Investment-Grade Square 54 Carat Tanzanite and Diamond Pendant Necklace

Sale price$42,000.00 USD Regular price$65,000.00 USD
Status: In Stock

At 54.72 carats, this is a quintessential investment-grade tanzanite—the kind of gemstone even experienced collectors may wait years to encounter.

Its colour is extraordinary: a deep, velvety royal blue of exceptional saturation, illuminated by vivid flashes of violet as the stone moves through the light. The square-edged cushion cut gives the gem a powerful, architectural presence, while its flawless clarity allows light to travel freely through the stone, producing exceptional brilliance and an almost endless depth of colour.

Large tanzanites frequently sacrifice either colour or clarity as their size increases. This remarkable gemstone does neither. It combines monumental scale with the richest blue colour, exceptional purity and a lively, sparkling character—an exceedingly rare convergence in a tanzanite weighing more than 50 carats.

Striking yet refined, this is a true collector’s gemstone and the unquestionable heart of the necklace.

Beautifully crafted in luxurious 18 carat gold, this investment-grade tanzanite pendant has impressive scale while remaining remarkably elegant and wearable for a jewel of such substantial carat weight.

The design has been deliberately kept refined and understated. Every element has been chosen to enhance the exceptional center stone, allowing the 54.72 carat tanzanite to remain the unquestionable focus.

This necklace may be exhibited at international gem and jewelry trade shows and may not always be held at our usual stock location. Please contact us before purchasing to confirm availability and request current photographs or candid videos of the necklace.
