about the materials


Gold: Each jewelry piece is created with the best quality material. For instance, 18k solid gold (marked as Au750) is made of 75% of pure gold and 25% of other metals. If you are ordering any fine jewelry piece in 18k white gold colour, it is important to know that we only make nickel-free white gold, so no more allergic reactions!

Silver: We only use 925 sterling silver or higher rated silver for our silver jewelry collection.


Diamonds: Diamonds are renowned for their beauty, which comes from their sharp visual brilliance and sparkle, to which cut, colour and clarity all contribute. We use collection colour diamonds ranging from G-H with a SI clarity to D-F with a VS clarity for the smaller stones. These are top quality stones with brilliant cut to create that sparkling natural shine. For the larger stones, a balance may need to be found between your budget and desire for size while making sure that the cut is excellent so that a very pretty and attractive stone is selected. We also provide GIA (Gemological Institute of America) certificate when you select a diamond that is greater than 0.5 carat.

Precious coloured stones: Sapphires and rubies are also sought after for their hardness although they are not as durable as diamonds. Emeralds are relatively soft. We hand pick only the best quality of these coloured stones to create our fine jewelry pieces.

about ordering

The process is simple: you browse around, find the piece you love, then place an order with the colour of gold of your choice (unless it's from the 925 sterling silver collection). We will get the exact style and size you ordered handcrafted right away. The wait time is between 4-6 weeks. Once we have your beloved piece made, we will express ship it right to your hands. 

If you are a creative individual and want to design your own jewelry piece, we offer custom made design too.
