The October Birthstone
Opal is the October birthstone, prized for its play-of-color: the shifting rainbow flashes that make every stone one of a kind. Long associated with hope, creativity, and inspiration, it makes this necklace a meaningful gift for anyone born in October, or anyone who loves a little everyday sparkle.

Care
Opals are softer than most gemstones and can be sensitive to water and chemicals. Store in a dry place, away from harder jewelry. Remove before swimming, showering, workouts, or applying lotions and perfumes, and take it off at night. Wipe gently with a soft cloth to maintain shine.
This step-by-step jewelry sizing guide shows you exactly how to measure for the perfect fit, without guessing. It's a tried-and-true method used by stylists, jewelers, and minimalist jewelry lovers everywhere. Before we begin, I’ll show you a rough necklace length guide on a model so you have an idea of how the different lengths will look. Please note that everyone is unique in their sizing so it is important to follow the measuring guide if you are looking for a perfect length unique to you.

What You’ll Need to Measure
Before you begin, gather:
-
A piece of thread, string, or thin ribbon
-
A ruler or measuring tape
-
A mirror (optional, for checking placement)
Step-by-Step: How to Measure Necklace or Bracelet Size
1. Wrap the String
-
For necklaces: Loop the string around your neck to where you'd like the pendant or chain to sit—collarbone, chest, or longer.
-
For bracelets: Wrap around your wrist where you'd like the bracelet to rest—snug or slightly loose.
2. Mark the Length
-
Pinch or cut the string at the exact point where both ends meet.
-
This marks your ideal jewelry length.
3. Measure the String
-
Lay it flat against a ruler or tape measure.
-
Write down the measurement in inches—this is the size to order.
Pro Tip: If you're between sizes, go up a half an inch for comfort.
