Opal Oval Pendant Chain Necklace | 100100109318636

How to Measure Your Opal Oval Pendant Chain Necklace

1. Chain length:
   • Wrap a soft measuring tape (or a string you can later measure with a ruler) around your neck where the chain will sit.
   • Common lengths and where they fall on most necks:
     • 14 in / 35.5 cm — high choker
     • 16 in / 40.6 cm — base of neck
     • 18 in / 45.7 cm — at collarbone (most popular)
     • 20 in / 50.8 cm — just below collarbone
     • 22–24 in / 56–61 cm — upper bust
   • If there is an extender, measure the minimum and maximum (e.g., 16–18 in).
2. Pendant size (oval opal):
   • Height without bail: measure from the very top of the oval to the bottom (in mm).
   • Height with bail (overall drop): measure from the top of the bail loop to the bottom of the pendant.
   • Width: measure at the widest middle point of the oval (in mm).
   • Depth/thickness: measure from front dome to the back (in mm).
   • Tip: 1 inch = 25.4 mm. Jewelry dimensions are usually listed in millimeters.
3. Bail opening (to know which chains fit):
   • Measure the inner width and height of the bail opening in mm.
   • Choose a chain whose thickness is slightly smaller than the bail’s inner width.
4. Weight (optional):
   • Use a jewelry scale for total necklace weight or pendant-only weight (grams).
5. Clasp and extender:
   • Note clasp style (spring ring or lobster) and extender length if present.

Materials & What to Know

About Opal (the centerpiece)

• Opal is hydrated silica with natural “play‑of‑color.” Hardness is typically 5.5–6.5 on the Mohs scale.
• Types you may see for oval pendants:
  • Natural solid opal (e.g., Australian, Ethiopian): a single piece of opal; each stone is unique.
  • Hydrophane Ethiopian opal: can absorb water/oils; color may temporarily mute when wet and return as it dries.
  • Lab‑created opal: real opal grown in a lab; vibrant, consistent color; generally stable and budget‑friendly.
  • Opal doublet/triplet: a thin opal layer on a backing (doublet) and sometimes with a protective cap (triplet). Lightweight and vibrant; avoid prolonged soaking.
  • Opalite glass: an attractive glass look‑alike; typically shows a uniform milky/blue glow without true play‑of‑color.
• Settings:
  • Bezel (metal surrounds the stone) offers extra protection for the softer opal surface.
  • Prong settings maximize light but need a bit more care during wear and storage.

Metals & Chains

• 925 Sterling Silver: 92.5% silver, often rhodium‑plated to reduce tarnish; typically nickel‑free.
• Gold Vermeil: thick gold plating (≥2.5 microns) over sterling silver; richer color, better longevity than standard plating.
• Gold‑Filled: heat‑bonded layers of gold over a base; at least 5% gold by weight; very durable.
• Solid Gold (10k/14k/18k): fine, low‑maintenance, great for sensitive skin.
• Stainless Steel (316L): strong, corrosion‑resistant; PVD finishes hold color well.
• Brass base with plating: accessible price point; store dry and avoid friction to preserve finish.
• Common chains: cable/trace, box, curb, snake. Typical thickness: 1.0–2.5 mm. Ensure the bail opening fits your chain.

How to tell what you have

• Look for notes like “solid opal,” “lab‑created,” “doublet/triplet,” or “opalite.”
• Doublets/triplets often show a fine layer at the edge; avoid long soaks to protect the adhesive.
• Lab‑created opals can show very uniform patterning; natural stones vary more and may include inclusions or matrix.

Model & Fit Guide

• On most necks, 16 in sits at the base of the neck; 18 in sits at the collarbone; 20 in falls just below.
• Petite necks may find 16 in looks similar to an 18 in on broader necks. Measure your neck and add:
  • +0–1 in for a close fit/choker
  • +2 in for standard “at collarbone” look
  • +4 in for a lower, layered look
• Pendant drop reference: the “overall drop” is top of bail to bottom of pendant; this helps visualize where the opal sits on your chest relative to the chain length.
• If viewing on‑model photos, compare where the pendant sits to your own collarbone for an at‑a‑glance length match.

Care Guide (to keep it lovely longer)

• Last on, first off: put the necklace on after skincare, perfume, and hairspray; remove before workouts, swimming, or showering.
• Avoid ultrasonic or steam cleaners. Clean gently with a soft, slightly damp cloth; mild soap only if needed; dry well.
• For doublets/triplets: do not soak. Wipe only and keep water exposure brief.
• Hydrophane opals can absorb water and oils; color may mute temporarily when wet—allow to dry naturally away from heat.
• Keep away from extreme heat, sudden temperature changes, and harsh chemicals.
• Store separately in a soft pouch or box to prevent scratches; avoid crushing pressure on the opal dome.
• Silver: use an anti‑tarnish cloth on the metal only (avoid rubbing the opal). Avoid silver “dip” solutions on opal pieces.
• Plated/vermeil finishes: avoid abrasives and excessive friction to preserve the plating.

Style Tips

• Let the opal shine: pair with simple tees, silk blouses, or slip dresses in neutral tones to highlight the play‑of‑color.
• Layer thoughtfully: wear the oval pendant at 18 in and add a 14–16 in choker above or a 20–22 in chain below for depth.
• Match metals to mood: yellow gold warms the opal’s reds and oranges; white metals amplify blues and greens; rose gold adds a romantic glow.
• Keep earrings minimal—studs or small hoops—to keep focus on the pendant. For evening, add delicate stacking rings.
• Perfect gift: opal is October’s birthstone and symbolizes creativity and light—ideal for birthdays, anniversaries, or self‑treats.
• Neckline pairing: V‑necks and scoop necks mirror the pendant’s drop; turtlenecks pair well with 20–24 in lengths worn over knitwear.
