Investments take a long time to show the results. Therefore, the people who have invested money in Diamond Investment have to wait a long term to see the results.

Diamonds lack many desirable attributes of diamond investment like liquidity, homogeneity and frangibility. Grading and certification of diamonds are done by recognized laboratories where there are some ways of redressing this. Weight and cutting proportions of diamonds are the main parameters, which can be measured. Color and clarity grades are the other parameters, which are required to be determined by the gemologists. The increasing quality, size and the decreasing price of synthetic diamonds gives a threat to the value of natural polished diamonds if considered for a long-term investment. These days the possibilities of low cost and ultra high quality diamonds are becoming available in the industrial qualities and quantities at some times in the future. The rise and fall in the prices of diamonds is caused due to the introduction of new stimulants, which are strongly undermining prices of natural gems and the permanent fall in natural diamond prices with introduction of cultured diamonds. Due to the altered supply and demand of diamonds in situation of overall prestige of the diamonds in general was lowered. Where synthetic diamonds are less socially acceptable to the market due to the natural version, arguably with the synthetic diamonds where the markets of natural and synthetic are separate, the prestige and value of the natural diamond investment has been retained with effort.

Diamond investment is considered as one of the "Most luxurious item a customer purchases to wear out or rot it".

Jewelries, but especially diamonds, last forever and have a more "intrinsic value" then cars and houses. Land too has an "Intrinsic value" and so do gold and diamonds have. Thus, the intrinsic value of diamond investment gives good returns and the growth can be seen at any time when you want to sell the diamond. The value of diamonds keeps on changing from time to time but it is not so frequent. The prices of diamonds continue to change throughout the year, as they do not have any kind of perfect season to buy. They are being purchased throughout the year, as occasions do not come due to the change in season.

Diamond Investment is considered as the steadiest investment among all sorts of investments, which prevail in the market. When a customer purchases a diamond, they do not think that it about the value and goodwill and they purchase it as an investment to act as a fixed asset at the time when the value of every asset falls down. Diamonds are considered as the investments, which can be sold anywhere in, the world as it has demand throughout the world. Thus if the owner is in immense requirement of cash then the owner will sell the diamond and will recover the price he has paid when he purchased it. Diamond Investment is considered as the investment, which never loses its value, as the diamond is never damaged due to anything. It may happen that the diamond may loose its shine but a certified person who is in practice of polishing diamonds can very easily do it. The diamond owner may keep a very close track of investments going on in the market and analyze the variations of prices so that he can earn the maximum profit on the diamond investment when the price is at its peak and it is not expected that the price will go beyond that in the near future.
