Unvault is a modern platform designed for discerning sellers who want a fair deal without the hassle of traditional pawn shops or auction sites. When you sell platinum online through us, you benefit from:
We offer clear, competitive pricing based on live market rates and the purity of your metal.
Our gemologists and metal specialists verify the purity of your items. Knowing the purity of your platinum (for example, markings like 850, 900, 950 or 999 indicate 85–99% purity) allows us to provide an accurate quote.
Ship your items with free, fully insured packaging. A trusted buyer should offer secure transportation and coverage, and we adhere to that standard.
Unvault is backed by customer reviews on trusted platforms.
How It Works
Use our online platinum calculator to get an approximate price for your platinum ring, bracelet, coin, or scrap. Simply enter the weight, purity, and any gemstones. Our algorithm references the latest platinum prices and is updated regularly. The estimate shows what your platinum could be worth in seconds.
Request our secure shipping kit. Place your items in the tamper‑proof package and drop it off at your nearest courier. Your shipment is insured up to the full estimated value, so you can confidently sell your platinum from anywhere.
After our experts inspect your items and verify their purity (checking for markings such as 900 or 950), we send you a final offer. We consider weight, purity, and market trends—platinum is used not only in jewelry but also in industrial applications, which supports its value.
Accept the offer, and we will process your payment. Decline, and we ship your items back at no cost.
What to Expect When Selling Platinum
Platinum can be sold by the ounce or gram, and what you typically receive can depend on purity, weight, and market demand. Rings branded by designers like Tiffany or Cartier can command a higher price, while unbranded pieces are valued primarily for their metal content. Before you sell platinum jewelry, check the current market price and get multiple quotes to ensure you’re receiving a fair offer.
Although platinum is rarer than gold, its resale value can be more volatile. That’s why it’s crucial to partner with an expert buyer who understands the market. Unvault’s pricing model accounts for these fluctuations so you always get a competitive offer.
Skip the time-consuming visits to jewelers or pawnshops. Our platform lets you sell platinum jewelry from home. Get an online quote, ship your items for free, and receive payment quickly.
We use live market data and professional analysis to make offers that reflect true market value. Traditional pawnshops may pay significantly less (often half the spot value), whereas online metal buyers like Unvault aim to maximize your payout.
Your jewelry is personal. Unvault treats every transaction with discretion and care. Our shipping process is insured and trackable.
