Rio Diamonds

What Rio Diamonds does

Rio Diamonds Pte Ltd is a Singapore-based direct-to-consumer online jewellery retailer operating under the trade names Rio Diamonds, Rio Diamond, and RIO. The company sells GIA-certified loose diamonds in ten shapes, build-your-own and pre-designed engagement rings across five styles, men's and women's wedding bands, and an 850-plus design fine jewellery catalogue spanning rings, pendants, earrings, necklaces, bangles, and bracelets in 9K-18K gold and platinum, alongside a separate IGI-certified lab-grown diamonds line and a coloured-gemstone collection. Underlying technology consists of conventional in-house diamond quality verification tools (Ideal scope, ASET scope, HCA calculator) and partnerships with master diamond cutters rather than any proprietary software platform. Service guarantees include a lifetime manufacturing warranty, a 30-day exchange policy, complimentary cleaning and inspection, free first-30-day ring resizing, a Lifetime Diamond Upgrade program offering 60-70% credit toward future diamond purchases, and fully insured shipping.

The business operates an asset-light, digital-first go-to-market: the primary sales channel is the e-commerce storefront at the-rio.com, supplemented by an appointment-based physical showroom at Far East Shopping Centre #11-13 in Singapore and international shipping at SGD 150 plus 3% of order value. Pricing is unit-based and spans entry-level pieces from SGD 390 to premium pieces above SGD 6,000, with revenue generated entirely from one-time transactional sales rather than subscriptions or recurring contracts. The customer base is composed of individual consumers, primarily engaged couples purchasing engagement rings and wedding bands and fine jewellery buyers seeking GIA-certified natural or lab-grown diamonds, supported by a VIP registration program and content marketing through diamond education resources. The company is privately held with no disclosed funding, headcount of 1-10 employees, and geographic restrictions limiting service to Singapore residents per its published Terms.
