Diamonds are some of the most beautiful and valuable gems in the world. Their brilliant sparkle and timeless elegance make them a popular choice for engagement rings and other jewelry. However, diamonds can lose their luster over time if not properly cared for. Deep cleaning a diamond restores its shine and helps maintain its value. Here are some key questions and answers about deep cleaning diamonds:
Why does a diamond need deep cleaning?
There are a few reasons a diamond may need a thorough, deep cleaning:
- Build up of dirt, oil, lotions, and other contaminants – Diamonds attract oils and dirt from daily wear. These substances can cloud the diamond and make it appear dull.
- Loss of sparkle – Even if visibly clean, microscopic debris on a diamond can diminish its brilliance. Deep cleaning clears away these obstacles to light reflection.
- Prevent damage – Particles rubbing against a diamond can potentially cause microscopic scratches. Deep cleaning removes these particles.
- Pre-sale cleaning – Jewelers will often deep clean diamonds before sale to make them as dazzling as possible.
How often should you deep clean a diamond?
Most jewelry experts recommend deep cleaning diamonds every 6 months to 1 year to keep them looking their best. However, diamonds worn daily or that come in contact with lotions, perfumes, or dirt regularly may need more frequent deep cleanings every 3-6 months.
What’s the best way to deep clean a diamond at home?
Here are some effective options for deep cleaning diamonds at home:
Jewelry Cleaner Solution
- Soak diamond in a jewelry bath or bowl with warm water and jewelry cleaning solution for 5-10 minutes.
- Use soft-bristled brush or cloth to gently rub diamond while submerged to dislodge dirt and buildup.
- Rinse thoroughly and pat dry with soft lint-free cloth.
Mild Detergent
- Make a bowl of warm water mixed with a couple drops of mild dish detergent like Dawn.
- Soak diamond for 5-10 minutes, gently brushing with soft toothbrush.
- Rinse diamond very well to remove all soap residue.
Ammonia
- Mix 1-2 tablespoons of ammonia into a bowl of warm water.
- Soak diamond for 5-10 minutes, scrubbing gently with soft-bristled brush.
- Rinse thoroughly in plain water and pat dry.
What’s the best professional method?
Jewelers have access to powerful cleaning solutions and tools to deep clean even very dirty diamonds. Here are some common professional methods:
Steam Cleaning
- Diamond is placed in a steam cleaner filled with cleaning solution heated to around 212°F.
- The hot circulating solution dissolves and flushes away buildup.
- Ultrasonic vibration may be used to help dislodge particles.
Acid Bath
- A heated acid solution of hydrofluoric or nitric acid dissolves cloudy buildup on diamonds.
- Diamonds are rinsed thoroughly after acid bath cleaning.
- This method is especially effective at restoring brilliance.
Professional Jewelry Cleaner
- Sonic jewelry cleaners use ultrasonic waves and solutions to deep clean diamonds and jewelry.
- Powerful agitation lifts away microscopic debris.
- Safe for most diamond settings.
What solutions should you avoid?
Some common household cleaners are too harsh for diamonds and can cause damage. Avoid using:
- Bleach – Can discolor or erode diamonds.
- Vinegar – While mild, it can still corrode diamond over time.
- Chlorine – Pool chemicals like chlorine are very abrasive.
- Abrasive scrubbers – Scrub pads or brushes can scratch diamonds.
- Ultrasonic cleaner – Home units are not powerful enough and can loosen settings.
How can you check for damage after cleaning?
After deep cleaning a diamond at home, inspect it carefully using a 10x loupe or jewelers loupe for any damage like chips, cracks, or scratches. Look for any soapy residue or cleaning solution that may need further rinsing. Compare the diamond’s sparkle to before cleaning – it should appear brighter and more brilliant. If concerned about potential damage, take it to a jeweler for a professional inspection.
What are signs a diamond needs professional cleaning?
Consider taking a diamond ring or jewelry to a professional jeweler for deep cleaning if you notice any of the following:
- Extreme cloudiness or dark buildup
- Yellow or brownish discoloration
- Loss of significant sparkle even when visibly clean
- Dirt trapped under prongs or settings
- No improvement after multiple at-home deep cleanings
Jewelers have professional-grade cleaning solutions and ultrasonic/steam cleaners that may be needed for badly soiled diamonds or those with stubborn grime buildup.
How much does professional diamond cleaning cost?
On average, professional diamond cleaning costs $20 to $100 per ring or piece of jewelry depending on how extensive the cleaning process needs to be. More significant buildup requiring ultrasonic and acid cleaning will be at the higher end while a basic professional polish and cleaning may cost around $20.
Conclusion
Deep cleaning diamonds is essential for keeping them looking their sparkling best. While periodic at-home cleanings with mild detergent or jewelry cleaner can be effective, professional cleaning may be needed for diamonds that are very dirty or have lost significant brilliance. Be gentle when cleaning diamonds yourself and avoid harsh chemicals or abrasives. With proper care and occasional deep cleanings, your diamonds will maintain their beauty and value for many years to come.
