All About A.JAFFE

Founded by the brand’s namesake, Abraham Jaffe in 1892 in New York City, A.JAFFE is widely respected for precisely crafted rings, forged of the finest materials and fitted with 100% conflict-free diamonds. A very small percentage of diamonds are fine enough quality to be used in their world-class rings. Each individual piece takes around 80 hours to craft. Expertise has been passed down from generation to generation for over 120 years, resulting in collections that are true feats of artistic genius.

Engagement ring settings for round-cut rings from A.JAFFE’s Classics, Seasons of Love, and Metropolitan collections

Engagement Rings


Rings in the Classics collection are timeless, refined, luxurious, and elegant. Minimalist silhouettes allow pristinely cut diamonds to take center stage, supported in their beauty by beautifully polished precious metal settings.

Seasons of Love

Seasons of Love engagement rings are more elaborate and evocative, featuring softly curving lines, intertwining bands, and sparkling side stones. Solitaire settings are given an extra bit of visual interest with hidden halos.


The Metropolitan collection is characterized by modern rings with innovative designs. Twisting shanks, double halos, and thick bands heavily-laden with glittering accent stones make these rings truly stand out from the crowd.

Women’s Wedding Bands


Women’s wedding bands from A.JAFFE’s Classics collection are dainty and delicate, inlaid with various sizes and cuts of exquisite diamonds to add even more glimmer to your bridal stack. Hand-crafted prongs hold the gems securely in place and allow them to shine from every angle.

Seasons of Love

Soft curves and intertwining bands characterize women’s bands from the Seasons of Love collection. Seek out this collection if you’re looking for wedding bands with a subtle curve that allows space for the engagement ring’s center stone.


Metropolitan bands are a bit thicker, allowing for larger diamonds and even more shine. Some feature bezel set stones that offer a fresh, sleek feel that is uniquely modern. Browse rings that feature diamonds all the way around the ring, half way, or a third of the way.

Men’s rings in the Plain collection are really anything but basic. Mixed finishes and metals offer distinctive contrast that is at once expressive and timeless. Sort through a variety of finishes, details, and metal work to find a ring that suits your particular style and personality.


As the name suggests, the Diamond collection is distinguished by immaculate gems carefully inlaid into wide bands. These rings are contemporary and extravagant, with unexpected designs and subtle details.

Two Tone

Two Tone rings are distinguished by mixed metal details that make these rings dynamic and visually interesting. For the man looking for something unique, this collection is a phenomenal option.
