Creators note:

I designed this ring with the idea of balance—minimal yet sculptural, simple yet bold. Its slightly more substantial weight gives it a presence that feels just right, distinct from more traditional delicate rings. The form is clean and modern, with a quiet strength that makes it effortless to wear yet meaningful in its expression. The small lab-grown diamond is just as intentional—subtle but significant, adding a touch of light and purpose to the design. To me, it’s a piece that carries both elegance and confidence, a small but powerful statement on the hand.

Your FORMÉS Diamond Guide

Let’s find the diamond that feels right—for your values, your story, and your light.

1. Natural or Lab Grown? Two Beautiful Journeys

	Natural Diamonds	Lab Grown Diamonds
How it’s made	Earth-formed over 1–3 billion years	Created in labs in 4–10 weeks
Eco impact	~108–160 kg CO₂ per carat	From as low as 0.03 to 500+ kg CO₂ depending on energy source
Why people choose	Rarity, long-term value, timeless origin	Ethical, sustainable, modern tech story, more size for your budget
Certification	GIA, HRD, IGI, SCS 007 (sustainability)	GIA-LGDR, IGI, HRD, SCS 007

At Formés, we request full energy-source info for every diamond we offer—transparency first.

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!

4. Diamond Certification — What to Look For

Lab	For	What it tells you
GIA	Natural & Lab Grown	Top-tier grading, laser-inscribed ID
IGI	Natural & Lab Grown	Widely used in lab diamond world
HRD	Natural & Lab Grown	Trusted in Europe, great on origin checks
SCS 007	Both + Recycled	Sustainability scoring, ethics guarantee

Every Formés stone comes with a trusted certificate and laser-inscribed ID.

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.

Rich, saturated color (think late-sunset glow)

Ring Size Guide

RING SIZE CONVERSION CHART BY FORMÉS

FORMES Ring Size Guide

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.
Warm weather = slightly larger fingers; cold = slightly smaller.
Wide bands (6mm+) feel tighter—go half a size up.
Slim stacking rings? Choose a snug fit.

What About Ring Style?

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.
