A diamond heart shaped pendant's value is based on four criteria: color, cut, clarity, and carat. The clarity and color of a diamond heart shaped pendant usually are graded. However, scales are not uniform: a clarity grade of "slightly included" may represent a different grade on one grading system versus another, depending on the terms used in the scale. Make sure you know how a particular scale and grade represent the color or clarity of the diamond heart shaped pendant you're considering. A diamond heart shaped pendant can be described as "flawless" only if it has no visible surface or internal imperfections when viewed under 10-power magnification by a skilled diamond heart shaped pendant grader. As with other gems, diamond heart shaped pendant weight usually is stated in carats. diamond heart shaped pendant weight may be described in decimal or fractional parts of a carat. If the weight is given in decimal parts of a carat, the figure should be accurate to the last decimal place. For example, ".30 carat" could represent a diamond heart shaped pendant that weighs between .295 - .304 carat. Some retailers describe diamond heart shaped pendant weight in fractions and use the fraction to represent a range of weights. For example, a diamond heart shaped pendant described as 1/2 carat could weigh between .47 - .54 carat. If diamond heart shaped pendant weight is stated as fractional parts of a carat, the retailer should disclose two things: that the weight is not exact, and the reasonable range of weight for each fraction or the weight tolerance being used. Some diamond heart shaped pendants may be treated to improve their appearance in similar ways as other gemstones. Since these treatments improve the clarity of the diamond heart shaped pendant, some jewelers refer to them as clarity enhancement. One type of treatment - fracture filling - conceals cracks in diamond heart shaped pendants by filling them with a foreign substance. This filling may not be permanent and jewelers should tell you if the diamond heart shaped pendant you're considering has been fracture-filled. Another treatment - lasering - involves the use of a laser beam to improve the appearance of diamond heart shaped pendants that have black inclusions or spots. A laser beam is aimed at the inclusion. Acid is then forced through a tiny tunnel made by the laser beam to remove the inclusion. Lasering is permanent and a laser-drilled stone does not require special care. While a laser-drilled diamond heart shaped pendant may appear as beautiful as a comparable untreated stone, it may not be as valuable. That's because an untreated stone of the same quality is rarer and therefore more valuable. Jewelers should tell you whether the diamond heart shaped pendant you're considering has been laser-drilled. Imitation diamond heart shaped pendants, such as cubic zirconia, resemble diamond heart shaped pendants in appearance but are much less costly. Certain laboratory-created gemstones, such as lab-created moissanite, also resemble diamond heart shaped pendants and may not be adequately detected by the instruments originally used to identify cubic zirconia. Ask your jeweler if he has the current testing equipment to distinguish between diamond heart shaped pendants and other lab-created stones.
