The great thing about 14k and 18k gold jewelry is that the pieces do not tarnish quickly. The jewelry pieces can easily been taken care of!
For jewelry pieces made in 14k and 18k gold with diamonds, simply use warm water and mild soap to remove dirt and oils with a soft tooth brush. If you want your diamonds to shine, please don't be lazy!
For jewelry pieces made in 14k and 18k gold but with gemstones, please be careful when you clean because gemstones are not as hard as diamonds, which are the hardest metal on earth. Therefore, when you are using the same method in brushing them with the soft tooth brush, please be a little bit more gentle and don't be rough!
Remember, please do not wear the jewelry at swimming and please stay away from chemical materials (such as perfume, hairspray, soap, lotion, etc). Please be gentle with the pieces and avoid contact with hard objects as this they will scratch and dent the metal.
Certainly, using a soft polishing cloth to clean the metal part of the jewelry is always a great way to maintain the gold's luster and keeping the jewelry looking at its best.
