Cut describes the proportions and angles of a diamond. Many people confuse cut with the shape of a diamond. Although nature determines the other three characteristics, it takes a master diamond cutter to reveal a diamond’s true beauty. Diamonds are available in various shapes including round, square, pear, heart, marquise and oval but cut refers to the angles and proportions of a diamond.


A well cut diamond reflects light from one mirror-like facet to another and projects the light through the top of the stone. The result is a fiery and brilliant display. Diamonds that are cut too deep or too shallow leak light through the side or bottom, resulting in a lackluster appearance and diminished value.


Nature ensures that each diamond is as individual as the person who wears it. Naturally occurring inclusions such as minerals or fractures are identifying characteristics created while diamonds are formed in the earth. Master IJO Jewelers use magnification to view diamonds at 10x their actual size so these tiny inclusions are more easily seen.


Inclusions are measured on a scale of perfection, known as clarity, which was established by GIA. The greater a diamond’s clarity, the more rare and valuable it is. A diamond with an inclusion in the middle or top could impact the dispersion of light, making the diamond less brilliant. At Burque Jewelers, we make it our job to find you the perfect diamond within your budget with little or no inclusions in the table.


White-colored diamonds remain the most popular, even though diamonds are found in a kaleidoscope of colors. Diamonds are graded on a color scale implemented by the Gemological Institute of America (GIA), which ranges from D, which is colorless, to Z. Color differences can be so subtle that diamond colors are graded under controlled lighting conditions and are compared to a master set for accuracy. While truly colorless diamonds, graded D, are treasured for their rarity, diamond color is ultimately a very personal taste. Ask Burques Jewelers to show you an array of color grades next to each other to help you determine your color preference.


Carat Weight

Carat is a diamond’s measure of weight, not size. One full carat is equal to 100 points. A ¾ carat diamond is the same as 75 points. Since large diamonds are found less frequently in nature, a 1 carat diamond will cost more than twice a ½ carat diamond (assuming all other characteristics remain constant). The cut and the mounting can make a diamond appear larger than its actual weight. Burque Jewelers in Nashua NH will help you find the right diamond and mounting to optimize its beauty.

Jewelry Care

GOLD: Gold jewelry should always be taken off before showering, since soaps can build up a dull film on gold.

STERLING SILVER: Sterling silver will polish up by rubbing or buffing it with a soft cotton cloth or a Sunshine Cloth. Silver stored in plastic bags with an interlocking seal will be less prone to tarnish.

PLATINUM: Platinum jewelry can be cleaned by using a specifically designed jewelry cleaner, or you can have us at Burque Jewelers clean and polish your platinum.

PEARLS: Do NOT store pearls in plastic bags! Pearls require a certain level of moisture in storage. Check with us at Burque Jewelers for the best long-term storage options if you know you won’t be wearing your pearls often.

To protect your jewelry, always take care to shield pieces from scratches, sharp blows, harsh chemicals, extreme temperatures and sunlight. Make certain to carefully store any fine jewelry, and store each piece separately, so it can’t scratch other pieces.

When doing household tasks such as gardening and cleaning, remove your rings.

Put your jewelry on after washing and applying any makeup or hair spray.

Never wear jewelry while swimming in a swimming pool or when using chlorine bleach. In addition to damaging the gold by making it brittle, chlorine can cause damage to various gemstones and gold settings which may cause them to become loose and fall out.

Avoid keeping your jewelry next to a heating vent, window sill or on a car dashboard.

Store jewelry away from sunlight as the sun may fade the gemstones.

If you have bead necklaces, such as lapis or pearls, store them flat because silk stretches over time. Burque Jewelers’ repair department will restring necklaces or reset stones. If you wear your bead/pearl necklaces regularly, have them restrung by us at Burque Jewelers once a year.

Hardness is based on a gem-trade standard called the Mohs scale. The scale goes from 1 to 10 and the higher the Mohs scale number, the harder the stone is. Diamonds are a 10 on the Mohs scale. Anything with a Mohs scale rating of less than 7, such as coral, lapis lazuli, opal, pearl, and turquoise, is easily scratched. Gold, silver, and platinum are only Mohs 2.5 to 4.

Be certain that stones mounted in rings are not loose or rattling in their setting. The prongs of a ring can and will wear down. If the prongs wear down too much or even break, you risk losing your gemstone(s). Prongs can be easily “retipped” by Burque Jewelers’ repair department to keep the stone(s) secure.
