✦ SIZING & CARE MASTERCLASS

The Complete Sizing & Care Guide

Household Tools You Can Use:

You don’t need professional jeweler tools to find your perfect fit. A standard strip of paper, dental floss, sewing tape, or an ordinary ruler (or smartphone measurement app) is all you need.

Finding Your Ring Size

Measurement method & international conversion matrix

Your ring should slide on smoothly and offer slight resistance when coming back over the knuckle. Because temperatures can cause your fingers to slightly contract in the cold and expand in warmth, measure your hands at room temperature toward the end of the day.

01

Wrap & Snug

Cut a thin paper strip (about 1 cm wide) or piece of non-stretchy string. Wrap it around the base of the finger you plan to wear the ring on.

02

Mark the Overlap

Pull the paper snug (not too tight). Use a pen to mark the exact point where the paper meets the starting edge.

03

Measure in Millimeters

Lay the paper flat against a metric ruler. Measure the length from the start to your pen mark in millimeters ($mm$) to find your circumference.

04

Check Existing Ring

Already own a ring that fits? Place it flat on a ruler and measure the inside diameter ($mm$) from inner edge to inner edge.

Measuring Your Wrist & Bracelets

How to select your preferred drape and fit

Every Luminellic bracelet arrives with an integrated **2-inch extender chain**, giving you flexible room to loosen or tighten the fit on the fly.

  • Step 1 (Base Measurement): Wrap a flexible sewing tape or string around your wrist bone, exactly where you prefer wearing your jewelry.
  • Step 2 (Record Base Size): Note the exact number without pulling too tight (e.g., 6.0 inches / 15 cm).
  • Step 3 (Choose Your Fit Style):
    • Snug / Tailored Fit: Add 0.5 inches (1.2 cm) to your base measurement.
    • Comfort Drape (Recommended): Add 0.75 - 1.0 inch (2.0 - 2.5 cm) to your base measurement.
    • Loose Bangle Fit: Add 1.25 - 1.5 inches (3.0 - 3.8 cm) to your base measurement.

Necklace Drape & Layering

Visual chest placement guide

Choosing the ideal chain length depends on your collarbone structure, neckline, and whether you are wearing a single pendant or creating a cascading layered look.

14" - 16" (35 - 40 cm)

Choker & Collarbone

Wraps closely around the throat base or rests along the collarbone. Ideal for open-neck tops, crew necks, and minimalist base layering.

18" (45 cm)

Princess (Most Popular)

The universal standard. Falls softly just below the collarbone, pairing effortlessly with plunging necklines, tees, and blouses.

20" - 24" (50 - 60 cm)

Matinee & Opera

Extends toward the middle of the chest. Highlights larger pendants, lockets, and complements turtlenecks and layered sweaters.

💡
At-Home String Technique for Necklaces:

Cut a piece of thread or dental floss to your desired length (e.g. 18 inches), loop it around your neck, and check where it rests in a mirror to confirm your preferred placement before ordering.


Anklet Sizing

Measurement guide for ankle jewelry

Anklets look best when they sit loosely just below the ankle bone so they move naturally with every step.

  • How to Measure: Measure your ankle with a tape just above or right below the ankle bone where you want the piece to sit.
  • Comfort Allowance: Add 0.75" to 1.0" (2.0 to 2.5 cm) to your base ankle measurement.
  • Standard Size: Our anklets are crafted at an **8.5-inch base with a 2-inch extender**, comfortably fitting ankles from 8.5" to 10.5" (21.5 cm to 26.5 cm).
