Setting FAQ's


We proudly handcraft all of our settings by hand in China. As a Hong Kong-based brand, we keep craftsmanship close to home and exclusively work with select artisans that have decades of experience in crafting.

Yes, to keep mining to a minimum, we recycle 14k gold, 18k gold, palladium, and platinum. This ensures the smallest amount of impact and stunning jewelry at it's finest.

We offer great warranty coverage on all lab-grown diamonds; however, we currently do not have a warranty on the mounting itself. Jewellers that provide this kind of warranty often require you to bring your rings in for maintenance every 6 months. As we are a web-based shop, this would require you to ship your jewelry to use twice a year, which would incur high fees on your part. We offer all our repairs at cost and have found our customers save far more by just sending their jewelry to us when maintenance is needed.

Should there be any manufacturing defects on our settings, we will cover all the costs associated with the repair or remake, plus we will reimburse you for any shipping fees paid. We're to offer free cleaning services as well as free center/side stone tightening at any time, the only cost you'll have to cover is shipping. Other repairs, such as accenting stone replacement, resizing, polishing, prong repair, etc. have expenses associated with them.

All of our accenting diamonds under 0.20ct are recycled from mined diamond chips or older repurposed settings. Our recycled earth-mined diamonds are from a source that honors the Kimberley Process. The Diamond Library will only use mined diamonds when absolutely necessary. All of the recycled diamonds used in Diamond Library settings are guaranteed to be a minimum of G-I in colour and SI1 in clarity.
