This solitaire style setting makes an elegant choice for your center diamond, with a unique concave shape to the top of the band. The highly polished metal reflects beautifully on this curved design. The edges of the band are flat and squared off, with the inside of the band rounded for a soft, comfortable feel on the finger. The band is the same width all the way around the finger. This design is a subtle variation of a classic solitaire and will complement the center diamond.
This setting is made of platinum, a beautiful and popular precious metal for diamond jewelry. This pure white metal is the ultimate complement to the clear brilliance of diamonds. Platinum is typically 90 to 95% pure platinum, with the remaining percentage being alloys of other platinum group metals such as iridium and ruthenium for surface strength. Platinum does not splinter or wear away easily, making it the most durable choice for everyday wear. It is valued for its extreme rarity and incredible luster. As a precious metal, platinum will naturally patina, or scratch lightly on the surface, but the original bright polished luster can be maintained through an occasional cleaning and polishing.
