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 Item # to see a photo of the gem.  Use your browser's "back" button to return to the list.
