The value of platinum, which fluctuates based on the market conditions at any given time, is determined by the base price per gram.

Platinum is often used in jewelry, so some pieces may feature diamonds or other gemstones. In such cases, each gemstone is also evaluated and can add value to the overall appraisal.

When viewed as jewelry, the design quality and brand power also influence the appraisal. In cases of popular designs or items with high rarity value, the price may exceed the value of the platinum alone.

Platinum, known for its unique white shine, is widely used in jewelry and accessories. Often called "white gold," it is different from platinum, as white gold is an alloy made by mixing gold with other metals.
Platinum is a very rare metal (a "rare metal") with an estimated supply of only one-third of gold, and its annual extraction is just one-twentieth of gold. However, over 30% of the platinum mined is used as a catalyst in industrial products, making it an essential metal, even more so than gold.
Due to this, platinum is more susceptible to price fluctuations driven by global conditions and the economy, with its price volatility being larger than that of gold. Thus, careful and timely judgment is needed when selling platinum.
"Otakaraya" has extensive experience in purchasing platinum, staying updated on the latest market trends to offer high prices. In addition, dedicated and skilled appraisers conduct rigorous evaluations, ensuring the accurate identification of high-purity platinum, which translates into higher prices.
Platinum is often used in jewelry, so many items sitting unused at home may contain platinum. Why not have your items appraised at "Otakaraya"?
Even small quantities of platinum are in demand worldwide.

Platinum is a rarer and more precious metal than gold, but a significant portion is used for industrial purposes. It is highly susceptible to the impact of global conditions and the economy.
In the current unstable global situation, such as the effects of the virus, the price has gradually increased, with a larger increase compared to before. As platinum is a metal highly affected by global conditions, it is not surprising if the price fluctuates downward at any time.
Now, while the price is high, is the best time to sell.

Platinum comes in various purities, each with its own market value. While ingots are easy to value based on brand and weight, jewelry can be much harder to assess. At Otakaraya, our expert appraisers use their keen eyes and specialized measuring equipment to determine the true purity and value of your platinum—even if you have lost the certificates or warranty papers.
Beyond just the metal's weight, we add value based on the item’s craftsmanship. For high-end brands like Chanel or Harry Winston, we offer prices befitting their prestige. Even for one-of-a-kind original pieces, we provide premium payouts if the design is exceptional.
We also buy antique items and industrial platinum. No matter the condition, we evaluate every piece strictly and fairly. Even if other stores have turned you down, please consult us. You might be surprised to find that your items contain rare metals of significant value.
Appraisals are free, and inquiries are always welcome. Feel free to visit us just for a question or a quote!
