Description
Inspired by sandhya, the hour of dusk over the Ganga when the sky slips from soft green-gold into rose, the Sandhya Bi-Colour Tourmaline & Diamond Necklace holds that shifting light in three natural stones.
Three faceted tourmalines are suspended one below the other, each showing its own gentle blend of mint green, peach and dusky rose. The upper two are framed in diamond-set borders with softly pointed corners, and the drop ends in a pear-shaped tourmaline that fades from green into warm pink, finished with a fine diamond edge. The pendant hangs from a delicate gold chain.
Rare yet wearable, this tourmaline necklace brings together natural gemstones, diamonds and contemporary fine jewellery design. Because every bi-colour tourmaline is unique, no two pieces carry quite the same colour story. Wear it with an open neckline for an evening, or let it anchor a simple, pared-back look.

Know Your Diamond
Understand the 4Cs of your diamond — cut, colour, clarity and carat — and see how this piece is graded.

Cut
The most important C
Cut is the most important factor in a diamond's brilliance. Expertly proportioned facets allow light to reflect beautifully, creating exceptional fire and sparkle. A well-cut diamond appears brighter, livelier, and more radiant from every angle.

Colour
Near colourless, naturally beautiful
Diamond colour is graded D (completely colourless) to Z (light yellow). The closer to D, the rarer and more valuable. Our EF-grade diamonds sit at the very top of the scale — virtually colourless to the naked eye, with a pure icy white appearance.

Clarity
Nature's fingerprint
Clarity measures internal inclusions and surface blemishes, graded from Flawless to I3. VVS (Very Very Slightly Included) means inclusions are so minute they're invisible even under 10× magnification. To the naked eye, VVS diamonds appear perfectly clean.
VVS (Very Very Slightly Included) means inclusions are so minute they're invisible even under 10× magnification.

Carat
Weight, not size
Carat is the unit of diamond weight — one carat equals 0.2 grams. The weight shown here is the total across every diamond in the piece. When diamonds are spread across a design, each stone is smaller, but the combined weight delivers exceptional sparkle from every angle.
