The Stone of Transformation

Tanzanite is the blue-to-violet variety of zoisite, discovered only in 1967 and found in a single area of the world. Its strong pleochroism means it can show different colours — blue, violet, burgundy — depending on the viewing angle, before cutting.

Gemologically, tanzanite is described as transparent, with a vitreous luster — qualities that shape how it catches and carries light once cut. Its colour comes from vanadium, with colour enhanced by heat treatment, and a Mohs hardness in this range calls for a little extra care — pendants, earrings, and occasional-wear rings suit it better than an everyday ring.

The "Heart of the Ocean" Look

Tanzanite's deep, oceanic blue-violet has made it a favourite choice for the dramatic heart-shaped pendant style popularised by the famous "Heart of the Ocean" necklace from the 1997 film Titanic — itself inspired by the real Hope Diamond, and created for the film as a large blue stone set within a diamond surround on a sweeping necklace. While the original film piece was a blue diamond design rather than tanzanite, the silhouette — a bold, heart-cut blue-violet centre stone framed by diamonds or pavé — has become one of the most requested styles for tanzanite, whose colour and brilliance lend themselves beautifully to this kind of statement design at a far more accessible price point than a diamond of comparable size and colour.

Crafted Exclusively in Jaipur

Every tanzanite piece in the Paraiso Jewels collection is cut, set, and finished in Jaipur — drawing on Rajasthan's centuries-old tradition of coloured-stone craftsmanship. From rough stone to finished setting, our tanzanite jewellery does not pass through any other production centre, giving us direct oversight of cutting quality, setting work, and finishing at every stage.

Where Tanzanite Comes From

Folklore and Healing Traditions

Tanzanite has held a place in decorative arts, folklore, and crystal-healing traditions across cultures for centuries. Those drawn to this dimension of the stone often choose it for its colour and character as much as for any tradition attached to it — a personal, rather than prescriptive, choice.

How Tanzanite Is Graded

Quality in tanzanite is generally assessed across colour, clarity, cut, and carat weight — with colour and overall character typically the dominant factors in value.

What a Lab Report Confirms

A lab report identifies the species, describes colour, and discloses any treatment. Virtually all tanzanite is heat-treated to remove brownish tones and bring out its signature blue-violet colour — a standard, accepted, and permanent process.

Natural, Ethical, Jaipur-Sourced

Every tanzanite in the Paraiso Jewels vault is described accurately as to its natural or treated status on its label. We source through Jaipur's gem market — one of the world's oldest and most concentrated coloured-stone trading centres — and our stones can be verified at GTL Jaipur, the region's principal gem testing authority.

On request, each piece can be accompanied by documentation covering weight, dimensions, and treatment status. If you have questions about the origin or treatment of a specific stone, contact us via WhatsApp or email and we'll provide full details.
