A. The Why Buy From Us section of our website should answer this along with many other relevant questions -- you can also contact us with more questions/concerns if still in doubt, and we will make sure to address all that is asked.
A. We stand behind every single item we sell, simply because we understand that reputation takes years to build, however, it takes only a moment to be demolished, and not restored! With our Lifetime Warranty, you can rest assured that you will receive the value and product/service you expect, or better!
We can also provide Appraisal Certificates for any piece of jewelry you desire for a nominal fee. An appraisal certificate is usually an estimate of the approximate retail replacement value of the jewelry, which may be used for insurance coverage or other purposes. The appraisal certificate contains information such as an accurate description of each article of jewelry being appraised, an image, and the appraised value.
A. We work with small profit margins due to the minimal budget set aside for marketing & advertisement -- the majority of our customers find us by word-of-mouth and verbal referrals - we pay you to refer a friend! -- we monitor & maintain low overhead costs of one physical store and online business operations -- our professional & experienced sales & service staff receive no commissions based on sales; instead, they receive incentives for maintaining a loyal customer base -- our prices are low also because some products are designed and manufactured in-house, allowing us to provide the most affordable and the lowest prices.
We also negotiate the lowest possible prices with our trusted/dependable jewelry & watch merchandising vendors, the brand manufacturers, along with diamond & color gemstone network of dealers -- if there is an opportunity to save money while maintaining high-quality standards & promised delivery, be sure that we will take it, and pass it along to you!

A. Yes, we ship each item of value in a beautiful individual presentable jewelry box.
A. Yes, we do. Please contact us and we will be more than happy to provide the jewelry service you need.
A. A cautious yes! Just make sure that you give your jewelry to an expert jeweler for repair -- emphasize the type of material (10k, 14k, 18k, platinum, sterling silver, an alloy, etc.) to your jeweler so that they do the job utilizing the same base material as the ring -- also disclose to your jeweler any kind of known treatment (if any) on the gemstone(s).
If the ring is made in “Invisible Setting” or “Tension Setting” or any other kind of specialized setting, it is essential to ensure that the intended jeweler is particularly experienced and equipped to handle the resizing job properly -- you are always most welcome to bring your ring to us (or mail it) and our expert jewelry craftsmen will properly resize it for you.
A. No, we are not an authorized dealer for any of the watch brands we sell -- however, we work closely with a network of authorized watch dealers and thus can quickly locate name brand watches at a discount directly from our trusted network. Contact us for availability & pricing.
A. We can most certainly provide loose gemstones and jewelry items certified by laboratories such as AIG, GIA, EGL, local labs, etc. -- however, there is an additional cost involved in having the stones safely mailed to the laboratory and certified.
We do a lot of business with AIG Gem Laboratory (American International Gemologists) -- cost for AIG certification range anywhere from $100 to $500 (or more) depending on the complexity of the item being certified -- GIA certified gemstones are usually priced roughly 20% more than uncertified stones -- EGL certified gemstones are priced roughly 10% more than uncertified stones.
Having the stones certified by our local recognized laboratory is the least expensive option -- due to the costs and time involved in having the stones certified, in our experience, and based on customer requests, we find that usually, people do not tend to request certification for low-grade color gemstones, and single diamonds weighing 1 carat or less.
A. There are other lower-cost alternatives, contact us for expert advice.
A. Yes, there are -- we recommend the following alternatives in the following order: 1) Lab-Grown Diamond, 2) Moissanite, and 3) Cubic Zirconia.
A. For example a ring with one 1.00 carat colorless, top quality diamond can be worth more than 10 times as much as a ring with several small diamonds of 1.00ctw. (total carat weight) of the same quality -- this is because the supply of larger single diamonds is very limited and therefore the price is higher -- to get an idea about variations in price as related to size and quality, we suggest looking through the Loose Natural Diamonds, Loose Lab-Grown Diamonds, and Loose Moissanite pages of our website.
A. Platinum is a white precious metal used in jewelry settings or watch casings and watch bands. It is important to note that Platinum is not white gold. Platinum is naturally white whereas white gold is created from yellow gold by adding nickel, copper, zinc, and sometimes silver.
Platinum resists corrosion and does not tarnish. Platinum is harder than gold and silver, so it outwears them. Its hardness is about the same as Iron (4-4.5 on Mohs’ hardness scale). Platinum is very heavy and dense compared to other metals. it is approximately twice as heavy as silver, about 1.65 times heavier than 14k gold, and 1.4 times heavier than 18k gold.
Because of its strength and density, Platinum holds diamonds very securely and has high resistance to wear. This is why Platinum prong settings are sometimes used on gold rings and why estate jewelry made of Platinum often looks relatively new after many years of wear.
Platinum is very rare, even more so than gold. Over 20 times more gold and over 12.5 times more silver are produced annually. Approximately 95% of all Platinum supplies come from South Africa and Soviet Republics.
Platinum normally costs more than pure gold on monetary market exchanges. The high purity of Platinum jewelry (90%-95%) compared to 14k and 18k gold jewelry (58%-75%) is another reason why platinum is more expensive.

Precious Metals - Quick Reference Chart
A. First and foremost, it is important to know that Lab-Grown Diamonds are NOT synthetic imitation stones (such as cubic zirconia, zircon, white sapphire, Swarovski, glass, spinel, Diamonique, etc.) NOR diamond simulants (such as moissanite, etc.).
In simple words, Lab-Grown Diamonds are the same as diamonds, but much cheaper because instead of being formed naturally in Earth's mantle (and then delivered to the surface by deep-source volcanic eruptions), they are developed in a laboratory (man-made) under similar environmental conditions as natural diamonds. For this reason, Lab-Grown diamonds are considered to be the only non-simulant and conflict-free alternative to natural diamonds because they possess identical chemical, physical, and optical properties as natural diamonds originating from nature.
Both Lab-Grown and naturally mined diamonds have the same chemical composition and atomic structure, producing the very same durability, fire, and sparkle. Laboratory-grown diamonds are truly a testament to the use of technology and human achievement.
Getting more into the science, "Lab-Grown" most accurately describes the man-made production process in which the crystal structure is grown from the "seed diamond". Lab-Grown diamonds are the result of an extemporaneous crystallization process rather than a synthesis of compounds. Lab-Grown diamonds utilize a Chemical Vapor Deposition (CVD) process or a High-Pressure High Temperature (HPHT) method that causes carbon atoms to crystallize into the structure which renders them harder than any other form of carbon and harder than any other material.
Both processes require advanced technological equipment and both produce rough diamonds that are then cleaned, cut, and polished in the very same way that naturally occurring, mined diamond rough is processed. Diamond growth can be initiated only when a pre-existing diamond seed or a sliver of the diamond substrate is present for the carbon atoms to attach to and “learn” the diamond’s strong tetrahedral crystal lattice. The “seed” essentially serves as a blueprint for the crystallization process as carbon atoms stack one by one on the carefully selected seed.
Lab-Grown Diamonds are graded to the same carat, clarity, color, and cut specifications as mined diamonds and they can be accompanied by the same type of Diamond Grading Reports written by leading independent gemological institutes and certified appraisers.
