03 — Finished jewelry
Jewelry
Set in the United States. Each piece names the stone inside it, and the centre stone’s origin, weight and oil grade travel with it on a printed card and on the appraisal.
| Piece | Centre stone | Enhancement | Metal | Price |
|---|---|---|---|---|
| Solitaire, 18k yellow gold | 1.02 ct, Muzo | Minor, cedar oil | 18k yellow gold | $4,850 |
| Three-stone band, platinum | 0.74 ct, Chivor | Insignificant | Platinum 950 | $6,400 |
| Bezel pendant, 14k white gold | 1.46 ct, Coscuez | Moderate, cedar oil | 14k white gold | $2,275 |
Each piece names its centre stone. The grading language on the card is explained in our provenance notes, and pieces over one carat ship with an independent laboratory report.
The fact that governs everything
Emerald is hard but not tough — and the difference is what breaks rings
Emerald sits at roughly 7.5 to 8 on the Mohs scale, which means it resists scratching well. Buyers hear that and assume durability. Hardness and toughness are different properties, and emerald’s toughness is generally poor. The same internal fractures and inclusions that make an emerald an emerald are planes of weakness, and a sharp knock on a hard edge can chip or crack a stone that would never have scratched.
Everything else on this page follows from that one sentence. Emeralds are not fragile ornaments — they have been worn for five centuries — but they must be set and treated like what they are.
This is also why the emerald cut exists. Its truncated corners were developed specifically because pointed corners chip during setting and wear. The cut is an engineering solution that happens to look good.
Settings
What protects an emerald, and what quietly endangers it
| Setting | Verdict | Why |
|---|---|---|
| Bezel | Best | A metal rim wraps the girdle, so the stone’s most vulnerable edge cannot meet a door frame. The single best choice for a ring that will be worn regularly. |
| Halo, or protective prongs with a raised gallery | Good | Surrounding stones and metal take the impact first. Corners stay covered. |
| Standard four- or six-prong | Acceptable, with care | Fine for pendants and earrings. On a ring, the corners and girdle sit exposed — workable if the prongs properly cover the corners rather than pinching near them. |
| Tension setting | Avoid | It holds the stone by continuous compression. Applying sustained pressure to a fractured gemstone is exactly the wrong idea. |
| Channel set, flush with a hard edge | Risky | Setting and later resizing require pressure and often heat close to the stone. |
Tell your bench jeweller it is an emerald before any work, including resizing, polishing or re-tipping a worn prong. A torch used near a set emerald can drive the filler out of the fractures and can crack the stone. Competent jewellers remove the stone first. Many emeralds are damaged during routine repair of the metal, not during wear.
Care
How to clean an emerald — and the two machines that destroy them
Never put an emerald in an ultrasonic cleaner, and never steam clean it. This is the most common way good emeralds are ruined, and it usually happens at a jewellery counter offering a free clean. Ultrasonic vibration can propagate existing fractures and strip filler out of them; steam adds heat, which does the same faster. A stone can come out visibly worse than it went in, and the damage is not reversible.
What to do instead
- Lukewarm water with a little mild dish soap.
- A soft brush — a baby toothbrush is ideal — working gently behind the stone where residue collects.
- Rinse in lukewarm water and pat dry with a soft cloth.
What to keep it away from
- Acetone, alcohol, solvents and commercial jewellery “dip” cleaners — these dissolve or leach the filler.
- Sustained heat and long direct sunlight, which dry out cedar oil.
- Chlorinated pools, household cleaners and hairspray.
- Gardening, gym work, DIY and washing up. Take the ring off — impact, not chemistry, is the usual killer.
Oiling is not permanent. Over years, cedar oil can dry or seep and a stone may begin to look tired — fractures that were faint become visible. This is normal, not damage, and re-oiling is a routine job for a gemologist or experienced bench jeweller. Ask us and we will point you to someone rather than guess.
Choosing
Match the piece to how it will actually be worn
| Piece | Exposure | Guidance |
|---|---|---|
| Pendant | Low | The safest way to wear a fine emerald. Hangs clear of impact. A larger or more valuable stone makes most sense here. |
| Earrings | Low | Very safe. Almost never struck. |
| Ring, occasional wear | Medium | Good with a protective setting. Take it off for anything physical. |
| Ring, daily wear | High | Hands hit things constantly. Bezel set, accept that it will need checking, and consider whether a stone with lower enhancement and a slightly lesser colour is the wiser buy — a heavily filled stone is a heavily fractured stone. |
| Bracelet | High | Wrists strike desks and door frames. Protective settings only. |
Questions
Emerald jewelry, wear and care
Can I wear an emerald engagement ring every day?
Yes, with the right choices and realistic expectations. Bezel or halo set, in a stone with minor rather than moderate or significant enhancement, checked by a jeweller periodically like any ring with a valuable stone. What you should not do is buy a heavily oiled bargain stone for daily wear — heavy filler means heavy fracturing, and daily wear will find it. Many people wear emerald rings for decades; they are simply people who take the ring off to garden.
Does an emerald need re-oiling, and how often?
Not on a schedule — only when it starts to look different. Some stones go decades. Others need attention sooner, especially after heat, solvent exposure or an unwise ultrasonic clean. The sign is fractures becoming more visible than you remember. A gemologist can re-oil it, and it is a modest job, not a repair.
What if my jeweller says ultrasonic cleaning is fine?
Find another jeweller for this piece. It is not a matter of opinion — ultrasonic and steam cleaning are contraindicated for filled emeralds by every gemological authority, and a jeweller who does not know that is telling you something useful about their coloured-stone experience.
Can you set a stone I buy from you?
Yes — mounting is quoted separately from the stone so you can see both numbers. We can also simply sell you the loose stone and recommend what setting style suits it, if you have a jeweller you already trust. We would rather you used a bench you know than have us insist on ours.
