No Heat Ruby Ring 1950s Ruby Diamond Ring Flower Floral Engagement Ring 18K White Gold Handmade One

Appraisal Report included with your purchase. Exquisitely feminine, this gorgeous no heat untreated ruby diamond flower ring is beautiful indeed. This no heat natural red ruby and sparkly white diamond ring was made completely by hand in the early 1950s. It is a one of a kind ruby and diamond ring from the mid century era. Few modern rings are made entirely by hand because of the skill and cost involved in this work and even at the time this ring was made only very fine pieces were manufactured this way. Designed as a beautiful cluster it is floral in inspiration and all the more eye catching for the slight asymmetry of the design. The red rubies pop against the fine white diamonds, it's such a lovely ring! This special ruby anniversary ring is a size 7 US and can be resized. Inside the shank there is a metal fineness mark no longer visible shown in the photos. This ring has been tested professionally to be solid 18K white gold. It weighs 4.61 grams. The lovely diamond and ruby cluster measures 5/8" along the finger and sits 5/8" wide with a 11/16" rise off the finger (15.2mm x 16.5mm x 11.0mm). Beautiful too- the diamonds are old melee cuts which are just divine. There are 18 of these beautiful untreated natural earth mined white diamonds with G/H/I color and VS/SI clarity. The total diamond weight is 0.52 carats. The rubies are completely unheated untreated earth mined natural gem quality rubies- just faceted and polished as mother nature made them! In some lighting conditions the rubies in this ring show pink and purple tints as well as red. Unfortunately, in the last two decades many rubies seen in modern 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. The total ruby weight is 1.19 carats with the largest rubies weighing 23 points each! This brings the total diamond and ruby weight for this unique ring to 1.71 carats It is in lovely condition.

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.
