Graduated diamond riviera necklace in solid yellow gold — NJewellery

Gold with Diamonds Fine Jewellery

Solid 9ct and 18ct gold diamond jewellery — natural and lab-grown. Tennis bracelets, studs, hoops, pendants and necklaces, made to order in Australia.

Gold with diamonds — solid 9ct and 18ct gold set with natural and lab-grown diamonds, made to order in Australia. This collection holds diamond tennis bracelets, stud and hoop earrings, station and riviera necklaces, solitaire pendants, diamond-set rings, bangles and charms, in yellow and white gold. Nothing here is plated, filled or bonded.

The natural-diamond pieces are made from 100% certified Australian gold and graded GH/SI or F/VS. The lab-grown pieces are certified E colour, VS clarity — the same stone chemically and optically as a mined diamond, grown rather than dug, which is why the same budget buys considerably more carat weight. Every piece is a special order, generally dispatched within a week.

Frequently asked questions

What is a diamond tennis bracelet?

A diamond tennis bracelet is a continuous line of similarly sized diamonds set all the way around the wrist, each stone held in its own setting so the bracelet stays flexible. NJewellery's tennis bracelets run from a 38-diamond everyday line to a 42-stone emerald-cut piece, in solid 9ct and 18ct yellow or white gold.

Is this jewellery solid gold or gold plated?

It is solid gold throughout — never plated, filled or bonded. Every piece is cast in solid 9ct or 18ct gold, in yellow or white, and hallmarked accordingly. The natural-diamond pieces are made from 100% certified Australian gold.

What is the difference between natural and lab-grown diamonds?

A lab-grown diamond is chemically, physically and optically identical to a mined diamond — it is grown in a laboratory rather than extracted from the ground, and it tests as diamond. The practical difference is price: NJewellery's lab-grown range is certified E colour and VS clarity, so the same budget buys substantially more carat weight than an equivalent natural stone. Natural stones in this collection are graded GH/SI or F/VS.

What do diamond grades like GH/SI, F/VS and E/VS mean?

The first letters are colour and the second are clarity. E and F are colourless, GH is near-colourless and looks white to the eye. VS means very slightly included and SI means slightly included — neither is visible without magnification. F/VS is the higher specification and costs more; GH/SI puts the budget into carat weight instead.

Should I choose 9ct or 18ct gold?

18ct gold is 75% pure gold, richer in colour and heavier, and costs more. 9ct gold is 37.5% pure gold, harder-wearing and more affordable. Both are solid gold and both are hallmarked. Most designs in this collection are offered in both.

Should I choose yellow or white gold?

Yellow gold warms a diamond and reads traditional. White gold makes a stone look brighter and cooler, and stacks well with silver. Most designs here are made in both, and each product page lets you pick.

How long does an order take?

These are special-order pieces, made for you rather than held in stock. Allow approximately one week before dispatch. If you need a piece for a specific date, say so when you order and NJewellery will confirm.

Where is this jewellery made?

NJewellery is an Australian jeweller based on the Central Coast of New South Wales. The natural-diamond pieces in this collection are made from 100% certified Australian gold.
