“Steve provided the extra information about how he arrived at the value he quoted for the diamond ring I was selling, He was knowledgeable, friendly, and patient in the process. He showed me how to use the loupe to view the diamond and pointed out the issues that affected the quality of the diamond.
When I went to other diamond buyer businesses, they did not give me the details about why the gave the value they provided; they just gave me a price quote.
I feel Steve gave me a fair quote and in the end, his quote was the highest I received; I sold him the diamond ring. I highly recommend Steve to examine your diamond and give you a quote.”

The 4Cs
Diamond Carat Weight
A diamond’s weight is measured in carats. Typically, the larger a diamond is, the more valuable it is, however diamonds of equal weights may vary widely in price based on their cut grades, colors and clarities.
Diamond Color
White diamonds are graded for color using a score ranging from D to Z. The most popular colors for diamond jewelry range from D to K color because they tend to appear white when mounted. Fancy colored diamonds are stones with pigment concentrations past the color Z. These stones can command prices equal to or even above colorless diamonds. This color spectrum includes naturally tinted Yellow, Green, Orange, Red, Pink and Blue diamonds.
Diamond Clarity
At GIA, a diamond is assigned a clarity grade based on natural inclusions and blemishes that are visible under 10X magnification. The diamond clarity grading scale starts from FL-IF (Flawless - Internal Flawless), VVS1-VVS2 (Very Very Slightly Included), VS1-VS2 (Very Slightly Included), SI1-SI2 (Slightly Included) to I1-I2 & I3 (Included).
Diamond Cut
The single most important factor in determining a diamond’s brilliance is its cut. Ideal cut diamonds, regardless of color and clarity, typically out shine higher grade stones with poor cut grades. Well cut diamonds more consistently hold their value than any other and can often command a premium.
