Top 10 Gemstones with the Most Beautiful Rough Crystals

Metal_Treasure
Some gemstones look beautiful even before the jeweler's touch. Not all gemstones look great before that. But some do.

The Top Ten

1 Amethyst Amethyst

Amethyst crystals look like a medieval village on a hill, with a nice skyline, where buildings have pointy Gothic roofs, etc.
When all crystals in the bunch are big, amethyst crystals look like skyscrapers.
Amethyst crystals can also look like a mountain with many peaks. - Metal_Treasure

2 Chrysoberyl Chrysoberyl

It's the 3rd hardest gemstone after diamond and sapphire, with hardness at 8.5 out of 10. Besides, this gem can form a "cat's eye", a desired optical effect, and chrysoberyl does it best.
The image shows a rough chrysoberyl crystal, not touched by a jeweler. I would even say "Don't touch it. Don't cut it". It's already beautiful.
The specimen is from Brazil. - Metal_Treasure

3 Trapiche Emerald Trapiche Emerald

Incredible combination of 2 colors forming a captivating 6-ray pattern! They are clearly visible in the rough crystals of Trapiche Emerald.
Crystals of the "ordinary" green emerald (without black carbon inclusions) look like the crystals of aquamarine and red beryl (see them below) but are green. Color is the only difference between these 3 gems because they are from the same gem family - beryl. - Metal_Treasure

Ahhh! A gemstone that has an astonishing 6 ray pattern by my favorite color appealing to my autistic eye! Yet it look like that the pattern is pulsating and yes very appealing indeed and my own personal emblem- Kevinsidis

4 Elbaite Elbaite
5 Aquamarine Aquamarine

That’s so beautiful!

Perfect 6-sided crystals (all beryls have a hexagonal crystal system).
Unlike amethyst, aquamarine crystals aren't pointy (same for emerald and Red Beryl / Bixbite) - Metal_Treasure

6 Red Beryl (Bixbite) Red Beryl (Bixbite)

Great color and flawless hexagonal crystals (with 6 sides). Red beryl crystals usually occur in groups, like aquamarine. - Metal_Treasure

7 Watermelon Tourmaline Watermelon Tourmaline
8 Rutilated Quartz Rutilated Quartz

Some of its crystals look like a gorgeous fireworks display on New Year's Eve! Fireworks inside the gem! - Metal_Treasure

9 Chambersite Chambersite

Why is this not higher on this list?

10 Purple Taaffeite Purple Taaffeite

It's visible that the crystal shape is hexagonal (crystals are with 6-sides) - Metal_Treasure

The Contenders

Its crystals look like the crystals of aquamarine but are pink - morganite is actually pink beryl while aquamarine is pale blue beryl - Metal_Treasure

12 Peridot Peridot
13 Jeremejevite Jeremejevite

The image shows a chunk of a bigger crystal. Undamaged crystals of this gem look like amethyst crystals but are blue. - Metal_Treasure
