An elegant one of a kind genuine antique Art Deco period traditionally handmade unheated untreated denim blue natural sapphire and old cut diamond 14K white gold filigree bombe ring circa 1925, 6.8 carats total gem weight.
This unique antique ring is completely handmade with gorgeous workmanship and elegant period detail. To me the design is a little like a daisy or flower but it is also abstract too. With an overall bombe or dome shape there is a definite silver screen luxury appeal and an elegance and exuberance of the luxury of another time- jazz age glamor! It's easy to see this luxury ring worn with a mink cape and a bias cut slinky figure hugging silk gown to a party with jazz musicians playing...not surprising too because that is exactly the time this ring was made and the lifestyle enjoyed by the elite of society when this ring was made.
The sapphire and diamond cluster itself measures approximately 13/16" in diameter by 1/2" high off the finger - it makes a big splash on the hand and is perfect as a one of a kind exuberant engagement or anniversary ring or that dazzling cocktail ring. Actually as you can see in the photos the stunning sapphire and diamond cluster covers the whole finger from side to side.
The sapphires are lovely indeed and have a color variation between inside lighting conditions and full sun outdoors. Outdoors the color of these unheated untreated sapphires is a medium denim blue and indoors I would describe the color as denim a blue with a dash of gray spun into the color. Like all sapphires different lighting conditions will result in slightly different hues/shades and that effect is very beautiful in these particular stones. The central cabochon is a little darker than the six surrounding cabochons. There are some light chatoyant inclusions to some of these cabochons with most being eye clean- the sapphires are transparent except for a single translucent/semi-transparent stone. There are no modern treatments, no heat treatment these fine gem quality sapphires have been polished only and are just as mother nature made them. The total sapphire weight is 5.8 carats.
Decorating the outside of the floral dome there are old cut natural sparkling white diamonds, a total of 48 with a combined diamond weight of 1 carat as estimated in the setting. These are F/G in color and mainly VS/I (mainly VS a very few SI and one I) in clarity. At the time of this ring was made it is important to note that modern diamond grading standards were not in use. This is a genuine period ring.
The combined sapphire and diamond weight is a substantial 6.8 carats.
Currently a size 7 US, it is sizable within a range, please enquire.
Inside the shank a metal fineness mark "14K" can be clearly seen, this meaning of course solid 14 karat white gold and confirmed also by testing.
The ring weighs 5.96 grams
The gallery of the cluster is decorated with feminine lace like filigree white gold decorations that can be seen from the sides also when the ring is on the hand.
This is an extraordinary one of a kind genuine antique unheated blue sapphire and diamond Art Deco ring is in lovely condition and is ready to gift or to wear.

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 sapphires 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, deep diffusion and beryllium treatment. In recent years sapphires 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. Colored coatings can be applied to the back of a sapphire. These treatments are unacceptable and such treated stones are of very low value. We do not sell sapphires with these treatments. Actually all the sapphires in this ring are unheated and untreated just as mother nature made them having only been cut and polished into lovely cabochons. It makes a beautiful choice for a very special sapphire celebration such as a birthday, engagement or anniversary to be handed down in the family for generations to come.
