Highest Diamond Quality

As the largest online diamond retailer, BA.SG offers the most extensive collection of the world’s finest cut diamonds.

Each loose diamond is accompanied by a grading report from the GIA and IGI, their are an independent diamond grading lab highly respected for their consistency and stringent grading standards.

Diamond Jewellery

For exceptional quality, the diamonds set in our jewellery meet strict minimum quality standards. Each diamond is colourless to near-colourless (D–I grade colour) with exceptional clarity (FL–I2 grade clarity). This standard of quality applies to all our diamond jewellery — even pieces with the smallest diamonds.

Black diamond fashion jewellery is crafted using natural diamonds that have been treated to create a unique black colour with a high lustre. It is common for black diamonds to reveal minor surface imperfections without magnification.
