Bold Contrast Meets Modern Minimalism

The Ocean Depths is an apatite necklace that captures the drama of deep water — vivid, dark, and endlessly compelling. Three hand-selected natural stones play off each other in perfect contrast: vibrant blue-green apatite that shifts in the light, deep lustrous black spinel, and cool polished hematite. This apatite necklace is for those who want their jewelry to make a statement without saying a word.

Apatite is a rare gemstone with a colour range that rivals paraiba tourmaline — its blue-green hue has an almost electric quality that catches the eye from across a room. Paired with the depth of black spinel and the metallic cool of hematite, this blue green necklace creates a composition that is bold, modern, and deliberately striking. It sits at 44 cm with a 2.5 cm extender and pairs beautifully with pieces from our handcrafted necklace collection.

The Ocean Depths necklace features:

  • Apatite — rare blue-green gemstone, vivid electric colour, hand-selected
  • Black spinel — deep natural black, brilliant lustrous facets
  • Hematite — polished metallic silver, grounding cool accent
  • Length: 44 cm + 2.5 cm extender chain (total 46.5 cm)
  • Weight: 19g — substantial feel, quality presence

For a complementary bold look, pair this apatite necklace with our Black Heart Necklace — both share black spinel and rhodium silver for a cohesive layered style.

Rare Gemstones with Exceptional Lustre

This apatite necklace features three stones chosen for their exceptional individual character. Apatite is named after the Greek word for deception — it was historically mistaken for more expensive gems like tourmaline and peridot due to its vivid colour range. The blue-green variety used here has an almost neon quality that varies subtly between stones. Black spinel provides deep contrast and brilliant faceting. Hematite — an iron oxide mineral — brings a polished metallic tone that anchors the composition.

At 19g, the Ocean Depths has a pleasantly weighty feel that reflects the quality of its materials. All metal fittings are rhodium-plated — hypoallergenic, tarnish-resistant, and cool-toned to match the colour story of this natural stone necklace perfectly.

Materials at a glance:

  • Natural apatite — rare blue-green, hand-selected for vivid colour

  • Secure lobster clasp with 2.5 cm extender chain
  • Eco-friendly gift packaging included

Frequently Asked Questions

Q: What is apatite and why is it special?

Apatite is a rare natural gemstone prized for its vivid blue-green colour — a range that rivals paraiba tourmaline and has historically caused it to be mistaken for more expensive gems. The name comes from the Greek word for “deception.” Each apatite bead in this necklace is hand-selected for its colour intensity and natural character, making every piece genuinely unique.

Q: What are the 3 stones in this necklace?

The Ocean Depths combines apatite (vivid blue-green), black spinel (deep lustrous black), and hematite (polished metallic silver). Each stone was chosen specifically for the contrast it creates — the vivid colour of the apatite, the depth of the spinel, and the cool metallic grounding of the hematite work together to create a striking composition.

Q: What is the length of this necklace?

The Ocean Depths measures 44 cm with a 2.5 cm extender chain, giving a wearable range of 44–46.5 cm. This princess length sits just below the collarbone and suits most necklines. Note that this necklace has a shorter extender than most in our collection — the 2.5 cm allows for fine-tuning of fit rather than dramatic length changes.

Q: Are the fittings hypoallergenic?

Yes. All metal components use rhodium-plated silver color fittings, which are hypoallergenic and safe for sensitive skin. The cool-toned rhodium plating complements the blue-black colour story of this apatite necklace perfectly.

Q: Is this a good gift?

The Ocean Depths is a distinctive gift choice — its rare apatite stone and bold blue-black combination appeal to those who appreciate genuinely unusual jewelry. It arrives in premium eco-friendly packaging, ready to give. Full shipping details on our shipping page.
