Try ARCA's Custom Cut
Custom Cut is a distinctive cut, designed to feel as personal as your story while preserving the clarity, brilliance, and facet-by-facet light of a classic center stone.
We Believe
Classic Design, Made for Every Moment
A true classic feels natural from the first wear. Each ARCA piece is shaped through precise cutting, a gently curved band, and refined micro-pavé setting, creating clean brilliance in sunlight, candlelight, and the everyday moments you share. It is made not only for one special day, but for daily life together.
Crafted for Daily Wear
ARCA starts with structure: bands of 2.2 mm or wider, secure prong settings, reinforced galleries, and rounded closed prongs. This construction helps protect the center stone from everyday knocks, reduces snags and scratches, and keeps the ring smooth and comfortable on the hand. Whether you are working, traveling, or celebrating, your ring is designed to feel secure and easy to wear.
Considered in Every Detail
ARCA refines every angle, curve, and micro-pavé setting to bring out fire, brilliance, and comfort. Each inner band is polished smooth for gentle wear, while exacting standards turn a heartfelt promise into a piece of light you can hold.
ARCA Standard
ARCA Standard
ARCA rings are designed with graceful, flowing lines. Our setting helps secure and protect the center stone while creating a clean, minimalist profile that feels elegant, fluid, and refined from every angle.
Eligible ARCA center stones include IGI Certification. For each eligible ring, our experts review a curated selection of qualifying stones against the TrueSpark™ standard, considering cut quality, symmetry, polish, proportions, depth/table ratio, light performance, and how naturally the final stone fits the ring profile.
Each ring is meticulously polished inside and shaped with a streamlined comfort fit. The smooth, rounded inner edge helps reduce friction against the skin, so the ring feels light, secure, and easy to wear from day one, whether for all-day wear or special moments.
ARCA considers symmetry, proportion, and light performance for each shape. The goal is a center stone with lively brilliance, a balanced profile, and a natural fit in the setting.

With more than a decade of diamond-industry experience, the ARCA team developed TrueSpark™ , a selection standard that looks beyond basic grading. We consider cut quality, symmetry, polish, proportions, depth/table ratio, light performance, and how naturally each stone fits the design, so the finished ring feels bright, balanced, and intentional.
