When and where is Jewellery & Gem ASIA Hong Kong 2026?

Jewellery & Gem ASIA Hong Kong runs 18–21 June 2026 at the Hong Kong Convention and Exhibition Centre (HKCEC).

Where is Caram's booth at the show?

You'll find Caram in the gemstone halls at Booth 3E-323, Hall 3.

What is Caram showing at JGA 2026?

A curated selection of rare colored gemstones — emeralds, sapphires, and rubies — including matched parcels, calibrated layouts, and stones for bespoke and production work.

Can Caram prepare a selection before my visit?

Yes. Share your sourcing brief and Caram will have options ready at the booth. Appointments are recommended; walk-ins are welcome as the schedule allows.

How long does a bespoke jewelry commission take at Caram?

A typical Caram bespoke commission takes 8 to 14 weeks from first consultation to unveiling, depending on the gemstone selection process and design complexity.

Can I redesign an inherited piece into a bespoke jewel?

Yes. Many bespoke commissions begin with an inherited jewel. Caram assesses the existing stones, proposes a new design, and either resets or recuts the piece as required.

Do I need to choose a gemstone before starting a bespoke design?

Not always, though it usually shortens the process. The character of the gem often shapes the design. If no stone is yet in mind, Caram guides selection during the first consultation.

The feature — "Are Tanzania's Mahenge Pink Spinels Finally Reaching America's Jewelers?" — reports on a notable uptick in fine Mahenge spinel supply appearing at Tucson's GJX show and in the broader trade. Rahul is quoted alongside American Gemological Laboratories president Christopher Smith and Bangkok-based dealer Lambert Vissot as one of three primary industry sources on the shifting supply picture.

"I accelerated my buying. I just noticed there's a lot more nicer material available now." — Rahul Jain, JCK, on the Bangkok shows in late 2025

Rahul's contribution to the piece focuses on why the recent supply appears to be fresh production rather than old stock working its way through secondary markets:

"If it was a secondary supply, you'd see it from dealers in other cities like New York."

Mahenge, in southern Tanzania, is widely regarded as the source of the world's most saturated pink spinels. Fresh material in larger sizes had been assumed scarce since the 2007 discovery of the region's most famous pocket. The JCK piece explores whether the current supply represents a new deposit, improved mining, or long-held stock reaching the market — and what that means for American jewellers.
