Platinum – For a Beautiful, Durable Engagement Ring

Platinum has quickly been established as the modern metal of choice for engagement rings. Platinum has many special qualities that make it ideal for this special ring:

Beauty.  Platinum is a beautiful and naturally white metal that will not affect the appearance of your diamond by casting its own colour on the jewel.

Rarity. This material is rare and precious and will show your loved one how highly you value her.

Durability. This metal is durable and will not tarnish with age so your platinum engagement ring will retain its beauty for a lifetime.

Only platinum with a high purity and great strength is used in the PORTFOLIO of Fine Diamonds collection. This ensures we can make beautiful, lasting diamond rings in a wide variety of styles and shapes. You will find the perfect platinum engagement ring for you within our range.
