Visit a Specialized Purchase Store Otakaraya to Sell Your Gemstones / Jewellery
Do you have unused gemstones or jewelry lying dormant? It's a waste to leave them unused just because of reasons like "old design" or "scratches." At "Otakaraya," we offer high-price purchases even for broken jewelry or old designs. We purchase not only diamonds but also color stones like sapphires, rubies, and emeralds. You can also bring in loose stones (gems only), and our professional appraisers will assess their quality and grade. Whether it's a ring that no longer fits, a necklace that's broken, or jewelry that has become dirty over time, we can still make an offer. We will provide an estimate after evaluating the items, so feel free to bring them in. At "Otakaraya," we have specialists in diamond and gemstone purchasing, including a GIA G.G. certified appraiser, so you can bring your items in with confidence. If you want to sell your gemstones or jewelry for the best price, please visit us by all means.
Points for Gemstone and Jewelry Purchase
Gemstones are a limited resource created by nature, and their prices are highly influenced not only by their size and grade but also by factors such as market supply and circulation. As a result, some dealers may try to offer low purchase prices in order to maximize their profits. However, at Otarakaya, we have established stable sales channels, enabling us to buy high and sell high. Even if you were unsatisfied with other dealers' appraisals, we are confident that we can offer you a price that meets your expectations.

Frequently Asked Questions
about Gemstones / Jewellery Purchase
When is the best time to sell diamonds?
The best time to sell diamonds can vary. Sometimes, the right opportunity arises quickly, while at other times, holding onto them for a longer period can increase their value. It is difficult to pinpoint a universally ideal time. If you plan to keep your diamonds for a longer duration before selling, it is essential to store them properly. We recommend using appropriate storage methods and performing regular maintenance to preserve their condition.
Can I sell diamonds without a certificate?
Yes, you can. Our appraisers will evaluate the diamond 4Cs (Carat, Color, Clarity, and Cut) and provide you with a purchase price.
Does the design affect the purchase price?
For gemstone purchases, the grade of the diamond itself is crucial. Even with an older design, Otakaraya ensures a high-value purchase, so you can rest assured.
Does the shape of the diamond affect the purchase price?
Yes, the purchase price varies by shape. The "round brilliant cut" is the most highly valued cut for diamonds. The purchase price also changes depending on the diamond's grade, so feel free to take advantage of our free appraisal service.
Do specialty gemstone purchase shops offer higher prices?
At Otakaraya, we handle a wide range of items, including diamonds, gemstones, jewelry, gold, precious metals, branded items, and watches. This extensive sales network allows us to avoid holding excess inventory, enabling us to offer the highest possible prices for your items.
Can melee diamonds (pavé diamonds) be purchased?
Yes, they can be purchased. Jewelry adorned with melee diamonds (pavé diamonds) may receive a higher appraisal value. However, loose stones may not be eligible for purchase.
