Ursula Rickmers Jewelry

This 2.19-carat Tanzanian sapphire shifts color depending on the light, moving between soft mint green and a cooler teal. It's the kind of stone that looks slightly different each time you glance at it, which makes it hard to stop looking. The kite cut gives the sapphire an angular, elongated silhouette that extends gracefully along the finger. It's a less common shape for sapphires, which tends to appeal to people who want something outside the usual options. You can see into the stone clearly here, following its internal structure and the way light moves through it. At Ursula Rickmers Jewelry, we set this sapphire in 18k yellow gold. The warmth of the gold draws out the stone's golden-green tones while letting the cooler teal notes provide contrast. Six prongs hold the kite shape securely without crowding its edges. The ring is handcrafted in our Istanbul atelier, steps from the Grand Bazaar where jewelers have been refining their craft for centuries. Tanzanian sapphires like this one, with their natural color-shifting properties, offer something different from the classic blue. Whether as an alternative engagement ring or a piece you're choosing for yourself, this kite sapphire...

This 1.07-carat round salt-and-pepper diamond has a champagne warmth to it, with gray and golden tones mixing throughout the stone. The inclusions give it a galaxy-like quality, scattered across the body like dust. Light moves through it easily, catching the facets and revealing different colors depending on the angle. An octagonal halo of white diamonds (0.15 carats total) surrounds the center stone, their bright sparkle framing the warmer tones of the salt-and-pepper diamond. The geometric shape of the halo gives the ring an Art Deco quality, adding structure to the organic character of the center stone. At Ursula Rickmers Jewelry, we set this ring in 18k rose gold. Four prongs secure the center diamond within the octagonal frame, and the band has a knife-edge profile that tapers delicately toward the setting. The warmth of the rose gold amplifies the champagne tones in the diamond, creating a cohesive, romantic palette. The ring is handcrafted in our Istanbul atelier, steps from the Grand Bazaar, where jewelers have been refining their craft for centuries. The inclusions in this diamond formed over millions of years in a configuration that exists in no other stone. Whether worn as an alternative engagement ring or chosen for your own reasons, this octagonal halo ring...

This 1.23-carat kite-cut salt-and-pepper diamond has an icy, wintry quality to it. Light gray with a soft scatter of inclusions throughout, the stone feels like looking through frosted glass. The kite shape elongates along the finger, its four points giving the diamond an almost compass-like geometry. The band has its own character. Rather than a traditional round profile, the 18k white gold is faceted with clean, angular edges that echo the shape of the stone above it. It's a subtle detail, but one that ties the whole design together. At Ursula Rickmers Jewelry, we paired the cool tones of this salt-and-pepper diamond with white gold deliberately. There's a cohesion to it, the metal and stone working in the same temperature range rather than creating contrast. Four prongs secure the kite at each point without interrupting its lines. The ring is handcrafted in our Istanbul atelier, steps from the Grand Bazaar, where jewelers have been refining their craft for centuries. Whether this kite diamond...

At the center of this ring by Ursula Rickmers Jewelry sits a 1.15 carat hexagon grey diamond with a rose-cut surface, its broad, flat facets giving you an unobstructed view into the stone's interior. The grey diamond is heavily saturated, leaning toward charcoal with clouded passages and darker mineral traces visible beneath the facets. Rose-cut hexagons have a particular way of handling light: instead of the sharp sparkle of a brilliant cut, they produce a softer, more reflective glow that changes as the stone tilts, almost like light moving across still water. The band builds outward from the grey diamond in layers. Immediately flanking the hexagon, two baguette-cut diamonds totaling 0.10 carats create a geometric bridge between the center stone and the pavé shoulders. From there, small round brilliant diamonds totaling 0.06 carats continue along the 18k white gold band, adding a line of fine brightness that extends halfway around the ring. The progression from hexagon to baguette to round gives the design an architectural rhythm, each cut type serving a different purpose in the overall composition. Handcrafted in our Istanbul atelier by artisans whose techniques trace back to the Grand Bazaar, this grey diamond ring...

This 1.87-carat kite-cut salt-and-pepper diamond leans toward the darker end of the spectrum, with deep gray and black tones concentrated in its center and lighter, almost translucent edges. The gradient gives the stone a sense of dimension, like looking into smoke. The kite shape extends vertically along the finger, its four points secured by teardrop-shaped prongs at the top and bottom. Pavé diamonds (0.15 carats total) run along the band, their brightness drawing a clear line between the moodiness of the center stone and the sparkle surrounding it. At Ursula Rickmers Jewelry, we set this ring in 18k white gold, which keeps the overall palette cool and cohesive. The band has a considered weight to it, substantial enough to balance the angular center stone without competing for attention. The ring is handcrafted in our Istanbul atelier, steps from the Grand Bazaar, where jewelers have been refining their craft for centuries. Once this ring finds its owner, there won't be another to take its place. Whether worn as an alternative engagement ring or chosen on your own terms, this kite diamond ring...
