Milgrain beading traces the edge of every ring, one of the most exacting details in vintage jewelry craftsmanship, lending the whole piece a warm, enduring classic quality. The same attention to detail continues at the bail, accented with diamonds and sapphires, so the sparkle flows unbroken from the collarbone down to the pendant itself — nothing left to spare. The warm tone of 18K yellow gold makes the sapphire's depth all the more striking, like the brightest star in the night sky, gently set within ring after ring of soft radiance. Celestia Crown is for anyone who appreciates the details, who's drawn to vintage elegance — it needs no excess ornamentation; the layered halos alone tell a story that belongs to the classics, one that only grows richer with time. 【Design Highlights】 Double-Halo Setting: Densely set diamonds in the inner ring, alternating diamonds and sapphires in the outer ring, for rich, layered brilliance Milgrain Vintage Setting: Fine beading traces every ring's edge, one of the most exacting details in vintage jewelry craftsmanship Oval Sapphire Center Stone: Its deep color sits at the heart of the piece, the visual focal point Detailed Bail: Continues the same sparkle from the collarbone to the pendant Two Size Options: Choose between a 0.3-0.4ct or 0.7ct center stone to suit your preference Sapphire has long been regarded as a symbol of wisdom and loyalty, its deep blue associated across both Eastern and Western cultures with serenity, truth, and noble character. Ancient Persians believed the sky itself was blue because the earth rested upon a giant sapphire. Medieval European churches and royal courts also prized sapphire, often setting it into episcopal rings and royal jewels as a symbol of sanctity and nobility. Today, sapphire remains a popular choice for engagement and commemorative jewelry, symbolizing an unwavering promise and a love that only deepens with time. 【About Heat Treatment】 Unless otherwise noted, the rubies and sapphires in our shop are heat-treated. Over 99% of accent-sized rubies and sapphires on the market today are heat-treated, in part because smaller stones are less likely to develop even color saturation on their own and require heat treatment to enhance color depth and uniformity. Heat treatment is a widely accepted industry practice involving only a heating process (no chemical additives), and is recognized by professionals worldwide. The process involves carefully controlled heating between 800–1800°C, which repairs internal fractures and improves clarity. Benefits include: Stable, Permanent Color: Once treated, the color is a permanent change that does not fade over time. Enhanced Beauty: Heat treatment enhances color vibrancy. Accessible Pricing: Heat-treated stones make high-quality gems more attainable compared to untreated stones. Every piece in our collection is hand-selected for excellent cut and the finest color, ensuring a beautiful and satisfying wearing experience. Choosing a heat-treated stone is a smart choice that balances beauty and practicality. 【Production Process】 Once your order is placed, we begin sourcing and setting the stone through our overseas workshop before shipping to Taiwan. As this is a made-to-order piece, production and shipping take approximately 25 business days. Please inquire in advance about center stone availability.
