Diamond specialist Mikisa Gems introduces UltraBrights, a curated selection of melees featuring an innovative cut that optimally enhances a diamond’s brilliance, fire and scintillation.

Mikisa Gems, supplier of finely cut small diamonds, is at the forefront of a diamond cutting evolution. The company, which has roots in India and Belgium, has unveiled a modern and highly efficient way to cut round melee diamonds.

UltraBrights is a new patented cut that magnifies the gem’s brilliance without compromising scintillation and fire, according to Mark Goossens, UltraBrights designer and partner at Mikisa Gems.

"As specialised manufacturers of small sized diamonds, we realised that the rules that apply to larger stones do not necessarily apply to smaller stones,” revealed Goossens. “Understanding this, with our more than 35 years of experience, we’ve developed a cut that unravels the true beauty of small round diamonds.”

An alternative to traditional round brilliant cut melee diamonds, the UltraBrights cut was the result of hundreds of theoretical models and prototypes, computer simulations and interactive consumer feedback, the company official said.

An UltraBrights diamond has 49 facets as opposed to 57 in a normal round brilliant cut stone. The design specifically enhances the visual appearance and improves the light optimisation of very small diamonds. UltraBrights diamonds are best suited for pavé settings or as accent stones.

Market surveys likewise confirmed that UltraBrights diamonds appear brighter than their ordinary counterparts. With optimised brilliance and a distinctive star pattern on the pavilion side, UltraBrights give jewellery designers an opportunity to differentiate their melee diamond product offerings.

The product was launched in South Korea in collaboration with Korean jeweller Golden dew during the Belgian state visit in March. Customer feedback on UltraBrights has been extremely positive, according to Goossens.

Mikisa Gems mainly supplies diamonds, including melees and special cuts, to the Swiss watch industry and high-end jewellery manufacturers. Other markets include France, Germany, Italy, India, Thailand and most recently, South Korea.

The company is eyeing business opportunities in Asia, China and Japan in particular.


Mikisa Gems has built a solid reputation over the years as a trusted manufacturer of top-quality brilliant and single cut diamonds of 0.5mm to 3.6mm. At the heart of the company’s success are innovation and creativity.

“It will become even more difficult to have a successful business in the ‘generic segment’ hence the need to innovate and be creative,” remarked Goossens. “We work on various levels: Manufacturing technology and methodology; product evaluation systems; and special cuts.”

Each level is permeated by a tremendous degree of professionalism and expertise, resulting in highly sought-after, top-grade small diamonds.

Following the success of UltraBrights, the company is working on other projects aimed at developing proprietary cuts, remarked Goossens, adding that this has become a differentiator for many jewellery manufacturers and retailers. As a natural diamond producer, Mikisa Gems also promotes transparency and consumer confidence in the trade.

“Our customers require full transparency in the pipeline. As such, we have established an internal tracking system. We can trace each stone to the rough that it was manufactured from. We check at various levels in our pipeline whether all the stones are 100 percent natural,” noted Goossens.
