Trillion Tanzanite and Diamond Ring 0.41tcw 14kt Yellow Gold

This Trillion Tanzanite and Diamond Ring features a 0.32ct trillion-cut natural tanzanite paired with 0.09ct of G/H natural diamond accents, set in 14kt yellow gold for a total weight of 0.41 carats. The trillion cut, a triangular shape with curved or pointed sides, is one of the more distinctive geometric cuts for tanzanite, producing visual angles that catch light differently from oval, pear, or round cuts. Yellow gold is an unconventional metal choice for tanzanite (white gold is more common), the warm metal tone interacts with tanzanite's burgundy axis rather than amplifying the blue, producing a richer, warmer overall presentation.

About the Tanzanite

The 0.32ct centre stone is a natural mined tanzanite from the Merelani Hills of Tanzania, the only commercial tanzanite source on earth. Tanzanite is famously trichroic, the same stone displays blue, violet, and burgundy components depending on viewing angle. In a yellow gold setting like this one, the warm metal tone supports the violet and burgundy axes of tanzanite's trichroism rather than emphasising the blue, producing a softer overall colour presentation than the same stone would show in white gold. Tanzanite registers 6.5 to 7 on the Mohs hardness scale.

About the Trillion Cut and Setting

The trillion cut is a triangular gemstone shape with three roughly equal sides, sometimes with curved sides (modified trillion) or sharp points (true trillion). Trillion-cut tanzanites are less common than oval, pear, or round cuts, the cut is harder to execute well in coloured stones because the geometry must align with the stone's natural pleochroism axes. The 14kt yellow gold setting (585 purity) holds the trillion centre with diamond accents along the shoulders. Yellow gold for tanzanite is a deliberate aesthetic choice, see our companion 1.09tcw Trillion Tanzanite Ring (AJDGR-0076) for a larger version of this same design at a higher carat weight.

Same design language, same metal, same trichroic stone, the difference is centre stone scale.

Frequently Asked Questions

Is the tanzanite natural?

Yes. The 0.32ct trillion centre is a natural mined tanzanite from Tanzania. Like virtually all commercial tanzanite, the stone is heat-treated to bring out the colour from the raw brownish material, this is a standard accepted trade practice and not a colour-altering chemical process.

How does this compare to the 1.09tcw Trillion Tanzanite Ring?

Both rings are trillion-cut natural tanzanite in 14kt yellow gold with diamond accents. This 0.41tcw piece has a smaller 0.32ct centre at $1,220. The 1.09tcw version (AJDGR-0076) has a larger 0.93ct centre at $1,750. Same design family, the difference is centre stone size.

Why yellow gold for tanzanite when white gold is more common?

Yellow gold is a deliberate aesthetic choice for tanzanite. White gold's cool tone amplifies tanzanite's blue axis, producing the classic blue-violet appearance most associated with the stone. Yellow gold's warm tone supports tanzanite's violet and burgundy axes, producing a softer, warmer overall colour presentation. Both are gemologically valid, the choice is buyer preference.

Is tanzanite durable for daily ring wear?

Tanzanite registers 6.5-7 on the Mohs hardness scale, suitable for ring wear with basic awareness: avoid hard impact, ultrasonic cleaners, and steam cleaning. Smaller centre stones (like the 0.32ct in this ring) are also less exposed than larger statement stones, which makes daily wear comfortable for most buyers.

Is this a December birthstone ring?

Yes. Tanzanite is one of three modern December birthstones (alongside turquoise and zircon), officially added to the American Gem Trade Association list in 2002.
