A beautiful unique unheated purplish red ruby and diamond engagement ring circa 1970, 14K gold circa 1970.
This beautiful 1.45 carat unheated untreated purplish red ruby is a very unique color! In direct sun the ruby is grape purple a stunning color so rare to see in sapphire. In other lighting conditions the ruby is a reddish purple a more plum color. The change in color is lovely in different lights and certainly quite a mysterious and very unique phenomenon with this wonderful ruby! The size for such a rare color in an unheated ruby is lovely - 1.45 carats and that this unique ruby a perfect choice for a one of a kind engagement or anniversary ring.
I adore the pretty asymmetrical setting with it's delicate splash of diamond accents.
The large purplish red ruby measures 10.3mm x 5.6mm x 3.4mm and weighs 1.45 carats and there are 3 points of G SI diamond accents.
This makes the total precious gem weight 1.48 carats.

The photos form part of the description. Like all colored stones there is a color variation that occurs in different lighting conditions both inside but also outside, even the time of day can make the color of a stone appear a little different. We do our best to show colors as we see them. Color perception is highly individual and some people can perceive more colors than others, also colors can appear somewhat different on different screens and devices due to variations in screen hardware and device display settings.
Comment:
Unfortunately, in the last two decades many rubies seen in modern jewelry and rubies set as replacements in vintage and antique jewelry have had the color induced by high temperature heating in chemicals such as beryllium. This is called diffusion treatment and includes surface diffusion, bulk diffusion, lattice diffusion and deep diffusion. There are also sapphires treated heavily with beryllium treatment to imitate rubies. In recent years rubies have been clarity enhanced by filling any fissures or cracks with molten lead glass, sometimes the glass is colored as well, with time the filler falls out or goes cloudy ruining the stone. Polymer resins can be used in a similar way. Oftentimes this clarity enhancement may appear on certificates as the note(s) “residues” or “minor residues” or perhaps “foreign substance”. Colored coatings can be applied to the back of a ruby. These treatments are unacceptable and such treated stones are of very low value. We do not sell rubies with these treatments. This ruby is unheated and untreated - the absolutely unique purplish red and the variation in color in different lighting conditions is wonderful and makes this ruby a lovely choice for a family heirloom to be passed down for generations to come.
