The metal guide

Choose the Metal That's Right for You

Every Signora piece is handcrafted to order in the metal you choose — from warm 9K gold to enduring platinum. Eleven finishes across three metals. Here's how to pick yours.

Three metals, eleven finishes

Start Here

Gold

The classic, in three colors and three purities — so you can dial in exactly the warmth, durability, and budget you want.

Platinum

The rarest and most enduring: naturally white, the most secure setting for a diamond, and beautiful for a lifetime.

Silver

The most accessible way to wear the look — cool, bright sterling, loved with a little care.

Gold comes in three colors — yellow, white, and rose — each in three purities: 9K, 14K, and 18K. That's the choice you'll make below.

Metal Type — color & purity. Pick a family, and for gold, a color and karat.

Purity Sets the Karat; the Alloy Sets the Color

Karat (K) measures how much pure gold is in the metal — different from carat, a diamond's weight. Pure 24K is too soft for jewelry, so it's blended for strength and color. All three colors come in all three purities.

Higher karat is purer and richer in color, but a little softer; lower karat is harder and more affordable, with a paler tone. 14K is the classic balance, 18K the luxurious choice, 9K the durable, accessible one.

Yellow gold

How it's made

Gold + copper + silver

Finish & care

Naturally yellow; no plating; won't tarnish

Notes

The timeless classic; warmer and richer at higher karat

White gold

How it's made

Gold + palladium (nickel-free), then rhodium-finished

Finish & care

Bright silvery-white from the rhodium; a local jeweler re-plates it about every 12–24 months to keep it brightest

Notes

Loved with diamonds for its bright, cool look

Rose gold

How it's made

Gold + a higher amount of copper

Finish & care

Naturally pink; no plating; durable

Notes

Romantic and warm; deeper pink at 14K, softer blush at 18K

Color comes from the alloy, not the karat — an 18K yellow, white, and rose are all 75% gold. White gold is the one finish that relies on rhodium plating, so it's the one that asks for occasional re-plating.

The enduring one

Platinum: White Forever

Platinum is the rarest of the precious metals and, in many ways, the most enduring. Our platinum is Pt950 — about 95% pure — and naturally white, so it never needs rhodium plating and never fades.

Naturally white, permanently

No plating, no re-plating, no color change.

The most secure setting

Dense and tough; when scratched the metal moves rather than wears away, so it loses almost no material over decades — ideal for the prongs that hold your diamond.

Substantial feel

Noticeably heavier than gold — a platinum ring weighs roughly 60% more than the same ring in gold.

Develops a patina

Over years it takes on a soft, matte sheen many people love; a jeweler can polish it back to a mirror finish anytime.

Hypoallergenic

High purity and no nickel, so it's gentle on sensitive skin.

The accessible one

Silver

Silver is the most affordable way to wear a Signora design. Sterling silver is 92.5% pure (hallmarked 925), with a cool, bright tone. It's softer than gold and platinum and will gently tarnish over time — easily polished back — so it rewards a little care, and is best loved as an accessible or statement piece rather than a lifelong heirloom.

A Little Care Goes a Long Way

All gold +

Mild soap and warm water with a soft cloth; avoid harsh chemicals, bleach, and perfume; store pieces separately, since harder karats can scratch softer ones.

White gold +

Have a trusted local jeweler re-plate the rhodium about every 12–24 months to keep it at its brightest. Between times, clean it just like yellow gold.

Rose & yellow gold +

Easy-going — an occasional polish keeps them bright. Rose may deepen slightly over the years, with no plating to maintain.

Platinum +

Clean it like gold; polish to restore the shine, or enjoy the soft patina. It never needs plating.

Silver +

Polish to lift tarnish, and store it dry and airtight when you are not wearing it.

In every metal

Crafted the Signora Way

Whichever metal you choose, every piece carries our signatures — a comfort-fit band that sits easily all day, delicate inside-rim milgrain on our engagement rings, a hidden Signora stone set inside the band, and our wordmark engraved within the shank. Hallmarking is available on request, and every piece is made to order, just for you.

Questions, answered

Metal FAQ

What's the difference between karat and carat? +

Karat (K) measures gold purity; carat (ct) measures a gem's weight. Different words, different things.

Is 9K real gold? +

Yes — 9K is genuine gold (37.5% pure, hallmarked 375), not plated or vermeil. (Note: in the US and Canada, 10K is the minimum that may be marketed as "gold," so it's listed as 9K / 375.)

Does white gold change color? +

Its rhodium plating gently wears, so it is re-plated periodically — about every 12–24 months. We craft and ship from Surat, so a trusted jeweler near you keeps it bright; our white gold is palladium-based, nickel-free, and hypoallergenic.

Will rose gold fade? +

No — its color is built into the alloy. It may deepen slightly over years and never needs plating.

Is platinum worth the premium? +

If you want a naturally white metal that never needs plating, the most secure setting for your diamond, and a substantial feel, yes.

Which metal is best for sensitive skin? +

Platinum, 18K gold, or palladium-based white gold are the gentlest choices.

Which metal suits my diamond? +

White metals show off a diamond's whiteness; yellow and rose gold can flatter a warmer, more affordable diamond.

Can I have any design in any metal? +

Yes — every ring is made to order in all eleven finishes.

Are your pieces hallmarked? +

Hallmarking is available on request, marking the purity (375 / 585 / 750 / 925 / 950).
