The Heritage of Nature

A Legacy Crafted by Earth.

Formed deep within the Earth over billions of years, every natural diamond carries a story shaped by nature.

At S.Diamond in Bangkok, we thoughtfully select natural diamonds for engagement rings, wedding bands, and fine jewelry—creating meaningful pieces that reflect your personal story.

“Nature creates the extraordinary. We make it yours.”

NATURAL DIAMOND EXPERTISE

Natural Diamond Expertise, Thoughtfully Curated.

GIA Reports & Transparency

For qualifying natural diamonds, GIA grading reports provide independent information on the stone’s characteristics, helping you compare options with clarity and confidence.

At S.Diamond, GIA reports accompany round brilliant diamonds from 0.18 ct and fancy-shaped diamonds from 0.30 ct. Smaller stones may have an S.Diamond Certificate.

Expert Diamond Selection

From Round Brilliant to Fancy Shapes, we evaluate natural diamonds for their proportions, finish, visual brilliance, and overall appearance— not simply the grades shown on a report.

For round brilliant diamonds, we generally prioritize GIA Triple Excellent and evaluate Hearts & Arrows patterns where applicable.

Lifetime Jewelry Care

Our after-sales care includes professional cleaning, prong inspections, and practical guidance for looking after your fine jewelry.

Services are subject to applicable warranty and after-sales care conditions.
