{"product_id":"round-shank-solitaire-blue-lab-diamond","title":"Ceruleana","description":"\u003cp class=\"ring-narrative\"\u003eA 0.94-carat fancy vivid blue marquise-cut lab diamond on a round shank, in 10k white gold. Fancy vivid is the rarest saturation grade in blue — above fancy intense — and most lab growers can't reliably produce it. The white gold lets the stone do its full work. Ceruleana is the Latin root of the word for the color of deep water.\u003c\/p\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eThe Object\u003c\/strong\u003e\u003c\/summary\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eName:\u003c\/strong\u003e Ceruleana\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilhouette:\u003c\/strong\u003e Round shank solitaire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEdition:\u003c\/strong\u003e One of one\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e US 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollection:\u003c\/strong\u003e Pinky Ring Drop, Spring 2026\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003e\u003cstrong\u003eThe Stone\u003c\/strong\u003e\u003c\/summary\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Lab-grown diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut:\u003c\/strong\u003e Marquise\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCarat weight:\u003c\/strong\u003e 0.94 ct\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Fancy vivid blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClarity:\u003c\/strong\u003e Eye-clean\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 9.81 × 4.88 × 2.11 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccent stones:\u003c\/strong\u003e None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor significance:\u003c\/strong\u003e Fancy vivid is the highest saturation grade in colored diamonds — above fancy intense — and is especially rare in blue, requiring precise boron saturation during growth.

For longevity, we recommend removing the ring during high-impact activity (weight training, rock climbing, manual labor) and avoiding direct contact with harsh chemicals including chlorine, bleach, and acidic cleaners. A soft-bristled brush and mild soap in warm water is sufficient for home cleaning. We offer complimentary lifetime polishing and inspection on every piece.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Catherine Peck","offers":[{"title":"6","offer_id":52800450134295,"sku":"PR-1364312","price":1525.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0993\/8583\/5799\/files\/84.png?v=1779673173","url":"https:\/\/catherinepeck.com\/products\/round-shank-solitaire-blue-lab-diamond","provider":"Catherine Peck","version":"1.0","type":"link"}
