Where do Rosendorff source their diamonds?
Rosendorff source diamonds from all over the world including Hong Kong, New York, Tel Aviv and Moscow.  With new owners, Rosendorff customers benefit from international supply relationships and buying power. We also guarantee all diamonds to be issue and conflict free as well as ethically sourced. 

Will my diamonds have a certificate?
Not every diamond will have a certificate.  A large selection of Rosendorff diamonds weighing 0.40ct and above are laser inscribed with a unique identification number and come with a certificate. Certification is an expert opinion of a diamond based on international standards. To be truly appreciated, a Rosendorff diamond needs to be viewed as mere words cannot describe its beauty.

Will I receive a valuation certificate?
Our in-house gemologists are qualified and registered jewellery valuers. Valuations ensure accurate and current insurance coverage. Rosendorff Diamonds provide complimentary valuations on purchases with a retail value of $5000 or greater and by request. Rosendorff will provide valuations for items purchased which are below our $5000 threshold for a small administrative processing fee.

Which is better Platinum or White Gold?
This is a personal preference. 18 carat White gold is an alloy containing 75% pure gold and 25% other alloys. It is hard wearing and is coated in a fine layer of Rhodium which gives white gold its brilliance and whiteness; however it does need regular maintenance with the rhodium requiring replacing every 12 to 18 months depending on how you wear your rings. Platinum is a 95% pure metal in jewellery. It is dense, hard wearing and does not require rhodium plating. It is however, a more expensive metal. We would be delighted to discuss your personal needs when making your purchase.

Which is more important – colour or clarity?
The significance of colour over clarity is one of personal preference. All Rosendorff rings contain diamonds cut to Rosendorff specifications so you can be assured that which ever diamond you choose, it will always be bright and beautiful.

How do I care for my pearl jewellery?
Caring for pearl jewellery is particularly important given the delicate nature of the gem. Contact with chemicals, cosmetics and chlorinated water should be avoided, however your pearl jewellery can still be worn and enjoyed everyday. Due to the porous nature of pearls, avoid submerging your pearls in water as this can dissolve the cement holding your pearl securely in place on its post. When not in wear, store on their own in a soft pouch out of direct sunlight.

What is the difference between Freshwater, Saltwater and South Sea Pearls?
A Freshwater pearl is cultured in a mussel in a lake. A traditional saltwater (Akoya) pearl is cultured in an oyster in the sea. Generally, the freshwater cultured pearls are less expensive than the Akoya pearl. South Sea Pearls are also grown in the sea but are usually a larger size than the Akoya and this is reflected in a higher price point.

I just received my engagement ring but it doesn’t fit. Can I have it resized?

What is rhodium plating?
18 carat white gold is made up of 75% gold and 25% other metal, usually silver or palladium. It is common practice to coat the gold in a fine layer of rhodium which is a metal very similar to Platinum. It enhances the whiteness of white gold. It is hard wearing but will eventually wear off in time. It needs replacing every 12 to 18 months depending on how the jewellery is worn, to keep the white gold looking its best.
