Retro c1940s Aquamarine and Ruby Tank ring by Crosby 14k Rose goldThis ring is a direct result of the historical influences of the time. These mainly came from the emergence of World War II and we saw this affect the supply of white metal for jewellery, particularly platinum. Platinum was a favourite in in the Art deco period and its requisition for the war made is scarce and in a lot of places prohibited. Due to this change we saw the heavy switch to rose gold like this ring. Not only was the supply of metal

This ring is a direct result of the historical influences of the time. These mainly came from the emergence of World War II and we saw this affect the supply of white metal for jewellery, particularly platinum. Platinum was a favourite in in the Art deco period and its requisition for the war made is scarce and in a lot of places prohibited. Due to this change we saw the heavy switch to rose gold like this ring.

Not only was the supply of metal affected but so was the supply of gemstones. A lot of mines closed due to lack of workers and the trade routes being affected. This affected the supply of diamonds and alot of gemstones, pushing jewellers to use more affordable and larger gemstones over diamonds. This saw the popularity of large aquamarines  and citrine's rise with smaller diamonds and rubies then used as accent stones. 

Perhaps the most notable style to emerge was the 'tank style' this style took the architectural & geometric design seen in the late 1930s and the boxy yet flowing design of the war tanks as inspiration for a new style. Often open worked galleries with swirling ribbons and vilutes of gold and high open paneling were featured. Their popularity has really peak in the last few years and they are being given the spot light they deserve like this stunning example. This asymmetric design houses a striking natural aquamarine with three synthetic rubies accent gems

The gallery is pierced with a fan or shell shaped embellishment, the shoulders taper to a flat profile shank in the quintessential tank ring style. It has been valued at $12,600 and encompasses every feature discussed above so she is a historic piece. Hallmarked 14k Crosby and tested 585 14ct. Crosby was an American company active in the 1930 & 1940s

it's not bad
a coffee, tea, and alcohol drinker so i've gone thru a few of these. i knew i wouldn't see immediate results so i just tried to consistently brush my teeth with this. i can't say it made my teeth whiter but i think it brightened my teeth and helps to prevent it from staining? i didn't irritate my teeth or gums which is important, it helped my mouth to feel cleaner or was it bc of the flavors in it that makes it feel like that? also this little container is too expensive!

Great Product
Its a good product. It works gradually whitening teeth. I use this powder on top of the Boka Prebiotic toothpaste and I have to say I am pretty impressed how clean my teeth are, the whitening and no sensitivity issues.

Awful packaging
Just got the product so I can’t give opinion on if it works to whiten my teeth but I will say the packaging is awful. The powder gets all over the lip of the container and all over the sink. Hard pass unless you want to clean your sink each time you use it.
