Aura quartz is not dyed, painted, or artificially coloured. Its extraordinary iridescence is the result of a precise scientific process called vapour deposition — a technique in which natural quartz crystal is placed in a vacuum chamber and bonded at the atomic level with vaporised precious and semi-precious metals. The result is a permanent, interference-based colour that shifts with light and angle, produced not by pigment but by the physics of thin-film optics.
Each variety of aura quartz owes its distinct colour to a specific metal or combination of metals. Understanding what goes into each stone is part of what makes them so compelling — and so enduring.
The Aura Quartz Varieties
Angel Aura Quartz — Platinum & Silver
Angel Aura Quartz is produced by bonding clear quartz with a combination of platinum and silver. These two metals, when vaporised and fused to the crystal surface, create a soft, pearlescent iridescence — pale whites and silvers that shift into blush pinks, lilacs, and pale golds depending on the angle of light. Platinum is one of the rarest and most chemically stable metals on earth, which is part of what gives Angel Aura its exceptional clarity and longevity of colour. The finish is refined, luminous, and unmistakably precious.

Rainbow Aura Quartz — Titanium & Niobium
The most visually dramatic of the aura quartzes, Rainbow Aura is created through the bonding of titanium and niobium onto clear quartz. Titanium is the hardest of the metals used in aura quartz production and produces the widest visible spectrum — the full range of violet, teal, gold, and rose that gives this variety its name. Niobium, a rare transition metal, contributes additional depth and complexity to the colour shift. The combination results in a surface that behaves almost like a prism, refracting light differently at every angle. The colour is not a coating — it is a structural phenomenon, permanent and scratch-resistant.

Aqua Aura Quartz — 24-Karat Gold
Aqua Aura Quartz is one of the most technically precise varieties to produce. Clear quartz is bonded exclusively with pure 24-karat gold — and it is this single-metal process that yields the stone's signature deep sky-blue colour. At first glance, gold producing blue may seem counterintuitive, but it is a well-documented optical phenomenon: when gold is deposited in an extremely thin layer onto a transparent surface, it absorbs red and yellow wavelengths of light and reflects blue and teal. The thinner and more uniform the gold layer, the more vivid and consistent the blue. The result is a stone of striking depth, with flashes of violet and teal that emerge as the light shifts.

Ruby Aura Quartz — Platinum & Gold
Ruby Aura Quartz is produced by combining two of the most coveted metals in the world: platinum and gold. It is this dual-metal bonding process that creates the stone's rich, warm red-pink tones — a colour range that sits between rose and deep ruby depending on the thickness and ratio of the metal layers applied. Platinum provides structural stability and a cool undertone, while gold introduces warmth and depth. Together, they produce a colour that is simultaneously bold and refined — one that reads differently under natural light versus artificial light, giving the stone a dynamic, living quality.
Our Ruby Aura Quartz pieces are available across a range of metal finishes:
- Ruby Aura Quartz Crystal Point Necklace — Antique Bronze
- Ruby Aura Quartz Crystal Point Necklace — Soft Silver Finish
- Ruby Aura Quartz Crystal Point Necklace — Warm Gold Finish
Clear Quartz Aura — Titanium
Clear Aura Quartz is treated with titanium alone, applied in a thinner layer than Rainbow Aura to preserve the stone's natural transparency while adding a subtle, shifting iridescence. The result is a crystal that retains its clarity and brilliance while gaining a faint spectral quality — a whisper of colour rather than a statement. Titanium's exceptional hardness and biocompatibility make it one of the most durable metals used in the vapour deposition process, ensuring the finish remains pristine over time.
