The Emerald-Cut Precious Stone Tennis Necklace sets a line of diamonds the whole way round in solid 18K gold, with a oval-cut ruby, blue sapphire or emerald at the centre — the coloured twin of our oval-Cut Diamond Tennis Necklace, made by our own atelier.
The emerald is claw-set slightly above the line, so its colour stands out against the white of the diamonds, and the necklace turns freely with no plain section at the back. A ruby, sapphire or emerald heart tennis necklace, with natural or lab-grown diamonds.
Available with natural or lab-grown diamonds. Natural diamonds come in 38, 40 or 42 cm; lab-grown diamonds are made in 38 cm only.

The Turquoise Constellation Sautoir spaces small turquoise beads along a delicate 18K gold chain worn at sautoir length. Approx. 2.3 ct of turquoise on 5.6 g of solid 18K gold (750 hallmark), in yellow, rose or white gold, with a certificate of authenticity.
The beads are set at intervals rather than strung continuously, so the turquoise reads as a line of separate points of colour with the chain visible between them. Worn full length at 95 cm it falls below the bust; doubled at the neck it becomes a necklace of about 47 cm, and the spacing then reads twice over on the same neckline. It closes on an 18K gold clasp with three openings. No diamonds are set. The same sautoir is also made with coral beads.

A vertical line of multicoloured precious stones running from wrist to finger — approx. 1.50 ct in total on approx. 4.8 g of solid 18K gold (750 hallmark), available in yellow, rose or white gold, with a certificate of authenticity.
1.50 ct is the heaviest stone setting of the hand chains, and running the colours in a single line along the back of the hand is what makes the piece read as one design rather than as a bracelet and a ring joined together. No diamonds are set — the colour carries it. The 18K gold clasp has three openings, giving 15.5 cm, 16.5 cm or 17.5 cm at the wrist.

The Bezel Gemstone Eternity Band – Chromia sets bezel-set coloured gemstones the full way round with a brilliant white diamond among them, on approx. 3.2 g of solid 18K gold (750 hallmark), in yellow, rose or white gold, with a certificate of authenticity.
Four and a half carats of coloured stone on only 3.2 g of gold — among the highest stone-to-metal ratios of any ring in the range. Bezel settings enclose each stone in its own rim, which is what allows so much colour to sit round a band this slender without claws catching. Set the full circumference, so it reads the same from every angle.

The Pure Heart Precious Stone necklace hangs a single heart-cut precious stone from a fine 18K gold chain, with nothing else on the chain to compete with it. The stone is chosen at order in emerald, ruby or sapphire. Solid 18K gold (750 hallmark), in yellow, rose or white gold, with a certificate of authenticity.
A heart cut is symmetrical, so it hangs level rather than tipping the way a pear or a marquise does. Light enough for every day and easy to layer under a longer chain. The same heart is made with a white diamond centre in the Pure Heart necklace.

The Romeo Rhodium Ring sets an emerald-cut centre stone among vibrant green gemstones with black rhodium accents, on approx. 6.2 g of solid 18K gold (750 hallmark), in yellow, rose or white gold, or with a black rhodium finish, with a certificate of authenticity.
Rhodium is plated over the gold to darken it, which throws the green stones forward instead of letting warm gold compete with them. At 1.74 ct the centre is by far the largest of the three Romeo rings.
