Diamond Rings and jewellery Engagement Rings and Fine Jewellery from Polished Diamonds NZ

Welcome to Polished Diamonds and our remarkable jewellery business based here in New Zealand.  We design and create diamond engagement rings, wedding rings and fine jewellery items. Buying an engagement ring is about trust in the jeweller and we guarantee the highest quality, best price and an exciting and memorable shopping experience.  To ensure you are receiving both a high quality item at excellent value we have the following assurances: 

We custom design each engagement ring or fine jewellery item using architectural computer aided design (CAD).  This enables the most accurate and precise diamond jewellery possible - it doesn't get any more dimensionally perfect than what we create.  Clients preview their unique ring design in accurate CAD proportion so they can decide on style adjustments to ensure it looks perfect. We can email these design images so simply contact us - or pop into our relaxing design studio in New Regent Street.  Upon design confirmation we 3D print a wax/polymer model which creates the dimensionally perfect, error free engagement ring model which is negatively cast into Platinum or Gold. Each ring is then hand polished, hand set with your chosen diamond or gemstone and hand finished to perfection.  This process produces the most accurate engagement rings possible and we back our beautiful rings with a lifetime guarantee - you can't get better than that.

As a factory-direct jewellery workshop we offer the best pricing at this quality level - period. There are no middlemen as we produce what we sell ensuring the best price, best quality, direct to you.  We even beat the mass produced chain stores on price and yet our quality is so much higher. We sell GIA certified diamonds for your trust and assurance that the grading is accurate and these are also laser engraved for security.  These diamonds have an excellent cut for a high performance sparkle.   Explore our loose diamond database of over $120m of GIA diamonds.  We are JWNZ members and won 'Best Retail' at the business awards.
