D Diamond New York, a distinguished name in high-end pet accessories, has broadened its exclusive collection, extending its opulent designs from canine companions to sophisticated felines. Originally established in 2025 by Racheli Waters Shamir, the brand initially captivated the dog luxury market with handcrafted 18k gold collars embellished with diamonds and various colored gemstones. These pieces, ranging from approximately $1,400 to custom creations fetching seven figures, positioned D Diamond as a pioneer in American fine jewelry exclusively for dogs. Now, the brand ventures into uncharted territory, offering a dedicated line for cats, acknowledging their unique allure and the growing demand for luxury pet items.

The expansion into feline fashion with the 'C Collection' not only caters to an underserved segment but also recognizes the historical reverence for cats, reminiscent of ancient Egyptian times when these animals held elevated status. The collection, which launched on July 1, emphasizes elegance and safety, featuring collars made from 18k yellow or white gold, accented with pink tourmalines, emeralds, ametrines, and both natural and lab-grown diamonds on the locks. This move reflects a broader trend of pet owners investing significantly in their animal companions, with the American pet industry witnessing substantial spending, highlighting a lucrative market for bespoke pet adornments.

Elevating Feline Luxury: The Genesis of D Diamond's C Collection

D Diamond's foray into the feline luxury market marks a significant milestone, building upon its established success in high-end dog jewelry. The brand, founded by Racheli Waters Shamir in 2025, initially carved out a niche by offering exquisite, handcrafted 18k gold collars for dogs, adorned with diamonds and an array of vibrant colored gemstones. These early offerings, ranging from entry-level luxury to bespoke, million-dollar creations, swiftly positioned D Diamond New York as a leader in fine pet jewelry. The decision to expand into feline accessories was driven by an observation of an underserved market and a recognition of cats' inherent elegance and mysterious charm, which Shamir believes perfectly aligns with the allure of fine gemstones.

The 'C Collection,' unveiled on July 1, is meticulously designed to celebrate the distinctive qualities of cats. Unlike merely resizing existing dog jewelry, Shamir consciously developed a separate line, ensuring that each piece complements the feline form and temperament. The collection showcases 18k yellow and white gold collars, embellished with precious stones such as pink tourmalines, emeralds, and ametrines, complemented by diamonds on the locks. This expansion is a testament to the brand's innovative spirit and its commitment to offering unparalleled luxury for all cherished pets, tapping into a market where pet owners are increasingly willing to invest in high-quality, durable, and aesthetically pleasing accessories for their animal companions.

The Artistry and Innovation Behind D Diamond's Feline Offerings

The 'C Collection' for cats is not merely about aesthetics; it embodies D Diamond's dedication to craftsmanship, safety, and comfort. Racheli Waters Shamir emphasizes the unique energy and mystery associated with felines, believing that these qualities resonate beautifully with the intrinsic value and symbolic meaning of fine gemstones. Each collar is a piece of art, meticulously crafted from 18k gold and set with a choice of natural or lab-grown diamonds, alongside an assortment of colored gemstones. This thoughtful selection ensures that every item in the collection is not only visually stunning but also carries a sense of individuality and significance for both the pet and its owner.

A critical aspect of the 'C Collection' is its innovative safety features. Shamir highlights a specially designed, tamper-proof locking mechanism that is both secure and hypoallergenic, ensuring the pet's well-being. Rigorous testing on animals, including those with pre-existing head and neck sensitivities, confirmed the comfort and non-irritating nature of the jewelry. This commitment to both luxury and practicality distinguishes D Diamond in the rapidly expanding pet industry, where American consumers spent a staggering $158 billion on their pets in 2025. The brand's expansion also includes future plans for equine-themed accessories, starting with charms, indicating a continuous pursuit of new horizons within the luxury pet market and an understanding of the profound emotional connection between owners and their beloved animals.
