm running water. Make sure all soap and loosened oil are removed completely. For necklaces and pendants, carefully rinse each chain link and clasp to ensure no oil remains. Thorough rinsing is crucial to prevent streaks and maintain the stone’s reflective properties.
Step 4: Dry and Polish
Dry the Moissanite immediately using a microfiber or lint-free cloth. Pat dry and polish gently, paying attention to crevices and prongs. Proper drying ensures no moisture remains that could create streaking or secondary film. The gemstone should now be visibly brighter and more reflective.
Advanced Cleaning Methods for Stubborn Oil Slick
Ultrasonic Cleaning
Ultrasonic cleaning can remove oil slick that remains after manual cleaning. The high-frequency vibrations dislodge oils trapped in prongs, chain links, and pendant settings. This method works well for Moissanite rings and earrings, particularly those with intricate details. Careful handling is important to avoid loosening delicate stones.
Steam Cleaning
Steam cleaning penetrates hidden areas with high-temperature steam, dissolving oil buildup. It is especially effective for Moissanite necklaces and pendants where chain links and clasps can trap residue. Steam cleaning is a non-abrasive way to restore the stone’s natural brilliance.
Specialized jewellery Solutions
For persistent oil slick, gemstone-safe cleaning solutions formulated for Moissanite can be used. Immerse the jewellery according to product instructions, brushing gently if needed. Rinse thoroughly afterward to remove any remaining solution and avoid a secondary film forming on the gemstone surface.
Tips to Make Cleaning Moissanite More Effective
-
Soak jewellery long enough to soften oils fully before brushing.
-
Focus brushing on hidden areas such as under prongs, inside chain links, and beneath pendants.
-
Use gentle circular motions to lift oil rather than spreading it.
-
Rinse thoroughly to remove all soap and loosened oil.
-
