A reversible pendant with two distinct looks

The Black Obsidian Necklace - Hidden Heart is a double-sided design: one face is a sleek, polished black obsidian, and the reverse has a hidden heart cut-out. That single detail changes how you wear it. With the heart side outward, the obsidian rests gently on your skin, creating an intimate skin-to-gem connection. With the plain side outward, the necklace reads as a clean, minimal black pendant.

The catalog frames black obsidian as a protective shield that can relieve stress and foster inner strength. Whether or not you connect with that symbolism, the design gives you a practical choice: a discreet everyday piece or a more personal statement, depending on which way you turn it.

What the catalog confirms

  • Black Obsidian Necklace - Hidden Heart: Stone size: 0.35" x 0.24" (9mm x 6mm); stone weight: 1.57 ct; metal weight: 2.08–2.10 g. These dimensions tell you the pendant is small and light—closer to a subtle dot on the collarbone than a large statement piece.

  • Black Obsidian Necklace - Hidden Heart: Chain length: 16" with a 2" extender. The extender lets you wear it at 16", 17", or 18", so you can adjust where the pendant sits relative to your neckline.

  • Black Obsidian Necklace - Hidden Heart: Available in 18kt Yellow Gold Vermeil, 925 Sterling Silver, and 18kt Rose Gold Vermeil. Your metal choice changes the necklace's warmth and how easily it layers with pieces you already own.

  • Black Obsidian Necklace - Hidden Heart: Cut: pear-shaped brilliant cut; gem authenticity approved by GIA. The cut affects how the obsidian catches light, and the GIA approval confirms the stone's identity.

How to wear the Hidden Heart two ways

The necklace is designed to be turned, not just worn one way. Use these checkpoints to decide which side suits the moment.

  1. Heart side outward for a personal, skin-close look: The catalog says that when worn with the heart side outward, the obsidian rests gently on your skin. This orientation makes the heart cut-out visible and keeps the stone in direct contact with your skin—best for lower necklines or moments when you want the piece to feel intimate.
  2. Plain obsidian side outward for a clean, minimal finish: Turning the polished black face forward hides the heart and gives you a simple black pendant. This is the easier choice for high necklines, office wear, or when you want the necklace to blend rather than draw attention.
  3. Set the chain length before you turn the pendant: Use the 2" extender to find the right drop first. A shorter 16" setting keeps the pendant near the collarbone; extending toward 18" lowers it. Once the length is set, turn the pendant so the side you want faces out.

Choosing between gold vermeil, rose gold vermeil, and sterling silver

All three options use the same black obsidian stone and the same chain length. The difference is the metal finish and how it interacts with your skin tone and existing jewelry.

  • 18kt Yellow Gold Vermeil: A warm, classic finish that contrasts with the black stone. It suits warm skin tones and pairs naturally with yellow gold rings or earrings you already wear.
  • 18kt Rose Gold Vermeil: A softer, pink-toned metal that keeps the necklace feeling romantic. It works well if you prefer rose gold over yellow or white metals, or if you want the heart motif to feel more delicate.
  • 925 Sterling Silver: A cool, neutral finish that makes the black obsidian the focus. It is the most straightforward choice if you mostly wear silver-toned jewelry or want a high-contrast look.

Styling the pendant for everyday and evening

Because the pendant is small—9mm by 6mm—it works best as a quiet layer rather than a standalone centerpiece. The reversible design gives you two styling modes.

  • Everyday with a plain side out: Wear the polished obsidian face forward with a crew-neck tee, a button-down, or a fine-knit sweater. At 16" it sits close to the collarbone; extend it slightly if your neckline sits lower.
  • Evening with the heart side out: Turn the heart cut-out outward for a lower neckline or a dress. The skin-to-gem contact is part of the design's intention, so this orientation suits open necklines where the pendant can rest against your skin.
  • Layering with other chains: The 16"–18" range makes it easy to pair with a longer chain. Keep the Hidden Heart as the shortest layer so the small pendant stays visible, and choose a second chain with a different link style to avoid tangling.

What the catalog does not confirm

The supplied information does not state whether the black obsidian or the metal finishes are hypoallergenic, water-resistant, or suitable for sensitive skin. It also does not include specific care instructions for the stone or the vermeil and sterling silver surfaces. If you have metal sensitivities or need care guidance, treat those as open questions rather than assuming the necklace is suitable for every wearer.

The catalog also does not describe the clasp type or the chain style beyond its length. Those details are worth checking with the store if they matter to you.
