This article highlights the soaring investment appeal of pink diamonds following the closure of Australia’s Argyle mine, while also underscoring the significant security and management challenges that accompany such ultra-high-value assets.
According to reports, the stolen pink diamond was valued at an extremely high price of approximately 3.7 billion yen. Since the closure of the Argyle mine in Australia, its largest source, in 2020, production has plummeted. Due to its heightened rarity, market prices have continued to rise, attracting attention as an investment target.
However, this incident has also highlighted the reality that high-value gemstones are difficult to store and manage, carrying risks such as theft.
“Purchased long ago and never used,” “Inherited from parents, but its value is unknown”—such gemstones may be lying dormant in your home jewelry box. In recent years, it is not uncommon for gemstones that had low appraisal value at the time to now be worth unexpected amounts due to soaring market values.
The store employs appraisers with GIA (Gemological Institute of America) certification. Each piece of jewelry is carefully appraised based on internationally recognized standards and the latest market data.
It handles a wide range of items, from pink diamonds to colored diamonds, colorless diamonds, rubies, sapphires, emeralds and other colored stones, as well as gold/platinum products and brand jewelry. Appraisal and cancellation fees are completely free, so customers can feel at ease even just to verify the value.
Now is the perfect opportunity to reassess the value of jewelry lying dormant at home.
