Finding your ring size should feel as effortless as slipping on your favorite piece. Whether you're choosing a gift or treating yourself, here's how to get the perfect fit at home.
Two Simple Ways to Find Your Ring Size
1. Measure Your Finger
Take a soft ribbon, string, or strip of paper and wrap it gently around your finger. Make sure it slides comfortably over your knuckle.
Mark where it overlaps and measure the length in millimeters.
That number is your finger’s circumference. For example, 54 mm means size EU 54.
Tip: If you're between sizes, go one size up. If you’re choosing a slim ring, you can opt for a slightly smaller size.
2. Measure a Ring You Already Own
Pick a ring that fits the intended finger.
Lay it flat and measure the inside diameter in millimeters across the widest point.
Match this diameter to our size chart.
Sample of size 15, or 15 mm inner diameter
Helpful Sizing Tips
Fingers on your dominant hand are usually a bit bigger.
Statement rings: If bold and wide, go half a size up.
Stacking rings: Measure the exact finger and go for a snug fit.
Knuckle/midi rings: These often run small—check specific design notes.
Engagement and wedding bands: Precision matters. Measure carefully or contact us for help.
Open rings: These are slightly adjustable but still follow our sizing guide.

18 K Gold – Heirloom Classic
75 % pure gold + 25 % lighter alloys
Rich, saturated color (think late-sunset glow)

2. The 4 C’s of Diamond Quality — Always the Standard
Both natural and lab grown diamonds are graded by the 4 Cs: Cut, Color, Clarity, and Carat. Here's what really matters:
Cut = how it sparkles → We only use Excellent or Very Good. It’s the most important C, as it is not nature's given characteristic, but a polisher's expertise and craftsmanship.
Color = how white it looks → We love the D–G range for its crisp, bright white look. While D–E diamonds are often chosen for investment, F–G diamonds offer the best balance of beauty and value—yellow tones are virtually invisible unless directly compared to D–E, so there’s no need to worry. When the design calls for it, warmer tones can be stunning too—these are often referred to as champagne, cognac, or even brown diamonds, and they bring character and a distinctive richness to the piece.
Clarity = how clean it looks → We pick eye-clean diamonds. IF–VVS stand for no or almost no inclusions and are mostly chosen for investment; VS and SI1 are optimized for everyday wear. If you can’t see inclusions, they won’t matter.
Carat = size and weight → Bigger isn’t always better. Let’s find your perfect proportion.
3. Choosing Your Diamond, Made Simple
Your Style
Natural Diamond Tips
Lab Grown Diamond Tips
Heirloom / Investment
D–E color, IF–VVS clarity, Excellent cut, GIA or HRD cert
D–F color, VS+ clarity, Excellent cut, GIA or IGI cert
Daily Wear / Modern Piece
F–G color, VS2–SI1 clarity, Excellent/Very Good cut
Choose what shines brightest to your eye—cut is key, clarity and color shifts cost less
💡 Fun fact: With lab grown, a clarity upgrade (e.g. VS to VVS) may only cost 5% more. In naturals, that could be 20% or more!

6. Fast FAQs
Will a lab-grown diamond keep its value? Buy for love, not resale. Tech evolves fast—brilliance, responsibility and ethics are the real return.
Are natural diamonds always ethical? Only when documented. We rely on trusted sources like GIA, SCS 007, and the Kimberley Process.
What matters more—cut or carat? Always cut. A well-cut diamond will sparkle more than a larger one with poor cut.
At Formés, we don’t just set diamonds—we translate your light. Choose natural or lab grown. Choose with heart. We’ll take care of the rest.
Recycle Your Gold for Gold Credit
Gold doesn't lose its worth — only its form.
Let us reshape it into something that matters. Recycle Your Gold for Gold Credit I’ve always found it quietly fascinating — how gold, no matter its past, can be melted down, purified, and given a second life. A forgotten piece can become something new. Something more personal. More true to you.
At FORMÉS, we welcome your solid gold jewelry — whether a single ring or a collection of old memories — and offer you Gold Credit in return. That gold is carefully refined by us and made ready for a new creation: a piece that carries only what you choose to keep. Color or karat doesn’t matter. Everything is melted and purified before it's reshaped — so what matters most is that it’s real gold, not plated or imitation.
