An old mine cushion in fancy yellow, held within a Georgian-inspired gold setting that deepens the warmth of the stone rather than competing with it.
The broader facets and softened outline give the diamond a slower, more irregular play of light than a modern cushion. In yellow, that old-mine character becomes especially rich: flashes of brightness move through a deeper field of colour, while the close gold frame gives the piece weight and definition.
It has presence without feeling overly polished. The character comes from the stone, the weight of the gold and the simplicity of the setting.

Fancy yellow old mine cushion centre diamond in a Georgian-inspired gold setting
Made to order and handcrafted in Australia
Available in platinum, 18K white gold and 18K rose gold by request
Each centre diamond is selected individually for colour, facet pattern, proportion and how it presents on the hand. Unlike colourless diamonds, fancy yellow diamonds are valued first for the strength, evenness and character of their colour. Starting prices are based on Fancy Yellow colour and VS1-VS2 clarity, with each centre diamond accompanied by its independent IGI or GIA grading report.
Old mine cuts are selected for their softened cushion outline, broader facets and more individual proportions. Two stones of the same carat weight can look quite different, and with fancy yellow diamonds the facet pattern also affects how the colour is held and returned. We select for face-up presence, balance and a rich, even yellow rather than the carat number alone. For laboratory-grown stones, “old mine” describes the antique-inspired cut character rather than the age of the diamond.
Every MARLII LAB engagement ring is made to order and crafted by hand in Australia. Please allow 10-12 weeks once your design and centre diamond are confirmed.
The setting is made around the proportions of your chosen diamond rather than pulled from stock or adapted from a finished ring. The timeframe gives the workshop room to make and finish the piece properly, without rushing the details that matter.
If you are working to an earlier proposal, travel or celebration date, an express making service may be available for an additional $1,100, subject to workshop capacity. Please let us know your required date before ordering so we can confirm what is possible.
