Silver in its natural state is a soft and delicate metal. In order to give the metal more durability in order to be used for jewelry it must be mixed with metal alloys that include copper for example. We mid pure silver with less than 7.5% alloy, making is sterling silver 925. Sterling silver has an endless application for fine jewelry and is made into rings, earrings, bracelets, necklaces, cufflinks and many more.


Gold metal is arguably to most beautiful precious metal in its natural form. Gold was amongst the popular precious metal for most jewelry, given its desirability. The standard measurement unit for Gold metal is Karat or K.

24K Gold – 24 of 24 parts Gold (100% Gold) – SOFTEST

18K Gold – 18 parts Gold with 6 parts other Alloys (75% Gold)

14K Gold – 14 parts Gold with 10 parts other Alloys (58.8% Gold) 10K Gold – 10 parts Gold with 14 parts other Alloys (41.7% Gold)

9K Gold – 9 parts Gold with 15 parts other Alloys (37.5% Gold) – HARDEST Alloys that are commonly mixed are copper and silver. 25% Copper is mixed with gold to make 18K Rose Gold (Pink Gold). On the other hand White Gold is made by mixing copper, zine and nickel or palladium.


Around the world Platinum is known as the most precious metal of them all, given its purity, rareness, and durability. It’s natural color gives the metal is elegant appearances, making it popular amongst bridal jewelry and high end jewelry. In order for the metal to be called Platinum, the metal must contain at least 95% pure platinum. Platinum is a hard metal that will never tarnish or wears out.

Diamond– Diamonds is easiest the most sought after type of gemstone. Diamond has a hard durable structure and its dispersion of light makes is desirable in any fine jewelry. The 4Cs help determine the quality or rather the grade of the diamond, which in turn is reflected on the price of the diamond. Clarity – Most diamonds have blemishes or imperfections which is often not visible to the naked eye. These blemishes are can naturally occur during formation of the diamond or when the diamond is cut, set or polished. The higher the clarity grade the less imperfection the more expensive the diamond is. A flawless diamond being superbly clear with no blemishes are the most desirable and the most expensive. Cut – A diamonds cut is just as important as it’s clarity. A good cut diamonds allows light to better disperse, bringing out its natural beauty. In addition to this a good cut diamond can also help conceal any blemishes and imperfections. While a poorly cut diamond can cause blemishes or imperfections making is look murky or dull. Carat Weight – A diamond’s weight is calculated in units Carat. The higher the Carat the heavier the diamond, the higher the price. Color – Diamond gemstone’s color ranges from colorless to yellow. The colors are graded by the Gemological Institute of America’s color scale which starts from D, being colorless to Z, being yellow.

Sapphire – When people hear the word Sapphire people generally think of the blue gemstones, but in fact sapphire is naturally available in green, purple, pink, yellow, orange and mixed colors.

Garnet – Garnet gemstones are compromised of closely related minerals, thus is available in a range of colors from orange to shades of green to pink. Red is the most common color for garnet gemstones.

Synthetic/Lab Grown GEMSTONES:

The Gemological Institute of America, commonly referred to as GIA describes synthetic gemstones as a material “that is made in a laboratory, but which shares virtually all chemical properties, optical, and physical characteristics of its natural counterpart”.

Cubic Zirconia – Often called CZ for short or Cubic. CZ is zirconia in its colorless form which gives it the appearance like of diamond. The flawless clarity (D color) and its ability to disperse light makes it very desirable. CZ is also available in a variety of colors. CZ is often used with silver jewelry to help keep the cost down. Working with CZ makes it easy for to source, control the color and control the clarity.

Nano Crystal Gemstones – Unlike CZ Nano Gemstones have a tolerate temperatures upwards of 1700℃; giving it several advantages. Nano gems can withstand the high temperature from castings process and cause no discoloration. In addition to this Nano Gems are readily available and make it easy to control the color of the stones.

Miki Siamese’s electroplating division can deliver customers with the highest finish on your pieces of art. We have a state of the art electroplating facility with a capacity of over 10,000 pieces a day.

Miki offers the following types of plating: Silver, rhodium, rose gold, yellow gold (14K Hamilton, 18K, 23K Colors), ruthenium. Plating in laymen’s term is covering or ‘coating’ that is applied onto a metallic surface.

There are many purposes to plating your jewelry:

  1. Prevent corrosion/tarnish/oxidization.
  2. Improve Solderability
  3. Reduce friction.
  4. Decorating and embellishing

Plating thickness– The unit of measurement we used to measure the thickness of plating is unit microns (μm). Miki Siamese’s standard for any silver jewelry is 1μm thick. However, rings for example, we recommend plating up to 3μm in order to prevent tarnish from the constant contact with other objects and to give it a enduring time of shininess. Miki Siamese can plate your pieces of art to which the desired thickness of our clients. We have the most advanced X-Ray machines to check of the correct thickness of plating.

Rhodium Plating– Rhodium is known as one of the most expensive precious metals in the world. Rhodium is a silver-white metal in the platinum family and is an inert metal; meaning its resistant to corrosion and oxidation. One benefit of Rhodium plating is that the metal is nickel free thus making it hypoallergenic. Rhodium plating allows for the most shine when compared to other plating. The application gives silver jewelry a deeper grey finish bringing out bright color stones, Cubic Zirconia or Nano Gemstones.

Silver Plating– Silver plating is when you apply a layer of 100% silver over the base layer; allowing your piece of art to endure a longer time of shininess. In addition to this it will enable extra protection against scratches and daily wear and tear.

Gold Plating– Gold plating involves the application of a Gold coating onto your piece of art through the process of chemical or electrochemical plating. Gold plating is an important application for making your pieces of jewelry look and feel more valuable. Gold plating can give silver jewelry the appearance and feel of gold jewelry.

Rose Gold– Rose Gold also known as Pink Gold is a mixture of Gold and copper alloy. The most common mixture of rose to gold is 75% Gold and 25% Copper, thus making 18K Rose Gold or Pink Gold. Given that copper is what gives Rose or Pink Gold its ‘pinkness’ it is not possible to have pure Rose Gold.

Ruthenium Plating– Ruthenium plating gives jewelry a more sophisticated/modern with the gun-metal/anthracite color look. Ruthenium provides a harder coating that is highly resistant to scratches and wear and tear.
