I recently visited Sakura Hoseki and the experience was fantastic! I purchased the most beautiful 10ct tennis necklace while I was on holidays in Japan. The staff went above and beyond even accommodating my change of mind and personally delivering my new choice to my hotel. Their selection is stunning and the service is exceptional. Highly recommend this store for anyone seeking beautiful jewellery and top notch customer care.

Sakura Hoseki is truly the best place to buy jewelry! From the quality to the customer service, they genuinely care about their clients, both in person and overseas. I purchased a tennis bracelet for my wedding online, and the team addressed all my concerns right away. The bracelet is stunning the quality and sparkle really speak for themselves. I was initially worried about buying such a significant piece online, but the Sakura Hoseki team reassured me and delivered perfectly. They go above and beyond to ensure all questions and concerns are answered, which I really appreciate. It’s rare to find such a genuine honest and caring business like Sakura Hoseki. I’ve received countless compliments from family and friends, and I can’t wait to shop for more pieces. Thank you, Sakura Hoseki, for making my big day even more special!

Excellent customer service and product!! I purchased a 5 ct tennis bracelet and it is beautiful 😍. I appreciated the updates and fast responses on my shipment to Canada. I will definitely purchase more items and visit the store in Japan! Hope to see you soon and thank you very much again 😊

I purchased a ring for my partner (who lives in Japan) from here (Australia) a few months ago and the service from Sakura Hoseki was excellent. They respond to emails promptly and make sure everything is done meticulously to your satisfaction and when I asked for a certificate for their jewelry they happily provided. I would definitely recommend.

Ordered the 3ct tennis bracelet in white gold about a month ago (to Austria) and I am still absolutely in love. I wear the bracelet almost every day and it still looks like on day 1. Every aspect of the purchase was just positive. Very friendly and quick communication from support, fast delivery, no problems with customs, quality is great specially for this price. Already put other pieces on my xmas wishlist. 😁 Thank you. 💜

FAQs

We don't have a physical location in the United States; our headquarters are in Tokyo, Japan. However, if you're in Tokyo, you're welcome to visit our office by appointment. Inside our office, we maintain a substantial inventory that's not listed on our website, offering unique and exclusive items for in-person exploration. Please contact us to schedule a visit or for any further inquiries. Thank you for considering us for your jewelry needs.

On our website, if an item is in stock, we aim to ship it within 2-3 business days. For items not currently in stock, please allow up to 15 business days for restocking and processing. After placing your order, you will receive an email with the exact delivery date for your item, so you stay informed throughout the process. Thank you for your understanding and patience.

Our reasonable pricing is possible due to two main factors:

  1. In-House Manufacturing in Tokyo: All our jewelry is made in our own factory in Tokyo, allowing us to control costs and maintain high quality.
  2. B2B Pricing Model: We offer wholesale prices to the public by using a Business to Business (B2B) pricing approach, providing cost savings to individual customers similar to what businesses enjoy.

These factors result in lower prices, cost savings, and access to quality jewelry.
