The purity or fineness of gold is measured in karats. Pure gold is incredibly soft, so gold jewellery is generally alloyed, or mixed, with metals such as Silver, Copper, Nickel or Zinc.

24 karat gold (24k) is considered pure Gold and is incredibly soft and malleable. It has a fineness of 999.9 per thousand parts of Gold. Jewellery pieces are not often made with 24 karat gold because they would not be durable. However, since it is soft, it is sometimes used in plating other base metals which results in a radiant finish.

18 karat gold (18k) is an alloy composed of 75% gold and 25% other alloys. It has a fineness of 750 per thousand parts of gold. This means that the other 250 parts are alloy metals. This is an excellent purity of Gold for creating jewellery as it combines pure gold with just enough alloys to allow durability.

14 karat gold (14k) is composed of approximately 58% Gold and 42% other alloys. It has a fineness of 583 per thousand parts of Gold. This is the most popular purity of gold due to its balance of beauty and affordability.

Other karatage’s of gold can be alloyed to meet market preferences.

We at Diseno Jewels provide you with an option of 18k and 14k gold for optimum appeal, durability and affordability.



Silver is an incredibly soft and malleable in its purest form, so it is often alloyed with copper in addition to other metals in small amounts to add strength and durability.

Fine Silver has the highest concentration of Silver: 99.9%. Although its shine is remarkable, its strength is limited. Jewellery made with this purity of Silver should not be worn daily.

Sterling Silver (abbreviated as SS) is a mix of 92.5% pure silver and 7.5% other metals. Its fineness being 925 parts per thousand. Sterling Silver is the most common silver alloy used in jewellery making.



Platinum is an extremely dense and strong precious metal, which makes it the best choice for durability, longevity, and beauty. Moreover, it is hypoallergenic, so even people with sensitive skin can wear it. For jewellery to be labelled platinum, it must be made of at least 95% platinum metal, that is, fineness of 950 parts per thousand. Any piece of jewellery containing less than 95% platinum must include a label describing the parts per thousand of platinum present in a piece. For instance, a piece containing 90% platinum, which is the equivalent to 900 parts per thousand of platinum, will be labelled 900 platinum (900 plat or 900 pt.). Due to its excellent hardness, this metal is preferred for setting diamonds in a remarkably secure setting.



Hallmarks are official marks used in many countries as a guarantee of purity or fineness of precious metals and jewellery. Hallmarks consist of a brand logo along with the metal karatage which aids as information of the product you are purchasing- who made it and what is its guaranteed standard of fineness. For example, an 18k piece of gold will be stamped with 18k or 750 to indicate its purity. Likewise, a 14k piece of gold will be stamped with 14k or 583, and Sterling Silver with 925 or SS 925.

We at Diseno Jewels laser mark all our products with our logo along with the metal karatage you choose to purchase as per the Bureau of Indian Standards (BIS). The BIS Hallmarking Scheme has been aligned with International criteria on hallmarking. This guarantees you a product of credible standard.


Visual Appeal

Gold in its natural form is yellow. The two most popular alternate colours are White Gold and Rose Gold, both measured in the same karat weights as Yellow Gold.

White Gold is comprised of Gold that has been alloyed with white metals—usually nickel or palladium—to create its colour.

Rose Gold is created by mixing gold with copper which is responsible for its pink colour along with lesser amounts of white-coloured metal alloys. Because Rose Gold contains copper, it will develop a deeper, more intense colour over time.

Silver in its natural form is a white metal, as also, is Platinum. However, Platinum has a grey tinge to it which is why this metal is often plated with Rhodium to give it a whiter, shinier finish.



Although polishing causes the metal to shine giving it a mirror-like finish, many jewellers opt to plate certain metals to enhance its lustre or for aesthetic appeal. Most often when jewellery is made with non-precious base metals like copper or brass, they are plated with a thin layer of Gold or Silver, known as “flash plating”, to give the metal a more luxurious feel. Similarly, with Silver jewellery, the pieces are either plated with a flash coating of Gold (Yellow or Rose) or a thicker layer of plating known as Vermeil plating. Silver can also be plated with Rhodium, a durable white metal with high lustre. Rhodium plating is almost always used to plate White Gold and Platinum pieces. In addition to plating the entire jewellery piece, plating is also used to enhance the way gemstones look in jewellery or for a dual metal tone effect. For example, areas around white diamonds are Rhodium white, to bring out the sparkle of the diamond. Similarly, jewellers chose to plate the setting areas of darker gemstones like sapphires or black diamonds with Black Rhodium to enhance it.

To summarize, selecting a metal for your jewellery piece depends on your budget and colour preference. Choosing a metal that compliments the stones set in it and your skin tone is an added benefit. To learn more, visit out blog page and education centre for care, cleaning and storage tips.
