Jewellery Reno: Mum's emerald had a secret
Miriam inherited her mother's ca. 1940 three-stone diamond and emerald engagement ring. She wanted to reset the emerald as a modern ring she could wear everyday and one day pass it on to her youngest daughter.
Miriam lives several hours from Toronto, so visited a jeweller I recommended, Pam Chandler of Artwork Gallery. Miriam liked their clean, modern pieces, and asked Pam for ideas.
Tip #1: Someone may recommend a jeweller, but it's essential that you like what you see when you visit, which reflects the artist's sensibility. Jewellers design within their style range; avoid one who says he can "make anything".
Two wax models
The jeweller made waxes of a three-stone modern band. This is the process for a cast metal setting, and gives the client and idea of scale and shape.
Left: The first model was an oval, slightly bombé band with rounded edges. Miriam thought this was not exactly it.
Right: Miriam chose the second version, a uniform, knife-edged band, designed to use all the original stones and recycle the 14k yellow gold. (That sapphire and diamond band is an Artwork ring they looked at as an example.)
Tip #2: If the first try is not your ideal ring, ask for more options. You'll want to be entirely happy and this is the stage to get the shape and scale right.
Trouble in paradise!
Though some jewellers set their own stones, often a setter handles this work. And at this stage, Miriam got a shock. When he examined the emerald, the setter found it was a doublet, which is a thin layer of emerald glued to another, far less costly substance, in this case, glass. Emeralds, opals, and other gemstones are sometimes made into doublets in order to lower the cost.
The process is not considered deceptive if the practice is disclosed. These are not fakes (such as glass or other material sold as an emerald); they are assembled gems. Triplets also exist; in this case an additional clear layer is added to the top of the gem, usually glass or clear quartz.
Did Dad know the ring he chose was a doublet? Did Mum? It was treasured—and whether anyone knew is lost to time.
The setter would not reset the doublet because of the risk of shattering. Setting an emerald, always an included stone, takes nerves of steel, and a doublet is even more finicky because the emerald layer is thin. Miriam had a choice: take the risk (probably with a different setter), or replace the stone.
Pam suggested a green tourmaline, and sent Miriam a shot of it sitting loose in the setting, which was partially completed. Miriam liked this stone.
Tourmaline is fairly tough, but under a microscope this one showed many inclusions; therefore, the setter thought it might not withstand the force of the hammer. (A claw setting is much more accommodating.)
Tip #3: If you are willing to buy another stone, you might take a chance, but I have always respected an expert setter's judgement. There's an axiom that "Any stone can be set; it just depends how", but in this case the setting dictated the stone.
On the hunt for glowing green
Back to gem shopping! Fortunately, Miriam was in the hands of a jeweller with very high standards and superb taste in stones.
Pam sourced a 5mm chrome diopside, a rich green gem that's slightly softer than tourmaline, but in this protected setting, and with Miriam's loving care, it will be fine. When well-cut, chrome diopside is an exceptionally vivid stone and the colour is natural, never enhanced.
A new and whole stone
Left: Pam sent Miriam a photo of the finished ring; Miriam had one more trip to make into the city!
Right: On Miriam's hand, a beautiful blend of old and new. The ring fits perfectly; the back of the band is slightly flattened to minimize shifting. As Miriam says, her daughter will have the new gem to connect her to her mother, and the diamonds to connect her to her grandmother.
Tip #4: Jewellery restyling is both art and science. If the science doesn't line up—the gem isn't what you supposed, or it is weakened by wear or internal flaws—be prepared to look at replacements. Fortunately, in sizes under about 6mm, there are many bewitching coloured gems at very reasonable prices.
Miriam was delighted not only with her new ring, but with the process, and that's a credit to her equanimity. She learned a good deal about gemstones with this project, and took her time to consider her options. Miriam's doublet could still have another life—it's very pretty—as a clasp, pendant or ring that accommodates its true composition.
Had she preferred the vintage setting, she may never have known its secret. Now she does, and has a story to tell, as well as a new ring to enjoy.

Comments
Definition 2.3 comes closest to the gem-related one.
I confess to a certain nostalgia for the wartime setting; the one my mother had in wartime Ottawa was more modest still, as they were working in the civil service (my dad had a medical exemption) but guess I watched X Company a bit too closely... Their pay was far from opulent.
The only gem that takes daily wear in stride is diamond. Many buyers have been politicized away from diamonds, but there is an easy solution: buy Canadian. I am not promoting diamonds (which I love, in artful settings, not just a rock on a piece of pipe), but if you want a stone to take wear, that's the one. (The wearer can also damage a diamond- they are not impervious but pretty tough.)
I have also seen some gawdawful restyling- naturally I don't post those.
Jane, I trust you're having those prongs checked regularly to assure that your beautiful stones stay securely set.
