Please note, this piece is made to order based off your desired specifications above. If you’re wanting your piece immediately, please consider choosing from our Ready To Wear range.
Moissanite
A moissanite is its own unique gemstone, just as sapphires and emeralds are their own unique gemstones. Moissanite, however, boasts a similar durability to a diamond, as well as an uncanny visual resemblance to a diamond, making it the perfect alternative for bridal jewellery.
Moissanite is a more affordable option when compared to cultured diamonds, ranging between $1,200.00 and $5,000.00+. Moissanite allows you to indulge in your dream ring design and a larger carat size, without exceeding a reasonable budget.
A moissanite is the perfect choice for somebody who desires the highest quality diamond alternative, that is ethical and attainable.
Lab Grown Diamond
A laboratory grown diamond is chemically and optically the same as a mined diamond. They are one in the same - real diamonds. A lab grown diamond, however, is created above ground sustainably, with advanced technology mimicking the natural growth process of a mined diamond.
Cultured diamonds are more expensive than moissanite, ranging between $2,100.00 and $15,000.00+. However, they are significantly more affordable compared to their mined counterparts.
A laboratory grown diamond is the perfect choice for somebody who desires a real diamond with ethical origins.
Crafting Timeframe
We lovingly craft our pieces in Australia, in our Brisbane workshops. Our Bespoke Process (Ring Builder) and Complete Custom Designs are made to order with a current turnaround of 7-10 weeks. Our Ready To Propose Collection are ready for purchase and resizing with a turnaround of only 2 weeks.
Standard Crafting
Our bespoke crafting turnaround aims to ensure your piece will be completed within 7-10 weeks, excluding our two week holiday closure period.

Carat
Carat refers to the weight of a diamond. Moissanite and diamonds don’t weight the same, so we place emphasis on the phrase carat equivalent. Our carats of moissanite are determined based on the visual appearance of the diamond carat equivalent on the hand. This means, if you’re choosing a 2 carat moissanite it will visually appear the same on the hand as a 2 carat lab diamond, irrespective of the actual weight.
Colour
Colour refers to a gemstone's natural colour, not the coloured flashes of light the diamond emits when it moves, known as fire. Colour is graded alphabetically from D (Colourless) to Z (Light Yellow).
Lab Grown Diamonds
We primarily work with IGI and GIA certified lab grown diamonds that range between the DEF colour range, to ensure the whitest and brightest appearance.
Moissanite - Colourless
Our signature Eternal Brilliance Moissanite is D - Colourless. This is the most diamond-like, and the most beloved moissanite gemstone colour choice amongst our couples.
Moissanite - Champagne
We offer a bespoke range of champagne coloured moissanite, ranging from a light yellow tone to a deep cognac.
Moissanite - Coloured
We offer an extensive range of coloured moissanite. Design your dream ring with a burst of colour.
Clarity
Clarity refers to the inclusions found in a gemstone. These can occur during the growth methods utilised when created in a laboratory. Our Eternal Brilliance Moissanite boasts a clarity of VVS1.
Faceting
Faceting refers to how the gemstone has been cut and determines the internal appearance of the stone itself, rather than the shape. Moissanite gemstones can be cut and faceted to change the stone’s overall visual appearance, including its fire and brilliance.
Bespoke Customisations
A bespoke customisation is the perfect way to add individual flair to your dream ring. Choose from a pavé band, hidden halo or pavé bridge. These customisations are available in both moissanite or lab grown diamonds.
Hidden Birthstones
Select up to four Hidden Birthstones in order of desired placement. We proudly utilise lab-grown hidden birthstones that align with our stance on ethicality. For more birthstone information, simply click on your desired birthstone to learn more.
Please Note:
This incurs an additional fee of $100.00 per birthstone.

Ring Size
All rings crafted by TMC are bespoke and can be designed to your exact specifications, including ring size. We utilise Australian Standard Sizing.

Faceting
Faceting refers to how the gemstone has been cut and determines the internal appearance of the stone itself. Unlike diamonds, which are cut to maximise carat weight, moissanite gemstones are cut and faceted to maximise the divine fire and brilliance we all adore. Depending on the chosen cut, two stones in the same shape can appear quite differently, as the contrast between white light and the dispersed coloured light within the gemstone also differs.
Brilliant Cut Faceting
The brilliant cut is optimised to refract the most light, and therefore sparkle the most. Light will go down into the centre of the stone, reflect off of the clear and precise facets, and come back out through the stone.
Available For: Round, Oval, Pear, Radiant, Marquise, Elongated Cushion, Cushion.
Crushed Ice Faceting
A crushed ice moissanite stone has a multitude of small, randomised facets within the pavilion of the stone. Typically, the light will reflect multiple times inside the stone, sometimes exiting instead of reflecting back up.
Available For: Oval, Radiant, Pear, Marquise, Elongated Cushion, Cushion.
Old Mine Faceting
Old mine cut moissanites have a beautiful, unique appearance that dates back to an era when diamonds were cut and polished by hand. Their deep, large facets produce a unique fire, giving the cultured gemstone a softer look than modern brilliant gemstone cuts.
Available For: Oval, Elongated Cushion, Cushion.
Old European Faceting
The old european cut is a round gemstone cut. Primarily cut between 1890-1930, this faceting type has a softer look than modern brilliant gemstone cuts and is easily recognizable by the small circle at the centre of the diamond's table.
Available For: Round.
Rose Cut Faceting
Rose cut gemstones boast a domed table covered in distinctive triangular facets. The fewer facets of a rose cut diamond result in the subtle beauty of a soft diffused light - a divine choice for those dreaming of something truly unique.
Available For: Oval, Pear.
Step Cut Faceting
Step cut faceting is distinctive to the Emerald and Asscher cut gemstones wherein the gemstone is produced with flat steps or 'rows' of four-sided facets parallel to the girdle. Striking and regal, the emerald cut is reminiscent of the 1920's era.
Available For: Emerald, Asscher.
