Our Materials

MOI is soulful luxury. It is meant for everyday and forever! We only work with high-quality, enduring materials, from precious metals to genuine gemstones.

Precious metals 

The metal of royalty, gold has long been coveted for its reddish gold sheen and resistance to oxidation or corrosion. Although rare, gold is a highly malleable metallic element and is found throughout the world. Pure gold is very soft, so it's alloyed with other metals like copper, silver, and zinc to create the 14 karat gold that we use. This means that 14 out of 24 parts are gold, giving you the ideal balance of luxurious color, bright shine, and long-lasting strength. 

14 Karat Gold : 14K gold with 58.4%(14 out of 24 parts) gives a subtle hue to the pieces and tightly holds and secures the diamonds and gemstones. It is appropriate for everyday-wear; scratches less and doesn’t bend or wear out easily.

18 Karat Gold : purity though seldom used in our designs is also appropriate for everyday-wear but we prefer to use 14K gold for its strength in holding the gemstones in place.

22 Karat Gold : 22K gold has 91.67% (22 out of 24 parts) purity and is mostly used in our designs that use the kundan setting (see glossary).

24 Karat Gold : 24k gold has 99.9% purity, is technically a gold foil as it is the purest and hence the most malleable. It is only used in our designs that use the kundan setting (see glossary).

925 Silver : The extremely ductile 925 Sterling Silver is an alloy made of 92.5% pure silver and 7.5% copper.

Diamonds  

The Four C's of Diamonds, Cut, Color, Clarity, and Carat, are the basics that are used to select and grade all diamonds.
The different cuts and colors of Diamonds we use are : 

Brilliant-cut Diamond : Can you think of a better name for the sparkling look of the brilliant cut? With a precise arrangement of 57 facets, the brilliant cut is the benchmark for white diamonds. These stones represent the pinnacle of the gem cutter's art and bring unmatched brightness to any setting.

Rose-cut Diamond : A throwback to the centuries-old cut, the simple and stunning rose cut was the jeweler's cut of choice for hundreds of years. Unlike round brilliant cuts, the rose cut is flat on its bottom with a domed surface, giving any setting an architectural beauty and creating a more subtle and understated sparkle. It is usually round but sometimes oval too.

Single - cut Diamond : Also called “Melee” diamonds, these are cut as round brilliants but have fewer than the standard 57 or 58 of facets are referred to as “single cut”.

Baguette-cut : Often used as accent stones, baguette-cut gemstones are long and rectangular with octagonal corners. A baguette-cut diamond will generally have less brilliance than a traditional brilliant cut. It became popular during the Art Deco era, which favoured straight, geometric patterns and forms. It is one of the more expensive diamond shapes as more of the stone is lost to create the shape than with other cuts.

Marquise-cut Diamond : A modified brilliant cut, the Marquise cut looks a little like a football. Symmetry is critical to the marquise cut, and even a slight misalignment of the two end points or right and left sides can cause it to appear off-balance in jewellery design.

Princess-cut Diamond : Betzalel Ambar and Israel Itzkowitz created the popular princess cut in 1980. A square cut, these diamonds are flexible and work well in nearly any ring style.

Champagne Diamond : Though white is the most famous, diamonds actually occur in lots of colors and champagne is one of our favorites. Naturally brown with a yellow tint, these diamonds add extra romance to our designs. Best of all, you get all the virtues of a natural diamond like superior hardness and incredible fire.

Sliced Diamond : Diamond slices are thinly sliced sections of a larger diamond piece, each cut in their own particular shape, which can be oval or irregular.

Uncut Diamonds/Polki/Vilandi : A diamond that has few facets and appears to have little fire or brilliance. It refers to unpolished or rough diamonds. Polkis can be irregular in shape and are frequently used in the Indian setting technique of kundan.(which is essentially gold foil- see kundan in glossary)

Gemstones 

Agate : A semiprecious gemstone, agate is a variety of quartz and usually features bands of colour that vary from tan to red or brown to green. Agate is an umbrella name for a number of varieties of banded chalcedony. Agate crystals occur in many colors that range from translucent to opaque.

The earliest emeralds came from Zimbabwe and are among the oldest known gemstones in the world. Today, top-quality emeralds are mined in Colombia.

Emerald Doublet : A doublet is a gemstone that is composed of two parts; usually a valuable gemstone material at the crown(top) and a less expensive material (synthetic sapphire, quartz or glass) in the pavilion(bottom).

Pearls

South - Sea Pearls : South Sea Pearls are very rare and unique. Given the rarity of the oyster, cultivation and production costs remain extremely high. Also the reason why South Sea Pearls are among the most expensive pearls. South-sea pearls have naturally occuring imperfections and indentations. Pearls may have surface damage, imperfections, cracks or chips in their nacre.

Tahitian Pearls : More rare than white pearls, black pearls come from the giant black-lipped oyster called the Pinctada Margaritifera. These iridescent pearls range in colour from deep midnight black to shimmering emerald green and pale silver blue. Although black pearls are found in various oceans around the world, Tahitian black pearls are particularly renowned for their sheen and beauty. These pearls derive their name from the fact that they are primarily cultivated around the islands of French Polynesia, around Tahiti.

Mother of Pearl : Also known as nacre, mother-of-pearl is the iridescent layer that forms inside the lining of many molluscs, including pearl oysters and abalone. It comes in many natural colours but is often bleached or dyed. We have also used a colored mother of pearl.

Cultured Pearls : These pearls are created by a mussel farmer or oyster farmer under controlled conditions.

Chinese Button Pearls : Chinese button pearls are symmetrical button-like pearls that appear to be flattened or squashed to some degree.

Freshwater Pearls : Freshwater pearls come from freshwater mussels. Freshwater pearls come in an amazing variety of shapes and colours.
