The joy of a high jewelry collection is as much about discovering and wearing beautiful gemstones as it is about engaging with the history, culture, and exceptional craftsmanship that shaped these pieces.
We marvel at certain natural gemstones that, having been excavated for only a brief period in history, now exist in rare quantities. We imagine the stories behind one-of-a-kind high jewelry pieces created by special order for nobility—treasures that remain hidden from the market unless the owner releases them. Rare high jewelry pieces are works of art, expressing the beauty of fine natural stones, brought to life by artisans through meticulous and sophisticated designs. To appreciate these works is to understand the relentless pursuit of beauty, to feel the stirring artistry within great works of art.
Collectors will find the unique story behind each work. Perhaps we may discover that the piece belonged to an aristocrat, or it may have been commissioned for a celebrity’s wedding day. Worn on the body, jewelry is by nature intimate and serves as a palpable link connecting those who touch it. Knowing the history and origin of each piece adds depth to any collection.
The beauty of high jewelry endures for generations. To collect is to create a rich heritage full of special meaning and memories to be shared with family and loved ones and to live on into the future. From a practical perspective, high jewelry is a traditional store of wealth. Made of precious stones and metals, it retains value, is portable, and is easily converted to cash. Precious metals and gemstones are durable and, in many cases, appreciate over time, especially when crafted into bespoke or historically significant pieces.
High jewelry transcends its material worth, gaining value as art or through association with renowned designers and houses.
The pleasures of a well-curated jewelry collection will deepen as it matures over time.
They may be part of a lifestyle that brings deep satisfaction to their owners. I would be happy to assist you on this journey.

High jewelry advisors can play a pivotal role in guiding purchases of expensive jewelry or building a collection. While still a less common practice in Japan, many successful collectors around the world rely on jewelry and art advisors, tapping into their expertise and networks to ensure informed and satisfying acquisitions of high-value items.
1.
Assessing a Client's Needs
Advisors identify the client's designer and brand preferences, taking into account lifestyle, budget, and collection objectives (e.g., personal enjoyment, investment potential) before recommending what would be most appropriate.
2.
Make Recommendations
and Introductions
High jewelry advisors may draw upon experience and knowhow to propose rare and superior quality … rare and superior-quality jewelry from retail brands and auctions worldwide.
3.
Provide Auction
and Private Sale Support
Advisors are familiar with the intricacies of auctions and private sales, enabling them to support clients through a smooth process while securing the best prices for acquisitions.
The research and decision-making process for buying jewelry and building a collection is typically time-intensive. Advisors can significantly reduce that time and effort, steering clients away from counterfeit, overvalued, or otherwise risky items, thereby enabling them to purchase jewelry with greater confidence.
This provides a general idea of how the process works, but it is important to remember that the relationship between advisor and collector is highly personalized. The goal is not to focus on a single, one-time transaction but to develop a long-term partnership.
Important points to consider
when building a collection
1.
Establish a Style
Jewelry is often regarded as “wearable art,” so it’s best to collect pieces that reflect your taste and lifestyle. Focusing on a specific style, such as vintage, contemporary, or particular brands, will help you build a cohesive collection.
2.
Brand and/or Designer Selection
Pieces from renowned high jewelry brands, such as Harry Winston, Cartier, Van Cleef & Arpels, and Bulgari, tend to hold their value over time and may even appreciate, depending on the piece.
3.
Understanding Quality and Materials
High jewelry is crafted from premium-quality precious metals and gemstones. The origin of the stone is also a key factor in determining its rarity and value.
4.
Rarity and Exclusivity
The value of a collection often depends on the rarity and exclusivity of the jewelry. Limited production pieces and custom-made creations are typically the most valuable. Vintage jewelry from esteemed maisons, for instance, is highly prized for its handcrafted artistry, much of which cannot be replicated today.
5.
Network with Trusted Professionals
Building relationships with trusted advisors, jewelers, and auction houses is essential for discovering exceptional pieces. Expert guidance can provide historical context and insight, helping you identify jewelry of enduring value.

The Hong Kong-based company was founded in 2010 by Tzvika Janover and Elad Assor. They founded FORMS with the knowledge and wealth of experience they inherited from a family of renowned diamond cutters with over 100 years of history. Their vision is to craft rare and ancient natural precious gems with exquisite skill and technique to bring one-of-a-kind, original creations to jewelry lovers around the world.
Renowned for its elegance and aesthetic sophistication, FORMS emphasizes quality and integrity in every design. Under the guidance of founder and creative director Tzvika Janover, the house follows a collaborative approach to design. Each piece is a masterful balance of exceptional materials, artistry, and innovation, resulting in jewelry that is both bold and timeless.
FORMS jewelry sometimes uses themes and materials associated with Japan. For example, the use of shakudo (an alloy of copper and gold used in Japanese kimono buckles 100 years ago), earrings inspired by the sublime ink paintings of Hiroshi Senju, and designs influenced by Japanese fans. These are the special elements that resonate with Japanese collectors, and anyone who holds a piece of FORMS jewelry in their hands will notice the attention to detail and the pursuit of perfection.
Located in Hong Kong's vibrant business center, the FORMS atelier is where master craftsmen innovate on time-honored techniques to create precise and unique pieces. The company is renowned for producing fewer than 100 pieces each year, with some pieces taking up to a year to complete focusing on perfection over quantity. The finished products are also called “works of patience” within the company.

Having spent my early years in New York and London, I returned to Tokyo during high school and enrolled at Sacred Heart International School Tokyo, later graduating from International Christian University (ICU).
After earning a Graduate Diamond certification from the Gemological Institute of America (GIA) in New York, I joined Harry Winston. I spent eight years in the Tokyo office before transferring to the company’s headquarters on Fifth Avenue in New York, where I worked for seven years. During my time at Harry Winston, I gained cross-functional experience across departments, including sales, sales administration&analysis, and client services. Upon returning to Tokyo, I joined Sotheby’s as a jewelry representative. There, I handled some of the finest gemstones and high jewelry brands from various eras, assisting Japanese clients with consignments and purchases. Notably, I managed two significant collections from private Japanese collectors, achieving a sell-through rate of more than 95% for both.In 2022, I left Sotheby’s Tokyo to further deepen my understanding of jewelry. I began studying jewelry design to gain a more comprehensive perspective on the craft, exploring its artistic, technical, and historical dimensions.
I am bilingual in Japanese and English, communicating fluently in both languages. With a deep global network in the jewelry industry at my fingertips, I am poised to connect clients at the highest level and provide services tailored to their needs. To this end, I leverage my extensive global experience to help build jewelry collections of genuine value that can be passed on from generation to generation.
