About Platinum

Platinum jewelry is very rare; in fact, 30 times rarer than gold. Platinum’s naturally white sheen will not fade or change color, making it an ultimate symbol for true and eternal love. Platinum can accentuate the sparkle and brilliance of a diamond, and at the same time hypoallergenic. Therefore, it is an excellent choice for lifelong engagement and wedding rings.

Density And Durability

Platinum has very high density hence high weight. A ring of platinum would be around 50% heavier when compared to a ring of gold of the same volumn. Because platinum is a naturally white metal, re-plating is unnecessary. It does not easily tarnish, chip or wear down, meanwhile it can withstand high temperature and always hold its beauty.


The purity of platinum used in jewelry is 90% or 95% (Pt900 or Pt950), mixing only 5-10% of other alloys. Its purity makes it naturally hypoallergenic, ideal for those with sensitive skin issues.


The rarity, durability and density of platinum, in combination with its high demand, make platinum 50-70% more expensive than 18K Gold.


Simply soak platinum in a mild solution of warm soapy water, and then gently scrub with a soft-bristled brush.
To minimize scratches and other damage, store your platinum jewelry either in a cloth pouch or in a separate compartment in the jewelry box.
As time goes by, platinum may develop a subtle patina, or tarnish. Diamania would provide professional clean and polish service at cost.
