Diamond Education & Care
Diamonds are cut into many different shapes, each having its own unique sparkle & purpose.
The cut of the diamond determines how well it reflects light. When a diamond is well cut, the light is reflected from one facet to another, and is then dispersed through the top of the stone, making the diamond dazzling to the eye. However, if a diamond is cut too deep some of the light escapes through the opposite side of the pavilion, brilliance is lost, and the center of the diamond will appear dark. if a diamond is cut too shallow, light escapes through the pavilion before it can be reflected, again brilliance is lost and the diamond will appear glassy and dark.
Cut is the hardest aspect for any diamond cutter or polisher to master, however modern day certificates assist you in making the right decision. GIA (gemological institute of america) is the most respected of all diamond certificates and assesses cut ranging from excellent as the best all the way down to poor as the worst. we strictly work with excellent cut diamonds that have been hand picked to maximize brilliance. Hearts and arrows is a modern term commonly used by most industry workers for the public to view and see eight hearts from the back of a diamond, view from the culet. and eight arrows clearly showing, viewed from the table under a heart and arrow scope (a small device manufactured for that purpose). At La Bijouterie, we're Certified Diamond Graders from the Gemological Institute of America and the Diamond High Council in Antwerp. It is our duty to show you and explain to you why one diamond's cut is better than another.
Each and every diamond is one of a kind. No single diamond is absolutely perfect under 10× magnification (under a loupe), except for diamonds that have been graded 'flawless' by the Gemological Institute of America (GIA). These are extremely rare, so much so that most jewelers have never even seen one let alone sold one! The GIA clarity scale contains 11 grades, with most diamonds falling into the vs (very slightly included) or si (slightly included) categories. In determining a clarity grade, the gia system considers the size, nature, position, color or relief, and quantity of clarity characteristics visible under 10× magnification.The grades range from flawless to included as follows:
- flawless (fl) - no inclusions or blemishes are visible to a skilled grader using 10× magnification.
- internally flawless (if) - no inclusions and only blemishes are visible to a skilled grader using 10× magnification.
- very, very slightly included (vvs1 and vvs2) – inclusions are difficult for a skilled grader to see under 10× magnification.
- very slightly included (vs1 and vs2) – inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification.
- slightly included (si1 and si2) – inclusions are noticeable to a skilled grader under 10x magnification.
- included (i1, i2, and i3) – inclusions are obvious under 10× magnification and may affect transparency and brilliance.
Diamonds and other gemstones are weighed in metric carats. One carat is equal to 0.2 grams. A carat is divided into 100 points. For example, a 50-point diamond weighs 0.50 carats. however, two diamonds of equal carat weight can have very different values depending on the other factors (clarity, color, cut and other dimensions).
Diamonds are valued by how closely they approach colorlessness – the less color in the white diamond, then the higher the value. GIA's color grading scale for diamonds is the industry and international standard. the scale begins with the letter d, representing colorless, and continues with increasing color to the letter z, which is essentially light yellow or brown. each letter grade isn't an exact color, but it is a range of color. meaning a diamond of d color at the top of the range will be whiter, while a diamond near the bottom of the range will look more like an e color. It takes a diamond expert to distinguish these differences. White diamond engagement rings are the most sought after. if you are considering a white diamond, g-h color diamonds are most popular as they do not display a yellow tinge. i to j color diamonds could also look white under natural daylight (sunlight), and there are multiple ways that an expert designer can set the diamond in order to make any hint of yellow undetectable.
Taking Care of Your Diamond
At La Bijouterie, we offer a lifetime cleaning service to our customers. For the life of the ring, we will clean it in our ultrasonic cleaner as often as you like, we will also check the setting and make sure the diamond is safe and secure free of charge.
Our industrial strength ultrasonic cleaner zaps the dirt away at over 20,000 beats a minute. it is a very quick process and takes less than 30 seconds to remove all the oil and dirt. This is a complimentary service to all of our customers for life. Other cleaning options include the following:
The detergent bath is performed with a small bowl of warm suds using any mild liquid detergent such as dish soap. Immerse jewelry pieces in the suds and brush gently with a toothbrush. Rinse under warm running water and pat dry with a soft, lint-free cloth.
the quick dip method uses one of the liquid jewelry care products available. follow the instructions on the kit.
jewelry manufacturers and workshops use ultrasonic cleaning tanks. in these, the actual cleaning is performed by the cleaning solution, usually a mixture of ammonia and detergent, the ultrasonics merely provide the agitation to speed up the process. small domestic ultrasonic cleaners are now available, and many jewelry stores sell them as well. as our customer, you're always welcome to come in for a complimentary cleaning!
