Dear Colleagues and Gem Lovers,

Summer is flying by and your next Bangkok Gem Night is almost here.

Monday, 7 September | 18:00–21:00
Revo Bangkok (Silom)

Followed by the usual late dinner at Nadimos for anyone who wants to keep the evening going.

As always:

No entrance fee. No pre-booking. Just good vibes and a shared love for gems and jewelry.

Expect gem-infused cocktails & mocktails, lively conversation, and our signature charity auctions where 100% of proceeds are going to the kids over at HDF Mercy Centre in Klong Toey.

This is one of the two biggest nights of the year for our community. Come catch up with old friends, meet new ones, and support a cause that matters.

Questions? Reach out anytime to Billie, Gil, or me (Simon).

See you on the 7th.

Will this gem be “too dark” (appear closer to a black colour), when mounted in a yellow gold bezel setting?

My guess is Tanzania.

Fluoresence UV active neon glow golden yellow grossular-garnet. 12.6 cts.

Sparkling inclusions. Some another similar have very tyni black inclusions (suspect graphite).

A friend found this concretion with me and we're thinking about what to do with it. Cut it in two halves? Leave it as is? Or cut it into disks?

Personally I think two halves could be nice but I'm absolutely no expert

On TikTok, there’s been a discourse going around about an owner of a turquoise mine who is sending Bomb Party (an MLM company that specializes in surprise blind bag-like jewelry reveals) turquoise jewelry as they label their turquoise products as turquoise magnesite, and he’s speculating that there is no actual magnesite and that it’s just resin.

Anyway, many Bomb Party reps have argued over the existence of lab-grown turquoise, and while there has been a 2024 study of the preparation of synthetic turquoise pellets (https://doi.org/10.1590/PPJA9080), I haven’t seen anything about lab-grown turquoise.

Upon researching, I also came across this article by
Shelby Gems Factory: https://www.shelbygemfactory.com/unraveling-the-science-of-lab-grown-turquoise-unveiling-the-captivating-hues/

which describes the process of lab-grown turquoise. Since the source sells these turquoise, I was wondering about the validity of the process that they have laid out. Thank you!
