Coloured gemstones are among the most dynamic elements in the global jewellery industry, catering to growing demand for pieces that embody individuality and emotional resonance, according to mine-to-market coloured gem enterprise Miranda Group.

Cam Li, managing director of Miranda Group, said discerning buyers increasingly prefer gems with unconventional colours, vibrant hues and special cuts over diamonds. This desire for personalisation also extends to jewellery.

“Top-tier gems remain highly prized by collectors, with rising preference for extremely rare and high-value gemstones. Today’s consumers are also gravitating towards one-of-a-kind jewellery,” said Li.

Amid robust demand for coloured gemstones, the supply side presents multiple challenges. New gemstone discoveries are limited and mining yields for high-quality deposits remain scarce. Adding to production pressures are stringent environmental regulations that restrict mining; impacts of climate change; and geopolitical tensions that complicate logistics and export policies.

Despite these headwinds, Miranda Group’s expertise in gem sourcing and production enables it to chart a steady course. The company’s vertically integrated operations – spanning associate mines in Brazil and Africa, its Chinese manufacturing facility, and cutting operations in Brazil – have bolstered its resilience amid market uncertainties.

New launches

In 2025, Miranda Group unveiled a new collection, Rubelite Ouro Fino, featuring rubellites produced from one of its associate mines in Nigeria. According to Li, the gems in this collection bear exceptional qualities and colours comparable to those found in the renowned Ouro Fino Mine in Minas Gerais, Brazil, which was discovered three decades ago.

“Rubellites featured in the Rubelite Ouro Fino collection are meticulously cut and polished to the highest quality. This collection celebrates rubellites for their ruby-like tones of lustrous pink-red to red colour, and nearly flawless clarity,” Li noted. “These gems’ impeccable purity and colour make them exceptionally valuable.”

Another highlight of the year was the Glow Set Paraiba and Emerald, featuring brilliant-cut gem layouts of various shapes such as oval, pear and square-Asscher cuts. Each layout underscores Miranda Group’s expertise in innovative designs and precision cutting.

“Paraiba tourmaline is highly sought after, particularly in small round shapes ranging from 2mm to 6.5mm. Both matched pairs and single stones of medium to high quality enjoy solid demand,” Li added. “We expect these gems to gain further traction in the market.”

Sustainability

Miranda Group’s journey towards growth is anchored in a steadfast commitment to responsible and ethical mining and sourcing practices. Transparency and sustainability serve as cornerstone principles throughout its value chain, backed by Environmental, Social and Governance (ESG) initiatives.

“We fully implement mining policies in line with regulations and take an active lead in climate initiatives by setting decarbonisation targets,” Li explained.

This involves optimising energy efficiency in production processes, improving supply chain transparency by working with partners to track emissions, reducing transportation distances, and implementing water and resource recycling practices at its mining facilities. The company’s goal is to minimise its ecological footprint and achieve zero waste.

Vibrant future

Li expects demand for exotic and high-quality coloured gemstones to continue its upward trajectory in 2026 as consumers increasingly explore alternatives to diamonds.

Despite economic uncertainties and the unpredictable nature of US tariff policies, the company's ongoing enhancements in management systems alongside its diverse manufacturing presence across regions will play a pivotal role in fostering growth and adaptability during challenging times.

“With a combination of technical mastery, innovative design and ethical standards, Miranda Group is strategically well-positioned for a thriving future within the coloured gemstone market,” Li remarked.
