Real lab-grown diamonds have constantly offered the tantalizing prospect of making the wonder of true, real diamond affordable to jewelry lovers around the world. Unfortunately there is still a large hole between typical media articles and the reality of what diamond growing labs can actually grow as of December 2009.
This article is thus designed to educate diamond buyers who are interested in purchasing a real, lab grown diamond to ensure your expectations are realistic and know very well what is and is not available (and why). In addition, this article can help prevent you from being taken by underhand CZ sellers who advertise their product as ‘lab grown diamond’ or ‘man made diamond’ when their product is actually deceptively advertised CZ.
Since our last article in 2007, there’s been minimal progress 鑽石耳環推薦 on larger, lab grown white diamonds, though not for lack of effort by scientists. Buying a 2ct, real diamond grade, lab grown white diamond is currently about as likely as you discovering a unicorn… the reality is neither, as of December 2009, currently exist.
There are only two labs that have freely noted that they are working on growing white lab diamonds for the consumer market at this time. While one lab has had a few as large as 1ct, we were holding rare situations and not readily reproducible to date. Even with years of research and effort, the common diamond produced is less than. 50ct, and often the color is below the common diamond grade white mined diamond. The few that are available typically sell for the same price as or more than the usual comparable natural mined white diamond and wait times for larger sizes (. 75ct and higher) can exceed twelve months with no guarantee of if or when you will be able to purchase. Thus the truth remains that there is no diamond seller able to offer lab created white diamonds on a consistent, readily available basis and in sizes over 1ct (as of December 2009).
Because of this inequality between supply and demand for real lab grown white diamonds, it is possible to a number of CZ sellers who run ads, likely even showing next to this article, defining ‘Flawless Man made Diamonds’, ‘Perfect Lab Created Diamonds’ or similar false claims. These are underhand sellers peddling ordinary CZ under bait and switch advertising tactics. Their product is not actual lab grown diamond (carbon), but instead CZ (cubic zirconium), a accessible simulated diamond material that mimics the style of white diamond, but is not real diamond. Plain CZ has been available since the 1980s and is nothing new to the jewelry market. The only twist is how many sellers have prevailed in taking advantage of the consumers knowledge hole between media articles over-proclaiming the accessibility to real lab grown diamonds, and the limits of what truly is available in real lab created white diamond.
Lab grown blue diamonds are the one high point of the current lab diamond market. Natural mined blue diamonds are created when grown in the presence of boron, which is the reason their rare and unique blue color. Mined blue diamonds showing a rich, saturated blue color (Fancy Vivid Blue is the diamond term) of any reasonable size are very rare, and when available are nearly always sold via auction (Sotheby or Christies) in order for owner to obtain maximum value for what might be a once in a lifetime sale. As a result, natural vivid blue diamonds can command prices from $565, 000 per carat to often $1. 3 Million dollars per carat. A vivid blue diamond at auction is a media event, and regularly covered as a result by the press due to the extreme rarity, beauty and dazzling prices presented by mined blue diamonds.
Materials news for diamond lovers not on the Forbes 500 wealthiest list, is that as of two months ago, real lab grown blue diamonds are entering the market in sizes from. 50ct to often 1. 00ct. Supply is still quite tight, with an average of 5-10 Vivid Blues per month becoming available, but it is the first time this option has even been available on a regular basis. Just like mined blue diamonds, lab created blue diamonds are grown in the presence of boron in conditions identical as to the happens under the earth (high pressure and high temperature) and they are the chemical, optical, and physical equivalent — the only difference is where these were born.
The pricing on lab grown blue diamonds ranges from $5000/carat to often $10, 000/carat ($2500 is an average price for a. 50ct stone). Not cheap, but an incredible bargain in comparison to the pricing of the mined equivalent. One point of mentioning pricing here is to show the contrast between real lab grown diamond, and the CZ’s being sold as ‘lab grown diamond’ for $150/ct. $150/ct would not even cover the costs of cutting the material, and thus by pricing alone you can readily discern which sellers can market real lab created diamonds versus engaging in bait and switch advertising.
In terms of diamond beauty, while the chemical arrangement of both lab and mined blue diamond are identical (carbon plus boron), lab grown blue diamonds readily outshine their natural mined counterparts. The excuse is the cutting standards employed. Cut controls 98% of a diamonds brilliance, so because of this diamond beauty. Most basic blue diamonds are badly cut so that the blue coloration as rich as possible, and for the reality that cutting for optimal beauty (light handling) would cause a much smaller finished carat weight.
