Top 10 Gemstones with the Most Beautiful Rough Crystals

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 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

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

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

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

4 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

5 Elbaite
6 Red Beryl (Bixbite)

The rarest type of beryl, only found in the Wah Wah Mountains in Utah! - AlmndButtrToast

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

7 Watermelon Tourmaline
8 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

Why is this not higher on this list?

10 Purple Taaffeite

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

The Newcomers

? Realgar

Realgar is also a deadly yet beautiful mineral. It's an ore of arsenic, but it has amazing red and orange crystals! - AlmndButtrToast

? Cinnabar

Cinnabar is a deadly yet beautiful mineral - it's the main ore of mercury, but the crystals are a deep red. - AlmndButtrToast

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
