Repurposed lab sapphire and rubies are manufactured from scrap corundum crystals (corundum is the scientific name of sapphire and ruby). We focus on crystals grown using the Czochralski growth method which have the purity standards for scientific applications. The resulting monocrystalline materials are identical to natural sapphire and ruby in chemistry and hardness. Chromium doped laser ruby exhibits red fluorescence.

Pigeon Blood Laser Ruby
Czochralski grown ruby is classic laser rod material. Pigeon blood laser ruby has the perfect amounts of chromium dopant levels to achieve a pure red color. Pigeon blood rubies will fluoresce red in the sun and under blacklight. The vivid fluorescent red color of this particular type of laser ruby mimics the color of natural rubies that can sell for up to 1 million dollars per carat.
Jedi Laser Ruby
Jedi Laser Ruby has chromium dopant levels between pigeon blood and pink laser rubies resulting in an electric magenta color that mimics natural "Jedi Spinels." Jedi laser rubies will fluoresce red in the sun and under blacklight..
Pink Laser Ruby
Rubies can't be pink! While that is true, in laser science, any sapphire doped with chromium is called "laser ruby" to differentiate them from "pink laser sapphire" (Titanium Sapphire). Pink laser ruby has a lower chromium dopant level than both pigeon blood and jedi laser rubies resulting in a vivid pink color. Pink laser rubies will fluoresce red in the sun and under black light.
Titanium Sapphire
Titanium impurities are thought to cause the blue color in natural sapphires, but in fact even the smallest trace amounts of iron in combination with the titanium creates the blue color. In controlled laboratory settings they can grow titanium doped corundum in an iron free environment resulting in pink crystals. Higher titanium dopant levels result in darker crystals. Darker material often has a secondary orange color mimicking a fine padparadscha sapphire. Titanium sapphire is also called "pink laser sapphire" and is primarily used as tunable laser material. They exhibit red/infrared under blue and green light.
Royal Blue Sapphire
Czochralski pulled sapphire doped with titanium and iron result in blue crystals. Blue lab sapphire are used as medical flash lamp filters. The royal blue color is achieved when a particular level of titanium and iron are used. The resulting gems cut from this material rival the finest sapphires in the world.
