Not all Cubic Zirconia or Lab Gemstones are of Equal Quality

Not all Cubic Zirconia or Lab Gemstones are of Equal Quality
Huge variations in quality are possible depending on how the cz gems are produced. Low-quality production methods can produce lab gems quickly and cheaply, often for under a dollar per carat;  but their quality, appearance and durability suffer greatly. Unlike their inferior counterparts, high-quality cubic zirconia stones and lab gems are created using superior base materials under exacting and time consuming laboratory conditions. While the cost of these high-quality synthetic gems may be higher, they are indistinguishable from the real McCoy without the aid of expert testing. Retail sellers may charge as much as several hundred dollars per carat for superior-quality cubic zirconia and lab gems; however, savvy cz buyers know they can purchase the same exquisitely created cubic zirconia gems from reputable online cz wholesalers like FU RONG GEMS for a mere fraction of their retail cost.

Loose cubic zirconia and lab created gems are created in the laboratory using two basic methods, either melt growth or solution growth. Melt growth is inexpensive but creates very low quality crystals. Melt growth is used to create the cheap synthetic gems used in class rings and discount store jewelry. Melt growth crystals lack fire and brilliance and have a “dead” look like a piece of colored glass.

Superior solution growth lab gems are more often created using the flux method, the method used to create the high quality cubic zirconia and lab gems sold online at Cubic zirconia Stones, lab ruby, lab sapphire and synthetic alexandrite crystals are formed in supersaturated chemical baths. The flux method used to create the loose lab gems sold by FU RONG GEMS produces the world’s highest quality cubic zirconia and lab gems. These manmade gems are virtually indistinguishable from Mother Nature’s own creations without the aid of a microscopic inspection and examination by a qualified expert.

In fact, high quality lab created gems like lab rubies and lab blue sapphires are created using the exact same chemical composition used by Mother Nature. FU RONG GEMS lab rubies and lab sapphires are created in the lab from synthetic corundum, just as nature creates these gems from naturally occurring corundum. Superior production techniques allow these lab created gems to be cut and polished exactly like natural gems and diamonds.
