Rose Gold

Homer, in the "Iliad" and "Odyssey," makes mention of gold as the glory of the immortals and a sign of wealth among ordinary humans.
The most noble of the noble metals, gold has been a valuable and highly sought-after precious metal for coinage, jewelry, and other arts since long before the beginning of recorded history.
Rose gold, is made from a gold and copper alloy. Since copper has a bold pinkish-orange color, adding this alloy to gold gives the gold a beautiful pinkish gold color. 18K rose gold contains 75% gold. 

Black Onyx

Onyx is a stone that appears in various cultures and it is regarded as one of the most popular gemstones in the world.
It is a type of oxide mineral that has dominant silica ingredients. The stone itself is famous for beautiful, silky luster that also looks vitreous if the stone is already treated and polished. Black colored onyx is of course the most famous and sought out variant. 

Onyx is also part of gemstone metaphysical theories and gemstone healing therapies.

Jade

With its beauty and wide-ranging expressiveness, jade has held a special attraction for mankind for almost 7,000 years.
Still today, this gem is regarded as a symbol of the good, the beautiful and the precious. It embodies the Confucian virtues of wisdom, justice, compassion, modesty and courage, yet it also symbolises the female-erotic.
It comes in many fine nuances of green, but also in shades of white, grey, black, yellow, and orange and in delicate violet tones. Only in the very finest jade is the colour evenly distributed.
