What Platinum Jewelry Grades Do We Accept?
North Bay Rare Coin & Jewelry accepts platinum jewelry across all common purity grades. Platinum purity is measured in parts per thousand and may appear stamped on your piece as Pt950, Pt900, or Pt850.
- Pt950 or 950: 95% pure platinum, the most common standard for fine jewelry in the U.S. and abroad.
- Pt900 or 900: 90% pure platinum, often found in vintage or European-crafted pieces.
- Pt850 or 850: 85% pure platinum, the lower end of commonly accepted jewelry-grade platinum.
- PLAT or Platinum (no number): In the U.S., this stamp typically indicates at least 95% purity.
- Pt999: Investment-grade or bullion platinum, the purest form.
If you are unsure what markings appear on your piece, or if you have an antique item with no visible stamp, that is not a problem. North Bay Rare Coin & Jewelry has the expertise to assess unmarked or estate platinum items as well.
How Is Jewelry Valued by a Platinum Jewelry Buyer?
Platinum is denser and heavier than gold, which means even a modest-looking ring can carry significant metal content. Beyond weight and purity, North Bay Rare Coin & Jewelry also evaluates designer origin, condition, and collectibility.
Designer Brands and Collectible Value
Pieces by luxury brands such as Tiffany & Co., Cartier, and Bvlgari can carry meaningful premiums above raw metal value. Estate and vintage platinum jewelry may also be assessed for historical significance. The team applies market knowledge built over decades to ensure your valuation reflects what your platinum is genuinely worth, not just spot price.
