The golden rules
Six habits that keep it brilliant
Tap any card to see why it matters.
At-home care
Clean it at home in four steps
The safest, jeweler-recommended method for solid gold and platinum set with diamonds, moissanite, or durable colored stones.
01Step one
Soak
A bowl of warm — never hot — water with a few drops of mild dish soap. Let it sit for 15 to 20 minutes.
15:00
Ready when you are
02Step two
Brush
Gently work a soft or baby toothbrush around the setting, paying attention to the back of the stone, where oil and grime collect and kill sparkle.
03Step three
Rinse
In a second bowl of clean water — never over an open drain, so plug it first.
04Step four
Dry
Pat with a lint-free or microfiber cloth, and let it air-dry fully before storing.
Never use these
They erode gold alloys, scratch finishes, loosen stones, and damage treated or organic stones.
Chlorine & bleach
Toothpaste
Baking soda
Abrasive cleansers
Acetone & solvents
Vinegar on porous stones
Hot water or steam on delicate stones
Between deep cleans: wipe with a microfiber cloth dampened in a little soapy water.
A word on ultrasonic cleaners
Home ultrasonic machines are tempting but risky — they can shake an already-loose stone right out.
Usually fineClean, untreated lab diamonds, moissanite, sapphire, and ruby in solid gold or platinum.
NeverEmerald, opal, pearl, tanzanite, turquoise, and any treated, fracture-filled, or glued stone — and never if a stone already feels loose.
When in doubtHand-clean. It's gentler and lets you inspect the piece as you go.

Metals & stones, explained
The metals
Pure gold doesn't tarnish, but the alloys that make it durable can dull and react with chlorine and sulfur — so keep it away from pools and harsh chemicals. Clean with soap and water; a gold polishing cloth restores shine. 18K has a richer color; 14K is a touch harder for everyday wear.
It's yellow-toned gold alloy finished with a bright rhodium plating. That plating wears with daily contact and the warmer tone shows through — completely normal. A jeweler re-polishes and re-plates it, roughly every 12–18 months on a daily-worn ring and far less often for earrings and pendants. Clean it exactly like yellow gold.
Its blush comes from a copper alloy, which also makes it very durable. Over years it may develop a slightly deeper patina — many people love it. Soap and water is all it needs; there is no plating to maintain.
Naturally white with no plating to wear off, and wonderfully dense — it makes the most secure prongs. It does not lose metal when scratched; instead it develops a soft patina of fine lines. Leave it for a vintage look, or have a jeweler re-polish it to a mirror finish.
Sterling silver (925)
Solid 925 sterling silver naturally tarnishes on exposure to air, moisture, and sulfur — a regular, gentle pass with a silver polishing cloth restores the shine. Store it airtight in its own pouch or zip-lock bag with an anti-tarnish strip, separately from other pieces. Take it off before pools, hot springs, and household cleaning, since chlorine and sulfur accelerate tarnish, and keep lotion and perfume off the metal. An ultrasonic is generally fine for plain silver, but avoid it when soft gemstones are set in it — when in doubt, a soft cloth only.
The stones
The hardest material there is and built for daily wear — but it's a grease magnet, so the oil from a single touch dulls it fast. Clean it weekly and it sparkles like new. Protect it from hard knocks, which can chip even a diamond at the edge.
Extremely durable and easy to live with. Like diamond, it attracts oils and can look filmy, so a quick regular clean keeps its fire bright. Soap, water, and a soft brush are perfect.
Durable colored stones take soap, warm water, and a soft brush. Avoid harsh chemicals and sudden heat.
Treat gently: no ultrasonic, no soaking, no chemicals or perfume. Wipe with a soft, barely-damp cloth. Pearls should be wiped after every wear and restrung every few years if worn often; opals dislike very dry air and sudden temperature changes.
The Mohs hardness scale
Tap a stone to see what its hardness means for daily wear.Hardness is scratch-resistance, not toughness. Your Signora diamonds and moissanite sit at the very top — ideal for everyday rings — while softer stones are happiest in earrings and pendants that take fewer knocks.

The hardest material there is — built for everyday rings. Nothing in normal wear will scratch it, though a sharp knock on the edge can still chip it. Clean it weekly and it always comes back to full sparkle.
Storage & everyday wear
Where it lives when you're not wearing it
Keep pieces apart
Store each piece in its own soft-lined compartment or pouch. Diamonds and moissanite will scratch every other stone and metal they touch — never pile jewelry together.
Chains
Hang them, or lay them flat and fasten the clasp so they can't knot.
Lining
A fabric- or anti-tarnish-lined box protects finishes.
Climate
Keep jewelry out of direct heat; very dry air can harm opals and pearls.
Travel
Use a padded travel case with separate slots; never loose in a wash bag.

Repairs — an honest note
We don't run a mail-in repair desk —
We don't run a mail-in repair desk —
and that's deliberate
We make your piece in Surat, the diamond-cutting capital of the world, and ship it to you directly. Because of that, we don't run a mail-in repair service — sending fine jewelry across borders for a small fix is slow, costly, and risky for something this precious.
What we can do is make sure any repair is easy and safe: below is exactly how to tell what's needed, how urgent it is, and what to ask a trusted jeweler near you. And our care team is always on WhatsApp if you'd like us to look at a photo first.

Repair triage
Is it DIY, or a jeweler's job?
Pick what you're noticing — we'll tell you what it means, how urgent it is, and exactly what to ask for. (Spoiler: fine-jewelry repair is almost never a DIY job.)
Choose a symptom and we'll walk you through what to do.
Never attempt fine-jewelry repair, soldering, or super-glue at home — it almost always increases the final bill and can damage the piece beyond an easy fix.
Common repairs explained
What each repair actually involves
Rough costs are a US guide only and vary by jeweler, region, metal, and design — always get a written estimate.
Prong re-tipping / tightening
The most important repair. Prongs wear from daily contact, and loose prongs risk your center stone. Have them checked every 6 months.
~$25–75 per prongRing resizing
Fingers change with weight, weather, and age. Most rings move 1–2 sizes; eternity, channel, and full-pavé bands are hard or impossible to resize.
~$40–100Rhodium re-plating (white gold)
Restores the bright white finish as the plating wears. Typically every 12–18 months on daily-worn rings.
~$40–150Chain soldering / clasp
Re-joins broken links or swaps a worn clasp; ask them to test the whole chain for other weak points.
~$25–60 solder · ~$20–50 claspStone tightening / replacement
Re-secures a loose stone or sets a matched melee. For a lost center stone, this is what insurance covers.
Accent ~$30–100Re-polishing
Removes scratches and restores luster — and re-plates white gold at the same time.
Often part of a servicePearl restringing
For pearl pieces, every few years if worn often, before the thread weakens.
Varies by length
At the jeweler
What to ask your local jeweler
How to choose one
Pick a shop with a bench jeweler on-site who does the work in-house — your piece should never be shipped out.
Look for credentials and reputation: a trained goldsmith, Jewelers of America or American Gem Society affiliation, and strong long-standing reviews.
Insist on a written estimate and intake photos before any work begins.
Ask whether your piece is insured while it is in their care.
Ask if they can handle your specific setting — pavé, channel, halo, tension — without damaging it.
Protect your stone
This is how you guarantee you get your stone back.
If your Signora lab diamond carries a laser inscription (noted on the certificate), ask them to verify that number at drop-off and again at pickup.
If it isn't inscribed, ask them to photograph it and note a recognizable inclusion under magnification on the repair ticket.
Copy-and-paste scripts

Loose stone
"One of my stones feels loose — can you tighten it and check all the prongs under magnification before it's at risk?"
Worn prongs
"My prongs are worn and catching on fabric — can you re-tip or replace them and re-secure the center stone?"
Resize
"Can you resize this from size ___ to ___? Will it affect the design or stones, and will you re-secure everything afterward?"
White gold
"My white gold has turned warm/yellow — can you re-polish and re-rhodium plate it?"
Chain / clasp
"Can you solder this broken link / replace the clasp, and test the rest of the chain for weak points?"
Stone protection
"My diamond is lab-grown and certified — here's the inscription number. Can you verify it when I drop off and when I collect it?"

Care & repair FAQ
Better not to. Take pieces off before showering, swimming, and the gym — chlorine, saltwater, and sweat are harsh on gold alloys, and lotions and oils film up stones. A good habit is last on, first off: jewelry goes on after you're ready and comes off first at day's end.
A gentle soap-and-water wash weekly keeps a daily-worn ring bright; occasional pieces need it less often. Between deep cleans, a quick wipe with a microfiber cloth lifts the oils that make diamonds and moissanite look dull.
Sometimes — clean, untreated lab diamonds, moissanite, sapphire, and ruby in solid gold or platinum usually take it well. Never use one on emerald, opal, pearl, tanzanite, turquoise, or any treated or glued stone, and never if a stone already feels loose, since the machine can shake it right out. When in doubt, hand-clean.
No — that's completely normal. White gold is finished with a bright rhodium plating over a warmer gold alloy, and the plating gradually wears with daily contact. A jeweler re-polishes and re-plates it, roughly every 12–18 months on a daily-worn ring.
We don't, and it's deliberate. We craft and ship from Surat, and sending fine jewelry across borders for a small fix is slow, costly, and risky. Instead we show you exactly what's needed and what to ask a trusted local jeweler — and our care team will happily look at a photo first on WhatsApp.
If your Signora lab diamond is laser-inscribed (noted on its certificate), ask the jeweler to verify that number at drop-off and at pickup. If it is not inscribed, ask them to photograph it and note a recognizable inclusion under magnification on the repair ticket.
