Lab Grown Synthetic Blue Sapphire
|
Although sapphires come
in almost every color except red (which is designated ruby), the traditional
color one thinks of is a deep blue. Our lab grown or
created synthetic blue sapphire gems are synthesized from the melt at
temperatures over 2000 oC or 3600 oF. They have
the same composition and physical properties, but have higher perfection than is usually
seen in natural sapphires. Sapphire is
aluminum oxide, or corundum, with the chemical composition Al2O3.
Various dopant atoms present in small
amounts provide the different colors. Chromium (Cr) gives the ruby red
color. Blue is trickier because both titanium (Ti) and iron (Fe) must be present as dopants and on neighboring sites in the crystal lattice,
and they must be in the proper valence state which chemists designate
as Ti4+ and Fe2+. Charge transfer between the
two species gives rise to the light absorption causing the sapphire blue
color. Neither Ti4+ or Fe2+ is easily
incorporated in Al2O3
and most natural sapphire is not blue. Even when both elements are
present, they are usually not in the proper valence state.
Consequently almost all "natural" blue sapphire on the market has
been heat-treated before sale to enhance the blue color. An exception
is the blue sapphire from Yogo Gulch, Montana. We are able
to offer lab-grown blue sapphire gemstones at a small fraction of the cost of comparable natural
sapphire stones. We can also set these gemstones for you in silver or
gold jewelry mountings. Ask for details. You can click on any underlined
