DOs and DO NOTs when buying a Diamond

By 23.09 September 20th, 2018 No Comments

Diamonds attract wealthy investors as hard asset investment commodities, as well as being bought by the public for jewelry items such as engagement rings. Should the latter be the area of your concern, then it is wise to know that usually men are concerned with the quality of a diamond, whereas women are concerned with size! The purchasing of a diamond can be a wonderful and exciting experience, so be smart and buy wisely. Keeping this in mind, take note of the dos and don’ts when buying a diamond, whether for a piece of jewelry or as an investment.

 

Dos

It is worthwhile to shop around to find an experienced supplier that suits your particular needs. Check the credentials of the supplier of your choice and look at various stones of similar shapes, sizes and qualities before deciding which one you want to purchase – compare ‘apples with apples’ first by comparing other suppliers’ stones. It is wise to view several stones at various suppliers before making a final purchase.

Your spend budget should be an amount that is affordable and will be dependent on the Four Cs of cut, color, clarity and carat weight. Teach yourself about the Four Cs which will determine the stone’s value. Differences in the various Cs can have a great impact on price, so do your homework first! Only pay an amount within your budget so that you are not put into debt.

The cut is the most important in order to maximise the amount of light coming through the stone. Clarity determines a major part of the value of the chosen stone. Color is personal, and should be of your preference, be the stone colorless or one the many colors available – the various grades of color will again determine the value. Carat determines the weight of the stone and subsequently the cost as well.

Ensure that you see the original certificate (not a copy) from a reputable independent gemology laboratory such as GIA (Gemological Institute of America), especially if purchasing a high quality diamond. Inspect the diamond under a 30x magnification microscope as this will show any flaws. A 10x magnification is not good enough for scrutinising flaws. Once you have seen the original certificate, and checked under the 30x microscope to see the flaws as well as the dimensions in mm, then check the weight. Only by checking these factors and verifying them yourself, can you be sure of the qualities of the stone of your choice. Also have the appraisal done in front of you before purchasing. Although an appraisal is for insurance value, it does not necessarily indicate its real market value.

If you are having the diamond/s set in a piece of jewelry, then watch the setting being done – in this way you are assured that no stone is being replaced by one of a lesser quality, size, color or carat weight.

Do nots

It is not advisable to buy a diamond from just any online jewelry store unless it comes from a trusted Diamond Advisor. You will have no idea of whether or not the supplier has good intentions and so many factors are deemed necessary when choosing a stone – know what these are before choosing a diamond.

When you have made a choice on your terms, think about this first – leave the supplier, think about your choice and only make the purchase when you are absolutely sure about the chosen diamond. Do not buy the first stone you see – shop around and act wisely and do not be fooled by sale or discounted stones.

Certification is imperative. If the diamond cannot be verified with a certificate, then do not buy it!

When buying diamonds, take cognisance of the Dos and Do nots and then your investment is assured of being a good one.

Cut

Nothing is more impactful on a precious stone’s brilliance than its cut. The cut refers to the angles and proportions of a diamond. Known in the industry as ‘fire’, referring to the coloured light reflected, and ‘brilliance’ for the uncoloured light. The cut of a diamond – its form and finish, its depth and width, the uniformity of the facets – determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light. A diamond should be cut proportionally, neither very shallow not very deep, given its dimensions. A diamond’s cut is its most important characteristics and a measure of its apparent beauty.

Certificate

A diamond certificate or grading report provides an expert opinion on the quality of the diamond and is provided by an independent gemology lab. Trained gemologists with specialized equipment measure the weight and dimensions of the diamond and assess quality characteristics such as cut, color, and clarity. Brilliant Earth diamonds are certified by the world’s leading gem grading labs including GIA, IGI, and GCAL.

Depth

The height of a diamond, from the culet to the table referred as a Depth of the diamond . Depth % is the height of the diamond as a percentage of the girdle diameter.

Table

Table referred as the largest facet of a gemstone, located at the top. Table % is the table width as a percentage of the girdle diameter.

Polish

Polish refers to the smoothness of the exterior of a diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and recommended by us for the finest quality jewelry.

×
Symmetry

Symmetry refers to the angles to which the facets are aligned. Basically exactness of the shape of a diamond, and the symmetrical arrangement and even placement of the facets. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Excellent, Very Good, Good, Fair, or Poor. We recommends diamonds with Good or higher symmetry grades.

×
Fluorescence

Describes the diamond’s response to ultraviolet light. In diamonds with strong or very strong fluorescence, there may be some interference with the flow of light which causes a milky or oily appearance. Canadian diamonds almost always have none to slight fluorescence.

×
Measurements

Diamonds with “fancy” shapes are measured according to their length, width and depth. These diamonds will have a longer axis (the biggest measurement) and a shorter one that represents their width. The depth indicates the measurement of the diamond from the bottom to the top. The relative proportions of a diamond ultimately affect its quality and value.

Round-shaped diamonds are never perfectly round even though they may seem to be that way when you look at them. There is a tiny variation between maximum and minimum diameter, so dimensions are reflected as measurements of maximum diameter, minimum diameter and depth.
