Diamonds, though often synonymous with refinement, are in fact one of the most rugged materials on the planet—a quality best displayed in expensive jewelry fashioned from uncut stones. The following five designers’ exclusive jewelry pieces made by rough-cut diamonds that Luxury Safes shows to you, serve as beautiful reminders that the hardy gemstone is truly one of Earth’s great wonders.

Sally Agarwal

London-based designer Sally Agarwal uses softly tumbled, unfaceted polki diamonds in her debut collection. Such stones were used in India, where Agarwal studied jewelry design for many years, for traditional ceremonies in the royal courts. The gems glow in Agarwal’s three-strand bracelet ($20,000).

Gurhan

Delicate and pliable, the 24-karat gold used in New York–based designer Gurhan Orhan’s luxury jewelry is easily shaped, but also easily damaged, during the exclusive design process. Gurhan studied thousand-year-old goldsmith techniques to prepare for this challenge posed by the soft metal. Rough-cut diamonds and diamond slices are a perfect complement to Gurhan’s naturalistic, soft-edged designs, like this luxurious and delicate necklace.

Coomi

Drawn to themes of antiquity, Coomi Bhasin’s upbringing in India is reflected through the intricate metalwork she uses to frame her selection of rough-cut diamonds alongside other shining materials. This bespoke approach is visible in Coomi’s Luminosity 20-karat-gold, art deco–style cuff ($55,000).

Sanjay Kasliwal

New York–based designer Sanjay Kasliwal handcrafts luxury jewelry that is at once ornate and totally wearable, demonstrated in this silver and 14-karat-gold Eternity band, featuring round and rose-cut diamonds ($4,000).

Todd Reed

Todd Reed has melded unusual and outright beautiful materials since he launched his expensive jewelry brand in Colorado about 30 years ago. These raw-diamond designs are no exception, spotlighting an 18-karat yellow-gold wrist cuff centers on a mosaic of rose-cut diamonds and raw-diamond cubes ($8,800).
