Is there any way to tell if my platinum ring is pure platinum? — Beth in Stillwater, OK
The two most common purities of platinum used in jewelry are:
Plat – 950 Plat is considered nearly pure platinum and usually contains 95% platinum and 5% iridium. It is quite expensive and typically the highest grade of platinum available for jewelry making.
IridPlat – This platinum is 90% pure platinum with 10% other metals mixed in…typically iridium. These rings can be marked with a hallmark of “.90 Plat” as well and therefore have a slightly lower melt value than their purer platinum counterparts.
Obviously pure platinum will yield higher returns, however at around $1,322.00/troy ounce, platinum alloyed with other materials can return a surprisingly high melt value.

If I have a diamond ring that has this “90plat” engraved on inside of the band , regardless if the diamonds are real or not if melted down about how much would it be worth?? Also if just selling the ring about how much could it be worth??
Hi Amber —
You are right to look at the diamond value and the platinum value separately if you are wanting the precious metal value. (If you are selling as a ring setting, the values are combined).
We would need to know the weight of the platinum band (without the diamond). We could pay about 70% of the platinum content that is recovered. Contact us here with more info about your ring: http://www.archenterprises.com/contact-us.html
Thanks!
I found a HA PT950 ring and inquiring if ring is real or fake. if real what is the value of ring should I expect to receive should I decide to sell it if no one claims it within 3 months
