Bonas Makes History with Inaugural Colored Gemstone Tender

In a groundbreaking move set to captivate the global luxury market, Bonas, a name synonymous with excellence and integrity in international diamond tenders, proudly announces its very first colored gemstone tender. This highly anticipated event will unfold in conjunction with two of Asia’s most prestigious industry gatherings: the February Bangkok Gems & Jewellery Fair (BGJF) and the March Hong Kong Jewellery & Gem Fair. This strategic initiative marks a significant expansion of Bonas’s renowned expertise, bringing unparalleled access to a curated selection of precious colored gemstones for discerning buyers worldwide.

A New Era for Bonas and Colored Gemstones

For decades, Bonas has been the trusted platform for the world’s most significant diamond transactions, earning a sterling reputation for transparency, efficiency, and the quality of goods offered. Leveraging this extensive experience and global network, Bonas is now extending its unique tender model to the vibrant world of colored gemstones. This inaugural tender is not merely an event; it represents a new benchmark for acquiring rare and exceptional colored gems, offering a secure and reliable channel for high-value transactions. Organized with invaluable support from the Asia Gem Center in Bangkok, this tender is meticulously designed to meet the exacting standards of the luxury jewelry sector.

Targeting the Elite: Jewelers, Manufacturers, and Brand Houses

This exclusive tender is specifically tailored to cater to the refined tastes and demanding requirements of leading jewellers, innovative jewellery manufacturers, established wholesalers, and prestigious brand houses. Bonas understands the critical need for unique, high-quality pieces that differentiate collections and capture the imagination of end-consumers. Participants will find an unparalleled opportunity to acquire truly special, one-off gemstones that promise to elevate their designs, enhance their inventory, and provide a competitive edge in a dynamic market. Whether seeking a centrepiece for a bespoke creation or a significant addition to an investment portfolio, this tender provides an exceptional avenue.

An Exquisite Collection: Approximately 500 Lots of Precious Colored Gems

The tender will feature an astounding array of approximately 500 meticulously selected lots of precious colored gemstones, each chosen for its exceptional beauty, rarity, and investment potential. The collection showcases an impressive range, encompassing both certified and uncertified stones, as well as heated and crucially, unheated specimens. The emphasis on “no heat” certification for many key pieces underscores the natural beauty and rarity of these gems, a feature highly sought after by connoisseurs and investors alike.

Highlights of the Collection: Rubies, Sapphires, Paraiba Tourmaline & More

Among the dazzling variety, several categories stand out as star attractions:

  • Rubies: Renowned as the “King of Gems,” the rubies offered include magnificent examples with highly coveted characteristics. Many boast “No Heat” certification, signifying their untouched natural state, which significantly enhances their value and appeal. Origins from esteemed sources such as Burma and Mozambique are featured, often accompanied by GRS and GIT certifications affirming their quality and origin. The term “pigeon blood,” referring to a vivid, intense red hue, is used to describe some of the most spectacular rubies in the collection, including cushion and oval cuts.
  • Sapphires: Representing the pinnacle of blue magnificence, the sapphires in this tender are equally breathtaking. Predominantly featuring highly prized “royal blue” hues, these sapphires often originate from the legendary mines of Burma. Like their ruby counterparts, many are offered with “No Heat” certification, verified by leading laboratories such as SSEF and GRS, ensuring their natural perfection. The collection includes substantial carat weights in elegant oval cuts, perfect for creating iconic pieces of jewellery.
  • Paraiba Tourmaline: A truly rare and mesmerizing gemstone, Paraiba Tourmaline is celebrated for its electrifying neon blue and green hues, attributed to the presence of copper. The tender features stunning examples from Mozambique, presented in captivating trilliant cuts, each certified to assure its authenticity and quality. These are among the most sought-after colored gemstones in the world, representing a significant acquisition opportunity.
  • Padparadscha Sapphire: A jewel of exquisite rarity, the Padparadscha Sapphire is distinguished by its unique and delicate pinkish-orange hue, reminiscent of a lotus flower at sunset. This tender proudly presents an extraordinary 23.74ct oval Padparadscha Sapphire from Sri Lanka, boasting “No Heat” certification. Such a large, unheated specimen of this specific color is exceptionally rare and highly valued by collectors and investors.
  • Other Fine Colored Gems: Beyond these prominent categories, the tender also encompasses a diverse selection of other fine colored gems, ensuring a broad appeal to various tastes and design requirements. Each stone has been carefully vetted to meet Bonas’s stringent quality standards, promising a collection of unmatched distinction.

Prospective buyers seeking detailed specifications, comprehensive grading reports, and high-resolution imagery for all goods in the tender can expect full information to be made available towards the end of January 2020.
