Hackmanite is a rare sulfur-rich variety of sodalite and a tenebrescent mineral, which means that it has the ability to change color when exposed to sunlight. This is a process that reverses when the light changes. This phenomenon is also referred to as reversible photochromism. Hackmanite gems are pale to deep violet when first mined, and fade to grayish or greenish-white once exposed to sunlight. However, hackmanite gems from Afghanistan and Myanmar do the opposite and usually change from colorless or creamy-white to pink-red or violet under sunlight.

The website is well organized and works fast forward and back. Plenty of filters. Each gem is described in detail and you receive the one pictured. Gem material info and sources available. I would like to see more specifics on sources besides country- at least region or state and in the US with Turquiose which mine. Thanks!

I was looking for ammolite for my husband. Other websites are not always clear about whether they have genuine ammolite or simulated ammolite. I have purchased from GemSelect before and trust that the stones are genuine. Finding the stones I want is easy, and I love all of the search filter options!

Excellent prices, excellent gemstones, easy to navigating, at the checkout, only a part of my cart was paid, then I get back to my chart, and the missing gemstones were there, so I pay it.At the end of the day, I did 2 consecutive purchases, paying 2 shippings. But even with that issue, I’m sure that worth it.Thanks!
