Blue Gold? Would you?

In researching gold for an upcoming blog I stumbled upon these stunning rings. Each ring has a different level of blue gold from light to deep, dark, almost black blue gold.


The band ring, above, a very deep, almost black gold, has Tanzanite and Diamond gemstones.  The band is for sale by Diamondere.  See for details.


This ring, immediately below, is a medium dark blue gold band with one Pink Sapphire gemstone.

Intermetallic compounds, as these three blue gold rings, are obtained by fusing a strictly fixed ratio of components determined by the chemical formula. These metals are characterized by having low plasticity and high fragility — they can crack or be fractured after the fall or become dented from a blow, so it limits their broader usage in the jewelry industry.


Blue gold is a gold alloy with indium — AuIn2, containing 46 percent of 11-carat gold and 54 percent indium. The blue intermetallic compound is very fragile.


The compound of gold and gallium — AuGa2 has a lighter bluish hue and contains 58 percent of 14K gold. This gold alloy is more solid than AuIn2.


Jewelry pieces made of blue gold are rare.

During the 1970s I began making and selling jewellry, a passion I shared with my mum, through local businesses. Together, we made hundreds of pieces of everyday accessories to wedding accessories. From 1980 to 1993 I was an integral part of the team of successful small business entrepreneurs behind Boaz Junction, a local women's wear store here in St. Catharines, Ontario.
