Sell Platinum Jewelry in NYC

Platinum is white, dense, and often unstamped in a way that leaves people assuming it's white gold or sterling silver. It isn't either, and it doesn't price like either. Platinum has its own spot market that moves independently of gold and silver, sometimes trading above gold, sometimes well below it.

Because the confusion runs in every direction, we test every white metal piece rather than going by looks or by what you were told when you bought it.

Genuine platinum is usually stamped PT950 or PT900 (95% or 90% pure), sometimes just PLAT or 950PT. The stamp is a starting point, not proof, since white gold and silver pieces get mismarked or misremembered constantly.

The more reliable tell is density. Platinum is roughly 60% denser than 14K gold and more than twice as dense as sterling silver, so a platinum ring feels distinctly heavier than a same-sized white gold ring of similar thickness. We confirm with proper testing rather than a hand-weigh, but the density difference is real and it's why platinum rings often surprise people with how solid they feel.

Platinum is hypoallergenic and holds a prong tightly without the metal fatiguing the way white gold can over years, which is why it's the default choice for engagement ring settings and wedding bands at a lot of jewelers. If you have an older band that's never been re-rhodium-plated and still looks white rather than yellowing, there's a decent chance it's platinum rather than white gold.

Platinum settings are also common on diamonds specifically, since the metal doesn't compete visually with a colorless stone the way yellow gold can.

Same basic formula as gold and silver: weight in grams, multiplied by purity, multiplied against the live platinum spot price at the time you come in. PT950 is 95% pure, PT900 is 90%, and that percentage is fixed even as the dollar figure moves with the market daily.

Stones set in a platinum piece are valued separately from the metal, same as with gold. A platinum engagement ring gets priced as platinum-plus-diamond, not as one number.

Platinum is soft enough to pick up surface scratches easily, which is normal wear and doesn't affect what we pay. A bent band, a setting missing its stone, a ring that's been resized more than once, none of it changes the platinum content.

The one thing that does matter is plating or coating over a base metal claiming to be platinum, which is rare but does exist. Testing catches it either way, so bring it in regardless of what you're unsure about.
