Diamond Cut

CUT

Many people confuse cut with the shape of a diamond. The shape you select is a matter of individual taste, and today your choice is only limited by the skill and imagination of the craftsman.

The cut is the most critical component of the 4 C’s, since the value of two diamonds with exactly the same carat weight could vary by up to 30% depending on the quality of cut. Just as fine cloth needs an expert tailor to create a quality garment, the diamond cutter controls the fire and brilliance of a diamond.

The cutting grade is determined by the diamond cutter’s effort to maximize the refraction of light during every stage of the fashioning process. Most brilliant-cut or fancy-shaped diamonds possess fifty-eight carefully angled flat surfaces, called facets, whose placement will affect the fire, brilliance and ultimate beauty of your diamond.

DIAMOND COLOR SCALE

COLOR

Prized diamonds are color-less. Their beauty depends entirely upon their remarkable optical properties. All the colors of the rainbow are reflected back to your eye. Though most diamonds appear to be icy-white, the fact is that most diamonds have slight traces of color, usually yellow or brown. The most valuable is no color, or colorless, due to its rarity. With each subtle departure from colorless, there is a decrease in rarity and value. The GIA color grades range from D (colorless) all the way to Z (yellow-brownish).

CLARITY

CLARITY

Clarity in a diamond is defined by the presence of natural characteristics. A diamond is graded using a microscope at 10 power (10x) magnification. The most rare and valuable diamonds have no natural characteristics at 10 power, and diamonds with more and larger characteristics are less rare and less valuable. As with color, differences in clarity can be very subtle, yet have a decided impact on value.

CARAT

Carat weight is the standard unit of weight for diamonds. One carat equals 1/5 of a gram, or .007 of an ounce. Carat weight is further divided into decimals. For example, exactly 1/2 carat is .50 carat and expressed as 50 points. Because diamonds are weighed to hundredths of a carat, they must be weighed on extremely precise and sensitive scales. All other factors being equal, as weight increases, so does rarity and value.

General Jewelry Care

  • Keep your fine jewelry items from contact with one another to avoid abrasion.
  • Keep your jewelry looking new by cleaning it regularly. Soap and oils from fingerprints can significantly detract from the beauty of your diamonds and fine jewelry.
  • Apply makeup and cosmetics prior to putting on your jewelry. Chemicals in these substances can often harm the look of your gold and damage pearls.
  • Avoid wearing jewelry in swimming pools. Chlorine can react with metals causing color and structural damage.
  • Fine jewelry items should not be worn while engaged in activities where they would be subject to any form of brushing or hard contact. A strong blow from the side could dislodge a gemstone from its mounting. If you decide to wear your jewelry while gardening, please exercise caution.
  • Cultured pearl necklaces should be strung with knots between each bead. Please keep all pearls away from hair spray, perfume, and cosmetics.
  • It is recommended that all jewelry be inspected semi-annually or after any sharp blow to stones or mounting.

Ultrasonic Cleaning 

 Diamond, Ruby, Sapphire, Amethyst, Citrine, and Created Gemstones – Ultrasonic cleaning machines are perfect for these gemstones. Please be sure to keep items from touching one another while cleaning. Check all stones after cleaning for a tight fit in the mounting. If you do not have a cleaning machine, commercial jewelry cleaner solution or water mixed with a small amount of dish washing soap works fine with a soft cloth or brush to remove any fingerprints. Gemstones that are not translucent, such as pearls, opals or onyx, should, as a general rule, not be cleaned in an ultrasonic cleaner or cleaned with an abrasive or ammonia based cleaner.

Gem Stone Care

AMETHYST

Amethyst, like its cousin, Citrine, is an extremely durable stone that will withstand normal cleaning, but avoid direct heat.

AQUAMARINE

Do not use an ultra-sonic machine; avoid heat as it may cause discoloration.

BLUE TOPAZ

Care should be taken when cleaning a topaz of any color. Do not use an ultrasonic machine. Avoid prolonged exposure to light and heat, as well as sharp blows or sudden temperature changes.

CITRINE

As quartz, citrine is able to withstand normal cleaning but avoid direct heat.

EMERALD

Because emeralds are oiled and usually included to some degree, this stone should not be placed in an ultrasonic cleaner. Emeralds should be cleaned gently with a small brush and lukewarm water. Avoid sudden temperature changes and sharp blows.

GARNET

Garnet is an extremely durable stone and therefore will withstand normal cleaning.

OPAL

Opal is a soft stone that requires care when cleaning. It should not be placed in the ultrasonic cleaner, nor should you use an ammonia based cleaner on the stone. Clean with a soft cloth or occasionally a combination of a mild non-detergent soap (such as Woolite®) and warm water with a soft brush.

PEARL

After each wearing, clean with a soft cloth. Periodically clean with very mild non-detergent soap (Woolite®); lay pearls on a clean towel and dry completely before wear. Never use ultrasonic or steam cleaners. Use only commercial jewelry cleaners that are made specifically for pearls. Avoid contact with perfumes, cosmetics and household cleaners, and return your strand to your jeweler for periodic professional cleaning and restringing.

PERIDOT

Do not use an ultra-sonic machine. Avoid sharp blows and sudden temperature changes

RUBY

Rubies are fairly durable stones; however, the filling process often used on rubies requires special care when cleaning the stones. This enhancement technique may wear over time if treated harshly or exposed to strong solvents or abrasives. Avoid direct heat.

SAPPHIRE

Because the heat treating process used is permanent, sapphires are an unusually durable stone. Normal care in cleaning is used, but avoid direct heat.

TANZANITE

Clean with mild soap and water; do not use an ultrasonic machine. Avoid sudden temperature changes and sharp blows.
