Founded in 2019, BA.SG has quickly grown to become one of the largest online retailers of certified diamonds and fine jewellery in South-East Asia.

The company is built on a unique idea: choosing an engagement ring doesn’t have to be complicated. Diamonds can be simple to understand. Making the right choice can be easy. This unique approach and reputation for excellence has gained notice from publications around the world.

BA.SG has been recognized as the best in online customer service as ranked by actual consumers. BA.SG is one of the few jewellers to have ever received this award, and has done so every year since 2019. Together with experienced craftsmen and designers, who held the passion to create new generation jewellery, BA.SG launched a series of “majestic designs” for wholesale. The design was made up of 4 marquise diamonds, set with 1 princess cut diamond in the centre with invisible claws. The orders were piling up, and the operation of service centre was pressured into expanding at a fast pace. BA.SG was probably the only production team in Singapore which sets a large quantity of “majestic designs” locally.

Today, BA.SG service centres in Singapore and Hong Kong houses accredited gemologists and designers ensuring the quality and aesthetics of our jewellery. It uses cutting-edge machinery for designing jewellery with detailed 3D configuration, making customised wedding bands with computer-engraved wedding bands. When the delicate fine art of jewellery cannot be substituted by technology, BA.SG craftsmen showcase their skill to hand-craft jewellery.

At BA.SG, you’ll find high-quality diamonds certified by the most respected independent diamond grading labs. You can create your own jewellery — choose the right diamond and we’ll set it in your favourite earring, pendant, or ring design. Every order is shipped free, guaranteed and returnable within 30 days, so you can be sure you made the right decision.
