Marquise Cut Diamonds

We have the largest stock of GIA certified loose diamonds in Australia. Being diamond wholesalers means that we can offer the lowest prices for GIA certified diamonds in Australia.

We are the ONLY Australian jewellery store to offer a 30 day easy returns and money back guarantee on all diamonds purchased from us. We are extremely confident and guarantee that we will never be beaten on price on a GIA certified diamond.

We are also the ONLY diamond wholesalers in Sydney and Melbourne to offer a lifetime upgrade guarantee. This means that if you ever (even after 10 years) would like to upgrade from a 1 carat diamond to a 2 carat diamond, you get the full value (the money you paid) for the 1 carat diamond and pay only the difference. This means that you never ever lose money on your diamonds when you buy from Temple and Grace.

Call us on 0414 500 999 for a no-obligation quote. We guarantee Australia’s LOWEST prices and FREE 30 day returns on any GIA certified loose diamond.
