Natural Gemstones

Every Stone Is One of a Kind

Jewelry by Crimson works with natural gemstones. Because each stone is formed by nature, small variations in color, tone, inclusions and character are normal and are part of what makes your piece unique. The stone you receive may differ slightly from the photographs, which are taken under studio lighting.

Gemstone details for this piece are listed exactly as recorded for this listing:

Stone: Type: Treatment: Origin:

Where a treatment or origin is not shown, it has not been recorded for this item. We never claim “untreated” or a specific origin unless it is stated for the individual piece.

From Gemstone to Jewelry

Our Craftsmanship

Jewelry by Crimson is the jewelry brand of Crimson Gems Co., Ltd., a Bangkok-based gemstone and jewelry company established in 2011. The same team that sources and cuts our gemstones also designs and produces the finished jewelry — so every piece is made under one roof, from stone to setting.

Gemstone cutting and polishing

Thailand’s gemstone heritage, in-house

Thailand is one of the world’s great centers for colored gemstones, and Crimson Gems has been part of that trade for more than a decade. Our stones are selected and cut by our own team, with a sourcing connection to Chanthaburi — Thailand’s historic gem-cutting province — and our head office at the Jewelry Trade Center on Silom Road, Bangkok.

Because we handle the gemstones ourselves, we control quality, matching and consistency at every stage, and we can offer natural gemstone jewelry at prices that reflect a maker, not a middleman.

Sizing Guide

Ring sizing

Ring sizes are shown in US sizing. The most reliable way to check your size is to measure the inside diameter of a ring that already fits the intended finger, then compare it with the table below.

US size 5 5.5 6 6.5 7 7.5 8 8.5 9 10
Inside diameter (mm) 15.7 16.1 16.5 16.9 17.3 17.7 18.1 18.5 19.0 19.8
Circumference (mm) 49.3 50.6 51.9 53.1 54.4 55.7 57.0 58.3 59.5 62.1

If this listing states that the ring can be sized, choose your size when ordering or message us before purchase. Fingers change size with temperature and time of day — measure when your hands are at normal temperature.

Necklace & pendant length

The length shown in the details is the chain length. Use this guide to picture where it will sit:

Length 40 cm / 16 in 45 cm / 18 in 50 cm / 20 in 60 cm / 24 in
Sits at Base of the neck Collarbone (most popular) Just below the collarbone Upper chest

Tip: measure a necklace you already wear and love, or wrap a soft tape around your neck at the point where you want the chain to sit.

Bracelet & bangle sizing

  • Bracelets: wrap a soft measuring tape (or a strip of paper) snugly around your wrist just above the wrist bone and note the measurement. Add about 1–2 cm (½–¾ in) for a comfortable fit, then compare with the length shown in the details.
  • Bangles: bring your thumb and little finger together to make your hand as narrow as possible, then measure around the widest part of your hand. This is the smallest inner circumference a bangle needs to slide over.

If you are between sizes, choose the larger one for a relaxed fit or the smaller one for a snug fit. Message us if you would like help choosing.

Earring size

The overall drop or diameter is shown in the details above. Studs and huggies sit close to the ear; drop and dangle earrings hang below the lobe by the length shown.

Looking after your piece

Jewelry Care

925 sterling silver

  • Wipe gently with a soft, dry cloth after wearing.
  • Sterling silver naturally tarnishes over time — a silver polishing cloth restores its shine.
  • Store in the box or a sealed pouch, away from humidity.

Gold-plated & vermeil

  • Put your jewelry on last, after perfume, lotion and hairspray.
  • Remove before showering, swimming, exercising or sleeping.
  • Avoid abrasive polishing cloths and chemical dips, which can wear the gold layer.

Natural gemstones

  • Clean with lukewarm water, a drop of mild soap and a soft brush; dry thoroughly.
  • Avoid ultrasonic cleaners, steam, harsh chemicals and sudden temperature changes.
  • Store pieces separately so stones do not scratch each other.
