I'm crazy for the rustic biomorphic forms of the Organic Modernist era jewelry of the 1970s! Textured flowers, leaves and roots. They provide a warm and natural contrast to the shiny machined look of today's jewelry. They used a lot more gold for the scale of a piece, too... they certainly don't do this nowadays!

This solitaire is by notable jewelry design team Northwest, who are still in business today. All their vintage pieces are quality and this one is no exception!

Frequently asked questions about AuldBaubles

Vintage/Antique baby/children's jewelry almost certainly does not meet metals safety standards for youngsters of today. Therefore I can only sell it for adult use.

I cannot guarantee sterility of earring posts/hooks/wires (and/or other pieces where this may be an issue). Please purchase and use at your own risk.

May try to sell you work your ring doesn't need! Be on your guard, refer to Item Details for info re: prongs and bands.

Colors may display inaccurately on screens.
RING SIZES are approximate, due to jewelers' ring sizing mandrels not being completely standardized.

STONE SIZES are necessarily estimates, because in most cases, I cannot measure the depth of a stone due to its being in a setting. I measure the diameter (or length and width) of a stone with digital calipers, and estimate its carat weight from its span.

BANGLE SIZE: Please note the inner diameter for the bangle. I suggest you cut out a mock-up on sturdy cardboard to see how it will fit you before ordering.
The outer packaging is discreet, nobody will know there is jewelry inside.

I do not use my shop name on the return address; this is for the item's safety in transit and for privacy on arrival, as jewelry items are often bought as gifts.

Pieces are sent in small carton boxes tied with rustic string, or cushioned inside handmade wrapping paper gift bags.
