The fineness of gold utilized to set a piece of jewellery plays an integral role in its durability. At Bee’s Diamonds, we use the purest forms of gold in our products, consisting of either 18K gold, platinum or titanium. All jewellery bear a mark indicating the fineness of gold content and a detailed invoice or receipt stating the content will be issued at collection or delivery.
18K Gold (White / Gold / Rose / Black) The standard of fineness for 18K Gold is 750. This refers to the gold content being 75% gold and 25% being other gold alloys, including palladium and silver. 18K Gold jewellery can appear in white (silvery), black, purple, blue or even rose-colours. It is most commonly seen in white gold because of its strength to withstand normal wear and tear due to its rhodium plating which is extremely hard and it minimizes the jewellery's vulnerability to scratches.
Platinum For customers who may have slight risk of skin allergies towards the gold alloys used in 18K gold, we recommend setting your diamond onto platinum which is a dense, malleable, ductile precious, gray-white transition metal. The majority of platinum jewellery is 95% pure platinum combined with 5% iridium, palladium, ruthenium or other alloys. Although platinum is hard in nature, it is also extremely ductile and malleable which is not recommended for setting jewellery with refined details or with a valuable center diamond. Platinum is also vulnerable to daily wear and tear and can be susceptible to scratches resulted from constant contacts with hard surfaces.
Titanium Titanium is increasingly becoming popular as a jewelry material due to its unique properties. It is hypoallergenic, lightweight and corrosion-resistant. It is also non-toxic to the human body. Titanium rings are therefore practical for those who regularly swim in ocean or chlorinated pools. However, titanium rings can have varying degrees of fatigue resistance and tensile strength. Titanium is comparable to steel in its resistance to sawing. The following table compares and summarizes the three major metals used in high jewellery:
