Most man-made diamonds are used by industry, not by jewelers.
Without endorsement, you can review the site below to learn that gem-quality diamonds made by their patented process can be purchased up to 1.50 carats or 2.50 carats, depending on the colour that you want.
The marking "DIA 010" on a ring typically indicates that the ring contains a diamond weighing 0.10 carats. The "DIA" prefix signifies that the stone is a diamond, while "010" refers to the carat weight, where one carat is equal to 100 points. This marking helps potential buyers identify the quality and value of the ring based on its diamond content.

noSometimes jewelry manufacturers will stamp the inside of rings with numbers indicating the weight of a main diamond, especially a solitaire, for identification purposes. I have seen it done. Probably not a common practice though. If you have specific numbers stamped inside of a ring, list them here for possible interpretation.If there is an 8 digit number followed by another set of numbers, you are probably looking at the GIA number, which is usually followed by a 2nd set of numbers which is the carat size of the diamond associated with that number. For example 12345678 1.25 would mean you have a GIA certified diamond (Gemological Institute of America) weighing 1.25 carats. At least that is how my diamond is marked on the inside of my ring.NB: Since it is so easy to separate a diamond stone from the metal in which it is mounted, you can only trust the GIA certificate for a diamond stone as the true indicator of its value. Trusting the markings on the jewelry's metal to indicate the size/ quality of its diamond is naive..
The value of a diamond the size of an apple can vary significantly based on factors like its quality, cut, color, and clarity. However, a rough estimate for a large, high-quality diamond of that size (around 5 to 6 carats) could range from tens of thousands to several hundred thousand dollars. If it were a rare colored diamond, the price could skyrocket into the millions. Ultimately, the specific characteristics of the diamond will determine its final market value.
The value of a diamond is primarily determined by the "Four Cs": carat weight, cut quality, color grade, and clarity grade. Carat weight measures the size of the diamond, while cut quality assesses how well the diamond has been shaped and faceted. Color grade evaluates the presence of color, with less color being more valuable, and clarity grade considers the presence of internal or external flaws. Additionally, market demand and brand reputation can also influence a diamond's overall value.
The formation of gem-quality diamonds capable of yielding a finished stone weighing 1 carat or more is an exceedingly rare event. It is estimated that only about 1 in every million diamonds mined qualifies as a gem-quality stone of this size. This rarity is due to the specific geological conditions required for their formation, including high pressure and temperature over billions of years. Consequently, large, high-quality diamonds are highly prized in the gemstone market.
The biggest diamond in the world is the Cullinan diamond, which was found in South Africa in 1905. It is the largest gem-quality rough diamond ever discovered, weighing about 3,106 carats.
Depending on the cut, every diamond weighing two carats will have different dimensions. For example, a round brilliant cut diamond could measure about 8.2MM at the girdle. Its other dimensions depend on the quality of the cut.
The Cullinan diamond is famous for being the largest gem-quality diamond ever discovered, weighing over 3,100 carats in its rough form. It was cut into several smaller diamonds, with the largest pieces adorning the British Crown Jewels. Its exceptional size, quality, and historical significance contribute to its importance in the world of gemstones.
If by 'report' you mean a certificate from a gemologist, the import of this document certifies the quality of the diamond in terms of its clarity, colour, carat weight and excellence of its cut. Every diamond is unique, and especially with diamonds weighing more than one carat, a gemologist's certificate can reflect the monetary value of the gem.
what is quality of the finished project?
The biggest diamond on the Imperial State Crown is called the Cullinan II, also known as the Second Star of Africa. Weighing approximately 317 carats, it is set in the front of the crown. The Cullinan II, along with the Cullinan I, was cut from the Cullinan Diamond, the largest gem-quality diamond ever discovered.
Raw stones are mined from the earth, separated from the surrounding material, sorted/ graded and then sold/ brokered to diamond buyers. (Seventy-five percent of diamonds mined are employed in industry; only about 25% of mined diamonds are of gem quality.) Diamond buyers/ brokers then move the gem-quality stones to cutting operations, where the raw stones are evaluated for colour and clarity. Plans are developed to highlight the colour and clarity of each individual stone while preserving the highest carat weight. (About 60% of a raw stone's weight is lost in the cutting process.) Then the stones are cut and polished, and sold to brokers/jewelers who mount the finished diamonds into jewelry.
