Metal

Rose Gold

An alloy of gold and copper, Rose Gold is recognisable for its warm, peach-toned hue that complements a vast range of skin tones and designs. An uniquely coloured metal, existing somewhere between white gold’s stark brilliance and yellow gold’s classicism, Rose Gold is a romantic option for engagement and ceremonial styles.
The Rose Gold used for our creations is 70 per cent is recycled Australian gold, with 30 per cent newly mined. Of the latter, 86 per cent is confirmed Australian mined, the remaining being blended (used for clasps, earring backs, findings etc).
Metal

White Gold

With its bright, silvery-white, lustrous surface, White Gold is a cherished metal for jewellery and other keepsakes. Created by combining pure gold with other metals, its modern and sophisticated expression wears beautifully across different skin tones.
70 per cent of the gold that we use is recycled Australian gold, with 30 per cent newly mined. Our White Gold is rhodium plated – an industry-standard process whereby the natural colour of the metal is plated in a thin layer of rhodium (a naturally white metal), to evoke a luxurious hue that is consistent no matter the carat, and is reapplied annually.
Metal

Yellow Gold

A classic and timeless metal, yellow gold is revered for its rich, vibrant hue. Courtesy of its warm and luxurious appearance, many cultures historically imagined gold to represent the sun, and its durability makes it a preferred material for ceremonial pieces.
70 per cent of the gold that we use in our creations is recycled Australian gold, with just 30 per cent newly mined. Of the latter figure, 86 per cent is confirmed as Australian mined, and the remaining 14 per cent is blended. We harness this blended portion predominantly for our clasps, earring backs and findings.

Australian Blue Sapphire

COLOUR: Rich, Dark Blue REPRESENTS: Truth, Nobility & Faithfulness MOHS HARDNESS: 9
September’s birthstone, Sapphire, is one of the world’s most popular gemstones; sought out for its signature blue hue (though it can be found in other colors such as pink, yellow, and green). A variety of the mineral corundum, Sapphire’s extreme durability (second only to diamonds) makes it a long-lasting gemstone believed to promote wisdom, truth, and spiritual insight. Symbolising nobility and faithfulness, Sapphires have been historically favoured by royalty, and Australian blue Sapphires, used throughout Natalie Marie Jewellery collections, are known for their markedly darker, dramatic tone.
Stone

Black Spinel

COLOUR: Black REPRESENTS: Protection MOHS HARDNESS: 8 Black Spinel is a shiny, opaque gemstone, composed of magnesium-aluminum oxide and believed to promote grounding and protection – making it a popular inclusion for energy work and spiritual practices. Black Spinel is traditionally black or dark brown in colour, although it can also be found in shades of grey, blue, and green and is a popular substitute for black diamonds due to its mirrored appearance. It is historically credited with repelling negative energy; those that wear it are safeguarded from anger, sadness, and bitterness. Concurrently, they feel empowered and inspired, at peace in mind and body.
Stone

Laboratory Grown Diamond

COLOUR: White REPRESENTS: Inner Strength, Clarity & Everlasting Love MOHS HARDNESS: 10
A mindful and aesthetically brilliant alternative to their natural counterparts, Laboratory Grown Diamonds are grown in carefully controlled lab environments to evoke the same physical, chemical, and optical properties as mined diamonds. Renowned for their brilliance, fire, and durability, Laboratory Grown Diamonds are celebrated as the stone of love, embodying everlasting affection, friendship, purity and inner strength.
Stone

Morganite

COLOUR: Pink REPRESENTS: Love, Compassion & Healing MOHS HARDNESS: 8 Morganite is a pink to peach-coloured variety of the mineral beryl (which also includes emerald and aquamarine), first discovered in Madagascar in 1910 and named after the financier and gem enthusiast J.P. Morgan. Morganite’s shade is credited to the manganese present during its formation, and it is often cut into faceted shapes to enhance its brilliance and effervescence. The stone is believed to promote love, compassion, and healing, and its beauty is inherent in the unique nature of each stone. As hues vary between pieces, we recommend contacting our team to discuss your preference once you have placed your order.
Stone

Rutilated Quartz

COLOUR: Gold MOHS HARDNESS: 7.5 Rutilated Quartz is a fascinating variety of quartz that contains needle-like inclusions of the mineral rutile, which create dreamlike patterns within the quartz, ranging from delicate golden threads to thicker strands. Our stones are natural and untreated – we find beauty in their untouched imperfection – and their shade varies from piece to piece. For those with a specific preference for their Rutilated Quartz shade, please contact our team once your have placed your order.

Tourmalinated Quartz

COLOUR: Clear with Black Inclusions REPRESENTS: Inner Strength, Clarity & Everlasting Love MOHS HARDNESS: 7
Tourmalinated Quartz is unique and beautiful variety of quartz that contains needle-like inclusions of the mineral black tourmaline. The stone’s inclusions create detailed patterns within the quartz, ranging from delicate black threads to thicker strands.

GUIDE

All about metal Carat

Without delving too deep into the science of metals and alloys, our bespoke team have explained the differences to help you make the best choice for your next NMJ piece, and also shared with us whether there is a noticeable difference in colour between the carats.

FAQs

The difference between 9ct, 14ct and 18ct gold is the precious metal content. 9ct gold contains 37.5% pure gold, 14ct contains 58.5% pure gold and 18ct gold contains 75% pure gold. The remainder is a mix of various metals, depending on whether it is a yellow, rose or white gold piece.

In general, 18ct gold is the longer lasting, more durable choice, however 9ct gold can still be a great option for some Jewellery pieces. 9ct gold is commonly used for fine pieces of jewellery that are typically designed for casual wear. Our seasonal collection fashion pieces, or statement pieces are typically crafted in 9ct gold. The reason for this is that these are generally our finest pieces, and where 18ct is flexible, 9ct gold is more rigid and holds its shape better as it has the lowest pure gold content – making it great for casual wear while also bringing it into a more accessible price point. At NMJ, we always recommend 18ct gold for all precious pieces such as engagement rings and wedding bands.

Put simply, the higher the gold content, the richer the colour and warmer the tone, particularly for yellow and rose gold. However, only when side-by-side are these differences really noticeable to the eye, and they are generally quite subtle so don’t affect the overall aesthetic of your piece of jewellery. The thinner or smaller your piece, the less noticeable the colour difference will be.

As an industry standard, most white gold is rhodium plated. This means you’re not actually seeing the natural colour of the metal as it is plated in a thin layer of rhodium, which is a naturally white metal, so that the stunning bright silver-colour appears consistent no matter the carat. This finish is generally reapplied annually when rings are serviced to maintain the colour.

If you’re opting for an un-plated white gold, the natural colour of the metal in 9ct is slightly darker than sterling silver. You will find that the 9ct looks silvery, and then the higher the carat the darker the grey tone becomes, resulting in more of a steely grey with a slight warmth, making it a popular choice for mens wedding rings.

9ct rose gold is a soft pink, while 14ct and 18ct are a much warmer, peach-toned colour. Our 18 carat rose gold alloy is always popular for its soft warmth and lack of coppery undertone.

9ct yellow gold appears as a subtle, pale yellow while higher carats, such as 18ct in particular, present a richer, more vibrant golden tone. As a 9 carat alloy is more diluted with other metals, there can be some minor colour evolution or tarnishing over time, whereas 18 carat has a more stable finish.

The carat finish can be identified by a small stamp (hallmark) located on the gold, typically in a discreet spot such as the inside of a band, the clasp of a necklace or bracelet or the post or butterfly of your earrings.

WAYS TO MEASURE

Want to match the size of a ring you already own? Simply use a ruler to measure the inside diameter in millimetres - this means your measurement will not include the ring itself.

You may also use the below standard sizing as a guide only, particularly if purchasing as a gift.

Small | AUS size L

Medium | AUS size N

Large | AUS size P

Please take care when specifying your size, if the wrong size is ordered and the piece requires resizing, a resizing fee applies and this varies from piece to piece.

Local customers are welcome to visit the studio to be sized, or you can order our complimentary ring sizer here to find your perfect size at home.
