Rated 4.8/5 from 8 Google reviews.

This isn't a flashy boutique with champagne service and inflated markup. It's a working jewelry shop where knowledge and fair dealing matter more than presentation. The staff will spend an hour explaining diamond grading without pressure to purchase. Bring your own design ideas or browse their completed custom pieces for inspiration.

Supaporn Diamond is a retail store in Chakkrawat, Samphanthawong. This family-run jewelry shop specializes in diamonds and precious gemstones sourced from reputable suppliers. The store offers custom design services for engagement rings and wedding bands. Customers can choose from certified diamonds in various cuts and clarity grades. Gold jewelry in both Thai and contemporary styles fills the temperature-controlled display cases. The staff provides GIA or local authentication certificates for all diamond purchases above one carat. Walk-ins can browse the selection or schedule private appointments for custom consultations and fittings. Prices reflect wholesale market rates common in Bangkok's historic jewelry quarter near Yaowarat Road. The shop maintains long-term relationships with gem cutters and goldsmiths throughout Thailand and Myanmar. Many customers return for jewelry repairs and stone replacements over the years. The store accepts both cash and major credit card payments with invoice documentation. Security measures include 24-hour surveillance cameras and reinforced display cabinets with electronic locks. Operating hours typically run from late morning through early evening six days weekly.

The showroom occupies a narrow shophouse typical of Chinatown's commercial architecture from the mid-20th century. Natural light supplements the focused LED spotlighting that illuminates each piece without excessive glare. Most visitors are Thai couples shopping for wedding jewelry or Chinese-Thai families purchasing investment gold. The atmosphere remains professional yet relaxed compared to high-end mall boutiques in Siam or EmQuartier. Staff members speak Thai, Mandarin, and functional English for international customers. Parking is challenging in this dense neighborhood but motorcycle taxi stands operate nearby. The nearest MRT station is Wat Mangkon about 800 meters away on foot. Serious buyers should allow 30 to 45 minutes for initial consultations. Custom orders typically require two to three weeks for completion depending on design complexity.
