A diamond engagement ring is crafted to shine, yet everyday wear can gradually dull its brilliance. Natural oils from your skin, cosmetics and household products leave a film that softens the sparkle and hides the finer details of the diamond. With the right care, your ring maintains its radiance, preserving both its beauty and its symbolism.
This guide explains how to clean your diamond engagement ring safely and effectively, the methods to avoid, and the best habits to keep it looking immaculate. Whether your ring is worn daily or only on special occasions, a thoughtful cleaning routine will ensure it continues to sparkle as it should.
Identify Your Gemstone and Metal First
Before you begin, it helps to understand exactly what you are caring for.
If you are unsure what your engagement ring is made from, your jeweller’s documentation is the best place to start, as it will outline the gemstone and precious metal. Platinum and gold used in fine jewellery should be hallmarked on the inside of the band, giving a simple way to identify the metal. If the hallmark has faded or is difficult to read, reputable Hatton Garden jewellers can confirm the details for you. Understanding this helps you avoid damage and care for your ring correctly.
This guide focuses on rings crafted from platinum or 18ct gold that are set with a diamond. If your engagement ring falls outside of this, it is always best to speak with your jeweller for personalised guidance, as certain gemstones and metals can be softer or more sensitive to heat, chemicals or even mild cleaning solutions.
How To Clean Your Diamond Ring At Home
If your ring starts to look cloudy, feels greasy to the touch or lacks the crisp brilliance it had when you first admired the sparkle of Hatton Garden engagement rings on display, these are signs that a clean is due. Lotions, soaps and natural oils can build up quickly, softening the shine of even the finest diamond.
The most effective approach is gentle but consistent care. Diamonds do not need aggressive cleaning, but they do benefit from regular attention. Oils and residue settle gradually, so smaller cleans carried out often are far better than leaving your ring until it looks noticeably dull. A simple weekly routine is usually ideal, as it prevents build up from forming in the first place and keeps your diamond looking consistently bright and luminous.

Start By Preparing A Warm Cleaning Solution
Begin by removing your diamond engagement ring so you can clean it safely and thoroughly. Choose a clean mug or small bowl and fill it almost to the top with warm water. The warmth helps loosen the light film of oils, lotion and soap that naturally gathers around the stone during everyday wear. Add a small amount of mild washing up liquid such as Fairy, then give the water a gentle stir so the soap disperses evenly throughout. To prevent struggling to retrieve the ring later, place your engagement ring on a teaspoon before lowering it into the water. Resting it on the spoon allows you to lift it out easily and avoids any risk of the ring knocking against the sides of the mug.
Allow Your Ring Time to Soak
Platinum and gold diamond engagement rings are well suited to warm, soapy water, so you can leave them to soak without concern. Once your ring is in the solution, leave it for about fifteen minutes. This gives the water and mild soap time to soften any film that has built up through everyday wear, and will make the next stage of cleaning easier.
Use A Soft Toothbrush
A child’s toothbrush with soft bristles is ideal for refreshing a diamond ring. Take the ring out of the warm soapy water and brush gently around the stone for a few minutes. The warm solution will already have loosened most of the residue so the soft bristles can lift it away without any need to press or work the brush into tight areas. A light, consistent motion is enough to clean effectively.
Once you have finished brushing, place the ring back into the soapy solution for a final soak. Empty the bowl and replace it with clean warm water to let the last traces of bubbles disperse. Pat the ring dry with a soft cloth and your diamond should look noticeably brighter.
