Tanzanite, Ruby and Diamond Pendant Necklace 14kt Yellow Gold

This Tanzanite, Ruby and Diamond Pendant Necklace combines a warm-toned natural tanzanite centrepiece with smaller blue-toned tanzanite accents, vibrant natural rubies, and natural diamonds, all set in 14kt yellow gold on an 18-inch 1.00mm solid box chain. The pendant measures 0.65 by 0.40 inches. The combination of warm-toned tanzanite centre with cool-toned tanzanite accents within the same piece is unusual, the design uses two different expressions of tanzanite's natural trichroism (warm/burgundy and cool/blue) within the same setting, producing a single piece that displays the full colour range of the gemstone.

About the Tanzanite, Ruby, and Diamond

The pendant combines four natural stone elements: a warm-toned tanzanite centrepiece (showing the burgundy axis of tanzanite's trichroism), smaller cool-toned tanzanite accents (showing the blue-violet axis), natural rubies (corundum, deep red), and natural round diamonds. All stones are natural mined gemstones. Using both warm and cool axes of tanzanite within the same piece is uncommon, most tanzanite jewelry commits to one tonal direction, this piece deliberately includes both to display the complete colour range of the species.

About the Setting and Chain

The 14kt yellow gold setting (585 purity) holds the warm-toned tanzanite centre with the smaller accent stones (tanzanite, ruby, diamond) prong-set around it. The 18-inch 1.00mm solid box chain is included, box chain is a recognised classical chain pattern with square link cross-sections that drape evenly and pair well with both small daily pendants and substantial statement pieces. Yellow gold reinforces the warm character of the centre tanzanite while the ruby accents add deeper colour depth.

Tanzanite's Trichroism in Mixed-Stone Pieces

Tanzanite displays three colours depending on viewing angle, blue, violet, and burgundy/warm-toned. Most tanzanite jewelry commits to one axis (typically the blue-violet, achieved through cool metal settings and specific cut orientations). This pendant is unusual because it deliberately uses two tanzanite expressions in one piece: a warm-toned centre and cool-toned accents, with ruby and diamond rounding out the colour palette. The result reads as a single multi-stone composition rather than a tanzanite-only piece, well-suited for buyers who want a coloured-stone necklace with depth across multiple gemstone categories rather than a single-stone tanzanite minimalist piece.

Frequently Asked Questions

Are all the stones natural?

Yes. The centre tanzanite, the smaller tanzanite accents, the rubies, and the diamond accents are all natural mined gemstones.

Why does the centre tanzanite look brown but the smaller tanzanite stones look blue?

Tanzanite is trichroic, the same species displays three colours (blue, violet, burgundy) depending on cut orientation and viewing angle. The centre stone in this pendant is cut and set to emphasise the warm/burgundy axis. The smaller accent tanzanites are cut to display the cool blue-violet axis. Both are genuinely tanzanite, the difference is which trichroic axis is emphasised. Including both expressions in the same piece is intentional design.

Is the chain included?

Yes. The 18-inch 1.00mm solid box chain in 14kt yellow gold is included.

Is the gold real 14kt yellow gold?

Yes. The setting and chain are real 14kt yellow gold (purity 585).
