Purchased a 9.05 ct bi-colour tourmaline from Lisbon Gem Exchange and couldn’t be happier. The colour of the stone is stunning, the cut is excellent, and the stone has exceptional brilliance in natural light. Communication was professional and transparent throughout. A smooth, trustworthy experience. Highly recommended!
The 8.25 ct pink tourmaline I bought from Lisbon Gem Exchange is simply breathtaking. Loupe clean, with a rich, vibrant pink that went beyond all my expectations. Truly a gem of rare beauty!
NGL, I hesitated spending so much on a stone. But what I’ve seen after receiving their 12ct peach tourmaline? Pure brilliance, no funny business. Not heat-treated, color feels organic. Even my jeweler buddy was impressed. Plus, direct sourcing makes me feel it's ethical too. Big thumbs up.
Here’s the thing, as a hobbyist collector, finding untreated stones isn’t easy.
Clean lines, no junk inclusions.
Plus, I got it at a price that didn't make me cry.
Just recently, I got a 15ct bicolour tourmaline. The way colors blend is insane! You won’t believe this, but under sunlight, it shifts shades like magic. Definitely gonna add more of their stones in my lil' collection.
With this 4.80ct bicolor tourmaline, you can literally see nature’s touch. The color transition is so mesmerizing—it feels like holding a piece of Earth’s story. More than just a gem, it’s a glimpse into our planet’s history. 💎🙌
If I'm honest, I used to think these gems were all the same till I saw their peach-pink tourmaline in hand. This stone is stunning!
Delivery was smooth Appreciate the transparency they offer.
Honestly speaking, I thought photos always exaggerate. But when I unboxed my green tourmaline, the clarity had me shook. It’s exactly as described, maybe better.
Looking back now, I should've trusted them sooner. my latest oder? The 28ct bicolour tourmaline. The stone speaking for itself - raw charm, pure brilliance. packaging was sturdy, felt they actually cared. Thaanks for this piece of art!
What surprised me was how untouched and raw the gem felt..Great clarity, pure, straight-from-earth feel.
TY for keeping it real.as
I’ve been using regular commercial gems for a while. But OMG, their 17ct strong greentourmaline made me realize what real quality feels like. Loupe clean, as they stated on the website. The color pops like it’s alive. If I had to describe it earth’s magic, untouched.
Delivery was super fast
In my journey of learning gemstones, their Panjshir emerald became my first serious buy. If you ask me, quality matches the hype. Not overly polished, pure color.
Def keeping it as an investment.
My 11ct tourmaline arrived super clean, no nonsense, no weird treatments. Loved it.
One thing I noticed after buying their 10ct lagoon tourmaline: it photographs well, but in real life, it’s even richer. The gem felt like a fresh pick from the earth. No fake shine or suspicious polish. Delivery took a few days, but overall 10/10 experience.
