My favorite quality of platinum – and my customers agree – is the fantastic brightness it emits while brazing at 3000° Fahrenheit. Platinum’s high melting temperature means that much more fire is involved in the melting, annealing, and fabrication of a piece of platinum jewelry.
A platinum wedding ring is slightly more durable than gold, and has a heavier, more substantial feel. Platinum carries a certain level of cachet as well.
Platinum’s high density as compared with 18k gold means that more platinum is used in a wedding ring of the same size, so the volume of the wedding ring you design will have a significant impact on the total price.
I mostly use a popular Pt 950 alloy (95% platinum, 5% ruthenium) in wedding and engagement rings. I occasionally use a more malleable 900 Pt/Ir, depending on the design. While these two alloys are used in nearly all platinum jewelry made in the USA, there are other platinum alloys we can use to create our designs, including: Pt/Au (popular in Japan), Pt/Pd (popular in Thailand), and pure platinum.
The platinum we use in our shop is 99% recycled.
