[Available 9/26 at 10 PM] Hong Kong Sourcing Gacha (7 types including Tanzanite, Hauyne, Color-Change Sapphire, Bekily Blue Garnet, etc.) 1 stone (plus 1 Rainbow Obsidian)

Introducing our Hong Kong Gem Gacha, featuring a collection of gems freshly sourced from Hong Kong.

This time, we have curated a lineup of 6 unique types of gems, hand-picked and purchased by the lot during our trip to Hong Kong in September 2026.

・Afghan Hauyne
While some inclusions are present, we have carefully selected stones with exceptionally vivid blue color and strong neon brilliance characteristic of Hauyne.

・Tanzanian Tanzanite
These stones have a significant presence at approximately 0.9ct. Although some minor inclusions may be visible, we have chosen pieces that showcase the beautiful blue-violet color typical of Tanzanite.

・Pakistani Jeremejevite
Known as a rare gemstone, Jeremejevite is highly prized. Despite their small size, these stones are exceptionally transparent and have been selected for their clarity, which makes finding inclusions difficult even with a loupe.

・Tanzanian Color-Change/Bicolor Sapphire
We have selected stones with lovely color profiles, including color-change varieties that shift hues depending on the light source, and bicolor types that display multiple shades within a single stone.

・Zambian Canary Tourmaline
These tourmalines feature attractive bright yellow to yellow-green hues. We have hand-picked the most vibrant stones with the strongest neon glow.

・Madagascan Bekily Blue Garnet
Known for being mined in the Bekily region of Madagascar, these garnets are famous for their color-changing properties. We have selected specimens with high clarity.

・Cambodian Ratanakiri Blue Zircon
Ratanakiri, in northeastern Cambodia, is renowned as a source of beautiful Blue Zircon. Zircon has a high refractive index and strong dispersion, making it a gemstone that sparkles like a diamond. We have selected stones with vibrant blue hues and exceptional transparency.

You are guaranteed to receive one of the seven types shown in the photos. Sizes vary by stone, so please refer to the photos taken with a ruler to check the dimensions. Enjoy the surprise of seeing which gem arrives!

Furthermore, with every stone purchased, you will receive one Mexican Rainbow Obsidian as a gift.

Rainbow Obsidian is a type of natural glass formed by volcanic activity. While it may look like a dark stone at first glance, it can reveal rainbow-like sheens of green, purple, and other colors when held to the light. It is a fascinating natural stone that changes its appearance depending on the viewing angle and how the light hits it.

We spent time in Hong Kong personally examining many gemstones to select those that best showcase the unique charms of each variety, from color and transparency to neon glow and color-change effects. Enjoy this exclusive Hong Kong-sourced lineup with our mystery gacha.
