How to measure: Wrap a thin strip of paper snugly around your finger, mark where it meets, and measure that length in mm — that's your circumference. For an existing ring, measure the inside diameter. Measure at end of day and size up if between sizes.

Adjustable chain: Every necklace ships on an 18" chain with built-in clasp links at 16" and 17" — no alterations needed. Simply fasten at a shorter link to wear it higher.

Finding the right length

Petite frame or high neckline

16" sits higher and works beautifully as a choker-style piece or for layering.

Most popular length

18" is the most universally flattering and works as a standalone or layered piece.

Layering tip

Wear one at 16" and one at 18" — the 2" gap creates a clean, intentional stagger.

Not sure how it'll look?

Hold a measuring tape or string to your collarbone at each length to preview placement.

Size Guide
How to measure: Wrap a flexible tape or strip of paper around your wrist, just below the wrist bone. Note where it meets — that's your wrist circumference. Size up if between sizes.

Bracelet size chart

Size Wrist circumference Bracelet length Fit
S 5.5 – 6 in 6.5 in Snug to comfortable
Standard Default 6 – 7 in 7 in Comfortable, slight drape
L 7 – 7.5 in 7.5 in Comfortable, relaxed drape

Prefer a looser fit?

Add 0.5" to your wrist circumference and choose the size above for a relaxed, stacking look.

Buying as a gift?

When in doubt, standard fits the widest range. It's easier to size up than down.

Size Guide

All our gemstones are AA or AAA grade. We stock only the top two tiers across sapphires, rubies, and emeralds — rich color, excellent transparency, and responsibly treated. The quality guide below explains what each tier means for each stone.

Select a stone

Ideal color — sapphire

Too pale◄ Ideal range ►Too dark

Our quality standard

PremiumAAA
Vivid royal or cornflower blue, excellent saturation, eye-clean or near eye-clean with minimal visible inclusions. Our AAA sapphires are sourced from Kanchanaburi, Africa, Australia, and Sri Lanka.
FineAA
Rich blue with strong color. Minor inclusions may be visible under close inspection but are not distracting. Sourced from Kanchanaburi, Africa, Australia, and Sri Lanka.

How we treat our sapphires

What we do
What we never do
Heat treatment only
We follow industry standard practice. Over 90% of fine sapphires worldwide are heat-treated to enhance color and clarity — it's universally accepted and does not affect value. All heat treatment is disclosed.
No glass filling or beryllium diffusion
These treatments mask a stone's true quality or introduce foreign elements to alter color. We never use them — and you'll never find them in our inventory.

Ideal color — ruby

Too pale (pink)◄ Ideal ►Too dark

Our quality standard

PremiumAAA
Deep, vivid red approaching the prized "pigeon blood" standard — strong saturation, eye-clean or near eye-clean clarity. Our AAA rubies are sourced from Burma, Vietnam, and Madagascar.
FineAA
Rich red to slightly purplish-red with good saturation. Minor inclusions are acceptable — in rubies, fine "silk" inclusions can even scatter light beautifully. Sourced from Burma, Vietnam, and Madagascar.

How we treat our rubies

What we do
What we never do
Heat treatment only
We follow industry standard practice. Heat treatment improves color richness and reduces cloudiness — it's accepted across the fine jewelry trade and always disclosed. The vast majority of fine rubies on the market are heat-treated.
No glass or lead filling
Glass-filling is a common shortcut used to make heavily included, low-quality rubies appear acceptable. It degrades over time and misrepresents the stone. We never use it.
Pink sapphire vs. ruby: Both are the same mineral (corundum). The distinction is color intensity — if it's a strong enough red, it's a ruby. The line is a matter of grading, and the two frequently look similar in lighter stones.

Ideal color — emerald

Too pale◄ Ideal ►Too dark

Our quality standard

PremiumAAA
Vivid, pure green with excellent transparency and strong saturation. Some natural inclusions ("jardin") may be present — a hallmark of a genuinely natural stone, and something we seek out with great care. Our AAA emeralds are sourced from Colombia, Zambia, and Brazil.
FineAA
Rich green with good transparency. Inclusions are visible but not distracting — strong color more than compensates. Sourced from Colombia, Zambia, and Brazil.

How we treat our emeralds

What we do
What we never do
Natural oil only
Our emeralds arrive already beautiful — we source them that way. After cutting, we apply just a touch of natural oil to let the stone's own color and depth fully come through. That's it. No filling, no altering, no masking. The stone you see is the stone as nature made it.
No synthetic resins or polymer filling
Synthetic fillers like Opticon and heavy polymer treatments can mask a stone's true quality. We never use them — our emeralds are treated only with what nature provides.
Inclusions are normal in emeralds. The French word "jardin" (garden) describes them — they're not a defect, they're part of the stone's character and proof of its natural origin. An eye-clean emerald commands a significant premium precisely because it's so rare.
