Natural Diamond Supply Crisis and the Shift to 'Ethical Consumption'. Middle East Situation and Ethical Trends Reshaping the Jewelry Industry Front Lines. (Kobe International Jewelry Fair 5/14- Held)

RX Japan LLC (Headquarters: Chuo-ku, Tokyo, Representative Executive Officer and President: Takeshi Tanaka) will hold the '30th Kobe International Jewelry Fair,' Western Japan's largest*1 jewelry exhibition, for three days from Thursday, May 14th to Saturday, May 16th, 2026, at the Kobe International Exhibition Hall.

Currently, the global jewelry industry is undergoing a historical turning point. With the continued instability of natural diamond distribution due to recent global situations, the jewelry supply chain demands greater certainty than ever before.

Amidst this, technological innovation has enabled the stable supply of large stones with brilliance comparable to natural diamonds, along with a shift in ethical values. As a result, 'lab-grown (synthetic) diamonds' are gaining significant global attention as a next-generation choice, particularly among younger generations.

This exhibition will bring together 'natural stones,' whose unchanging value is being re-recognized for their rarity, alongside 'synthetic diamonds (lab-grown diamonds)' and 'synthetic moissanite,' which are rapidly gaining global popularity. It will be an excellent opportunity to experience the forefront of the jewelry industry, where traditional beauty and new values coexist.

Global Situation Hits Directly: The Rarity and 'Universal Value' of Natural Diamonds

The recent global situation has also impacted major diamond processing centers and distribution hubs, leading to a global reorganization of supply chains. Under these circumstances, the rarity of natural diamonds as a 'limited resource' is being reconfirmed, and their value as an asset is once again drawing attention.

Furthermore, to add more trust to the rarity of natural diamonds, the establishment of 'traceability' is currently progressing. Utilizing the latest digital technology to clarify 'where the stone was born and what route it took to reach your hands' is becoming a new form of quality certification for modern natural stones.

At the venue, you can interview domestic buyers and wholesalers who offer the highest quality brilliance with assured peace of mind.

Towards a New Standard: The Forefront of the Rapidly Growing 'Synthetic (Lab-Grown)' Market

Amidst changing supply systems and values, the 'lab-grown diamond' market is expanding at an astonishing speed. While synthetic diamonds have a strong impression as industrial diamonds, in recent years, the jewelry market for 'sustainable and high-quality gemstones' has grown rapidly.

Background of Rapid Growth in the Synthetic (Lab-Grown) Market:

◆ From 'expensive natural' to 'ethically clean synthetic' Primarily among Gen Z and Millennials, the criteria for choosing gemstones are shifting from traditional rarity to a new evaluation axis that emphasizes the production process—'what background the stone has and how it came into their hands.'

◆ Overwhelming Cost Performance: While possessing the exact same chemical and physical properties as natural diamonds, lab-grown diamonds allow for maximum volume and brilliance even on a lower budget, despite recent price increases. As a 'smart choice,' they are becoming mainstream not only in fashion but also in bridal scenes.
