Vintage Blue Sandstone Pendant Copper Necklace | 100100944243570

How to Measure

1. Pendant height:
   • Measure the stone/setting only (without the top loop/bail) for visual size.
   • Measure again including the bail if you want the total drop length of the pendant.
2. Pendant width and thickness:
   • Measure the widest point side‑to‑side.
   • Measure thickness from front dome to back plate to know how it sits against the chest.
3. Bail/loop opening:
   • Measure the inner height and width of the bail to ensure your preferred chain or cord will fit.
4. Chain length:
   • Unclasp the chain, lay it flat, and measure end‑to‑end including clasp and ring.
   • Drop length on the body is roughly half the chain length, plus the pendant’s total height if you want where the bottom lands.
5. Finding your best length:
   • Wrap a string around your neck where you want the chain to sit, mark it, then measure the string.
   • Common lengths: 40 cm (16 in) choker, 45 cm (18 in) at collarbone, 50 cm (20 in) just below collarbone, 55–60 cm (22–24 in) upper bust.

Quick conversion: 1 in = 2.54 cm. All measurements are approximate and can vary slightly by handmade setting.

Materials & Composition

Blue Sandstone (also known as Blue Goldstone)

• Type: Man‑made glass with suspended metallic crystals that create a starry sparkle.
• Color: Deep midnight blue matrix; the glitter comes from tiny reflective inclusions (commonly copper microcrystals). Cobalt colorants are often used to achieve the blue tone.
• Feel & look: Smooth, highly polished surface with a uniform shimmer that mimics a night sky.
• Durability: Approx. 5.5–6 on the Mohs scale (similar to glass). Resistant to everyday wear but can chip if dropped or scratched by harder minerals.
• Care note: Avoid abrasive cleaners and hard impacts to preserve the glossy finish.

Copper (chain, setting, and findings)

• Appearance: Warm reddish‑gold tone that pairs beautifully with deep blue stones.
• Natural behavior: Copper develops a darker patina over time; this is normal and can be polished if a brighter look is preferred.
• Skin note: Copper may leave a temporary greenish mark on skin in humid conditions; it’s harmless and washes off.
• Allergy note: Copper itself is generally nickel‑free, but some clasps or components from mixed alloys may contain traces of other metals. If you have metal sensitivities, verify component composition before wear.
• Durability: Copper is relatively soft; avoid heavy pulls or sharp bends to keep links and settings in shape.

Model & Fit Guide

• Choker look (35–40 cm / 14–16 in): sits closely around the base of the neck.
• Classic/versatile (45 cm / 18 in): rests at the collarbone; a popular everyday length for most necklines.
• Below collarbone (50 cm / 20 in): slightly longer, great for layering.
• Statement drop (55–60 cm / 22–24 in): upper bust; ideal for high necklines or a dramatic pendant focus.
• Layering tip: Pair a shorter plain chain above and a longer simple chain below to frame the Blue Sandstone pendant without crowding it.
• Fit matching: To replicate any look you see on a model, measure from the base of your neck to where you want the top of the pendant to sit, then double that number to estimate chain length (add the pendant’s height if you’re targeting where the bottom lands).

Care Guide (to keep it lovely longer)

• Last on, first off: Put the necklace on after perfumes, lotions, and hairspray; remove before workouts, showers, or swimming.
• Keep it dry: Moisture accelerates copper patina; wipe gently with a soft, lint‑free cloth after each wear.
• Storage: Store in an anti‑tarnish pouch or closed box, away from humidity and direct sunlight. Keep separate from harder jewelry to prevent scratches on the stone.
• Routine cleaning: Use mild soap and lukewarm water on a soft cloth; rinse and dry thoroughly. Avoid soaking if the stone is glued into the setting.
• Polishing copper: Use a jewelry polishing cloth for light tarnish. For deeper tarnish, a quick lemon‑juice (or vinegar) and a pinch of salt solution can brighten copper; apply briefly, rinse well, and dry completely. Do not use abrasives that could scratch the stone or remove protective finishes.
• Avoid: Ultrasonic or steam cleaners, bleach, ammonia, strong solvents, and sudden temperature changes.
• Patina preference: If you like the aged look, simply skip bright polishing and just keep the piece clean and dry.

Style Tips

• Color pairing: The midnight blue sparkle pops against neutrals (black, cream, grey), denim, navy, and warm earth tones. Copper’s glow complements autumn palettes and rose‑gold accessories.
• Necklines: V‑neck and scoop show off the pendant; turtlenecks and high collars benefit from longer chain lengths for a striking focal point.
• Layering: Try a 40–42 cm delicate chain above and a 55–60 cm simple chain below to frame the pendant. Keep other pieces minimal so the sparkle stays center stage.
• Occasions: Subtle shimmer for daytime; catches light beautifully in evening settings and under soft indoor lighting.
• Match with: Copper or rose‑gold toned earrings and bangles. Mixed metals can work—anchor the look with at least two copper elements for cohesion.
