What's the difference between The Golden crystal?

Metal-coated crystals are natural crystals, such as quartz, whose surface has been coated with metal to give them an iridescent metallic sheen. Crystals treated this way are used as gemstones and for other decorative purposes. Possible coatings include gold (resulting in a stone called aqua aura), indium, titanium, niobium and copper. Other names for crystals treated so include; angel aura, flame aura, opal aura or rainbow quartz.

Aqua aura is created in a vacuum chamber from quartz crystals and gold vapour by vapour deposition. The quartz is heated to 871 °C (1600 °F) in a vacuum, and then gold vapor is added to the chamber. The gold atoms fuse to the crystal's surface, which gives the crystal an iridescent metallic sheen. When viewed under a gemological microscope in diffused direct transmitted light, aqua aura displays the following properties

The Golden Crystal is a supremely powerful crystalline artifact that was a major driving plot point in both Sailor Moon Super S and the Dream saga of the manga, though both their origins severely differ between the original anime and manga.

It is the Earth's equivalent of the Silver Crystal and equals it in strength and power. In the Cloverway English dub, it was known as the Golden Crystal of Dreams.

With her newfound strength and freedom, she uses the immensely strong, dream-infused abilities of the Golden Crystal against the five Super Sailor Senshi. The Amazoness Quartet steal the crystal from the queen and give it to Super Sailor Moon. Super Sailor Moon and Super Sailor Chibi Moon combine their power with the power of dreams from the people of Earth and it is used to seal.

Rainbow quartz have been treated with a combination of titanium and gold. Titanium molecules are bonded to the quartz by the natural electrostatic charge of the crystal in a process known as magnetron ionization. The brilliant color of flame aura is the result of optical interference effects produced by layers of titanium. Since only electricity is used to deposit the titanium layers and create these colors, very little heat is involved and the integrity of the golden crystal is maintained. The crystal does not become brittle or prone to breakage as with other treatments.
