Diamonds

Diamonds

The 4Cs

Every diamond is unique, but all diamonds share certain features helpful for comparison and quality assessment. These features are Color, Clarity, Cut and Carat Weight, also known as the 4Cs, developed by the Gemological Institute of America (GIA).

Cut

Cut refers to the arrangement of the stone's facets and the precision of the cuts, which affect its interaction with light. A well-cut diamond optimizes brightness (white light reflecting from the surface and interior), fire (flares of color) and scintillation (flashes of light seen when the diamond moves).

Color

Color does not refer to what color a diamond is, but to the amount of color in the stone. The closer to colorless a diamond is, the more desirable and valuable it is. Truly colorless stones are extremely rare; most diamonds used in jewelry are nearly colorless with faint yellow or brown tints. View Full Color Scale >

Clarity

Clarity measures the number and size of inclusions (internal) and blemishes (external), characteristics caused by the heat and pressure needed to form a natural diamond. The fewer of these characteristics exist in a diamond, the better its clarity grade on GIA's eleven-grade scale. View Full Clarity Scale >

Carat

Carat weight is the unit of measurement for diamond weight. A greater carat weight will generally mean a more expensive diamond. However, carat weight alone does not determine price or size; the stone's cut and shape affect how large the stone appears and, in addition to color and clarity, help determine value.

Certification

Some diamonds on Kohls.com may include a diamond certification issued by an independent and impartial gemological laboratory. The certification reports the quality and characteristics of the stone, ensures a diamond is natural and clearly discloses any treatments used to enhance color or clarity. It also includes a diagram of the diamond clearly showing the locations and types of flaws (inclusions) it has.

Conflict-Free Diamonds

Conflict diamonds are illegally sourced rough diamonds sold by rebel groups to fund military action against recognized governments. Also known as blood diamonds, conflict diamonds are most often from central and western Africa.

Pursuant to Kohl's Social Responsible Product Sourcing Policy, Kohl's requires our suppliers of diamonds and jewelry to ensure that the merchandise they sell to Kohl's meets the requirements of the Clean Diamonds Trade Act and the Kimberly Process Certification and that this merchandise does not contain conflict diamonds.

Care and Maintenance

Preserve the stunning state of your diamonds with proper care and maintenance.

Clean your diamonds at home every 2-3 weeks and professionally every 6-9 months. Exposure to skin oils, lotions, hairspray, household chemicals and other products causes buildup that dulls your diamond's brilliance. To clean at home:

  • Soak in a solution of warm water and ammonia overnight.
  • In the morning, scrub gently with a clean, soft-bristled toothbrush. Pay special attention to the back of the diamond as this will collect the most buildup.
  • Rinse and dry with a clean, soft and lint-free cloth.
  • An ultrasonic cleaner also may be used.

Inspect your jewelry frequently for loose or damaged settings. If you notice either, bring your piece to a professional jeweler immediately for tightening or repair.

Remove your diamond jewelry when doing rough work or playing sports; though diamonds are the hardest known substance, they can crack, chip or break with sufficient force. Also, remove your diamonds if you will come in contact with harsh or abrasive chemicals such as chlorine bleach, as these chemicals can erode or dissolve the metals used in settings.

Store each piece of diamond jewelry alone, as the jewelry can chip and scratch other pieces. A fabric-lined jewelry case with separate compartments or individual jewelry pouches are best.

Follow any instructions provided with your jewelry.

Pearls

Pearls

Types of Pearls

Natural pearls are the result of an irritant entering a mollusk's shell. To protect itself from the foreign substance, the mollusk secretes nacre to cover it. As layers of nacre are added, a pearl grows, usually in an irregular shape. It is quite rare to find a jewelry-quality natural pearl due to this irregularity.

Cultured pearls are produced the same way natural pearls are; however, the irritant is a shaped nucleus placed in the mollusk's shell intentionally. Because of the perfectly round base, cultured pearls are much more consistent than natural pearls.

Saltwater pearls are cultivated in the ocean, have a thinner layer of nacre than freshwater pearls and have a more brilliant luster. They are traditionally considered higher quality than freshwater pearls because of their luster, though new cultivation techniques are changing this conception. There are three common types of saltwater pearls.

  • Akoya pearls have the highest luster of all pearl types. They are cultured in the cool to temperate coastal waters of Japan and China. Colors include rose, silver/white, cream, gold and grey/blue.
  • South Sea pearls are some of the largest pearls available because they are created by Pinctada Maxima oysters, the largest pearl oysters in the world. Colors include silver, silver/pink, white, white/pink, white/gold and gold.
  • Tahitian pearls are grown in the French Polynesian native Black Lipped Oyster. Colors include peacock, black, black/grey, silver/grey, black/rose, blue/black, black/green and eggplant.

Freshwater pearls are grown in lakes, rivers and ponds. New farming techniques have yielded freshwater pearls with luster to match or exceed saltwater pearls. Colors include white, pink, peach, lavender, gray, yellow and cream. In addition, artificial dyes are used to produce any color desired.

What to Consider When Buying a Pearl

Pearl Size

Size

Pearls are measured by diameter in millimeters. Because large pearls are rare, they generally increase in price as they increase in size.

Pearl Shape

Shape

It is difficult to create a perfectly round pearl. The closer to round a pearl is the more expensive it will be.

Pearl Color

Color

Pearls can be found naturally in a wide variety of shades, and dye can be used to produce other vibrant hues.

Pearl Luster

Luster

The more lustrous a pearl the more beautiful and desirable it is. Luster is the reflective, luminous shine characteristic of a high-quality pearl.

Pearl Surface Quality

Surface Quality

Most pearls have slight imperfections because of how they are formed. However, a high number of such imperfections can take away from the beauty and durability of a pearl.

Pearl Nacre Quality

Nacre Quality

The thickness of a pearl's nacre coating helps determine its luster and durability. If the nacre coating is too thin, the pearl will have a dull or chalky appearance and the nucleus may be visible. A high-quality nacre coating will be thick and even.

Pearl Matching

Matching

Unless a piece of jewelry is designed to have different colors, shapes or sizes of pearls, the pearls in strands and other multi-pearl jewelry pieces should match as closely as possible.

Shapes & Settings

Shapes, Cuts and Settings

Shapes and Cuts

Asscher

The Asscher cut has step-cut facets and a square shape. It highlights the clarity of the stone, so a high clarity grade is important.

Baguette

A Baguette is a stone cut in the shape of a narrow rectangle with a faceted border. Baguettes are often channel-set or used as accents.

Briolette

Briolettes are faceted, teardrop-shaped gemstones. Traditionally, briolettes had triangle-shaped facets. Modern briolettes can be found with diamond-shaped and other facets. They are often found in earrings and pendants.

Cabochon

A Cabochon is a stone with a smooth, rounded surface and a flat bottom.

Cushion

The Cushion cut combines a square cut with rounded corners. This gives it a cushion-like appearance. Large facets highlight the stone's brilliance and clarity.

Emerald

Emerald cuts have long, rectangular, step-cut facets and a large, open table. This cut highlights the clarity of the stone.

Heart

Heart-shaped stones are a distinct symbol of love. Essentially a pear-shaped stone with a cleft at the top, heart-shaped stones lend beautiful sparkle to whatever piece they're set in.

Marquise

The Marquise shape, also called "navette," is an elongated oval with pointed ends. This long, narrow shape makes a stone look bigger than it really is.

Oval

An Oval-shaped stone has the fire and brilliance of a round stone, but has a distinct look. Oval-shaped stones are a popular choice because they accentuate long, slim fingers.

Pear

Pear-shaped stones are rounded on one end and have a single point on the other. The length of these stones has a slimming effect on the finger.

Princess

The Princess cut is a square-shaped cut whose unique look and beautiful sparkle make it a popular choice for engagement rings.

Radiant

The Radiant cut is a rectangular or square stone whose corners have been cut off. Because of its shape, a radiant-cut stone can be paired with baguette, round or square accent stones.

Round

Round stones are the most popular. The fire and brilliance of a round-cut stone makes it a breathtaking choice for solitaires and engagement rings.

Trillion

The Trillion cut is a triangular-shaped cut that typically has 44 facets.

Settings

Bezel

A Bezel setting consists of precious metal wrapped fully around the gemstone, holding it securely in place.

Cathedral

A Cathedral setting imitates cathedral architecture. It extends fully to meet the center stone on either side, providing extra protection and keeping the gemstone safe.

Channel

A Channel setting holds a series of gemstones by a slight rim of metal along the edges of the channel. Channel-set stones are usually round- or baguette-shaped.

Flush

A Flush setting is similar to a bezel setting; however, it is designed to make the inlaid stone even with (or "flush" with) the surface of the piece.

Invisible

An Invisible setting is one in which the stones are set closely together to give the illusion that they are one large stone.

Martini

A Martini setting is a setting that, when combined with the post backing, resembles a martini glass.

Miracle

A Miracle setting is a faceted setting designed to make the stone appear larger than it is.

Pave

A Pavé setting is comprised of small stones positioned close together and set apart by tiny beads of precious metal. Round-cut stones are commonly used.

Prong

A Prong setting holds the stone in place with a series of metal prongs.

Tension

A gemstone set in a Tension setting appears to be suspended in the air with nothing holding it in place. The gemstone is actually being held in place by a spring-loaded setting that exerts pressure on it.

Trellis

A Trellis setting is a type of prong setting. It has four prongs, with two prongs crossing each other on either side of the shaft.

Metals

Jewelry Metals

*Always follow care instructions included with your jewelry.

Gold

Gold

Pure gold is a soft precious metal resistant to rust, tarnish and corrosion. It is extremely malleable and often requires metal alloys like silver, nickel, zinc or copper to make it stronger and more durable. The ratio of pure gold to alloys is measured in karats (k); 24k gold jewelry is 100 percent pure gold.

Found naturally in yellow, the color of gold jewelry depends on the types and proportions of alloys used.

To care for gold jewelry, keep it away from harsh abrasives and clean it with warm, detergent-free soapy water and a soft-bristled brush.

Sterling Silver

Sterling Silver

Pure silver is an extremely soft precious metal. To create a strong alloy for use in jewelry, 92.5 percent pure silver is mixed with 7.5 percent of another metal, usually copper. This durable alloy is called sterling silver.

To prevent damage, keep sterling silver items away from household chemicals and out of chlorinated water. Polish sterling silver jewelry with a tarnish remover as necessary.

Stainless Steel

Stainless Steel

Stainless steel is a durable steel alloy made of chromium (at least 10.5 percent) and another metal. It is resistant to bending, breaking, tarnish, corrosion and rust. It is also hypoallergenic, ideal for those with sensitive skin.

To care for stainless steel jewelry, soak it in warm, soapy water and wipe it with a soft cloth. Do not use harsh abrasives.

Platinum

Platinum

The strongest of precious metals used in jewelry making, platinum is quite rare. Highly durable and dense, its color will never fade or alter. Most platinum jewelry is made of approximately 95 percent pure platinum.

To care for platinum jewelry, soak it in warm, soapy water and scrub it with a soft-bristled brush. To remove a patina, buff a platinum item with a soft cloth.

YellOra

YellOra

YellOra is a precious metal alloy that consists of 24-karat gold, sterling silver, palladium and proprietary metals. It offers the color and durability of traditional gold, plus it is tarnish-resistant and hypoallergenic.

Platina4

Platina 4

Platina 4 blends silver, palladium, platinum and gold for a metal that is both durable and beautiful.

Platinaire

Platinaire

Platinaire is a metal alloy that consists primarily of silver with some platinum and complementary metals. It is made from 97.5% recycled materials, is hypoallergenic and is nearly impervious to tarnish.

Tungsten

Tungsten

Tungsten carbide, an alloy made of 80 percent tungsten and 20 percent carbon alloyed with other metals, is extremely strong and has a high melting point. It is virtually scratch-resistant and tarnish-resistant. In addition, it is hypoallergenic.

To clean tungsten jewelry, use detergent-free soap, warm water and a soft cloth. Ultrasonic cleaners, steam cleaners and harsh abrasives should not be used.

Titanium

Titanium

Titanium, the hardest natural metal in the world, is very strong and lightweight. Pure titanium is hypoallergenic, perfect for those with sensitive skin.

To clean titanium jewelry, use window cleaner or liquid dish soap and water. Gently wipe away dirt and oils with a soft cloth. Do not use harsh abrasives.
