Introduction
Thailand diamond jewelry sales can sometimes be a deceptively complex process. Too many sellers think their diamonds are worth a fortune, only to find out how much money they lose when selling them. In reality, however, loss in value does not usually occur due to the diamond — rather, it results from ignorance, an unclear market and compromising who you sell to. This is where teaming up with professional experts like Bkk Diamond becomes important to secure the actual value of your possession.
Knowing how the market works is the best way to avoid common pitfalls and minimize your return. Here, we reveal the top reasons why most Thais do not get full value for their diamonds—and clear steps to help you sell your diamond with confidence.
The Most Common Reasons Why Sellers Lose Value on Diamond Market
1. Flaw in Understanding of Diamond Grading
When it comes to choosing the best possible buyer of your diamond, many sellers tend to go into the market without comprehending diamonds’ grading factors- Cut, Color, Clarity and Carat weight (the 4Cs). Sellers would not be equipped to know the fair market value for their jewelry without this data.
The price of uncertified diamonds or those without a trusted grading report is usually lower since the customers need to estimate quality instead of trusting confirmed data.
2. Relying on Non-Specialist Gold Shops
One of the most common errors is selling diamond jewelry to gold stores instead of accredited diamond buyers. Gold buyers think the way to test a diamond’s “authenticity” is to ask, “What’s its gold weight?” The majority of gold buyers are only interested in your gold (not really your diamonds) and thus make extremely low offers.
Gold shops often:
- Lack gemological expertise
- Take diamonds out of settings, and then undervalue them
- Offer fixed pricing instead of evaluating the diamond properly
Experienced diamond buyers such as Bkk Diamond utilize accurate gemological instruments and adhere to international pricing classifications so that sellers do not get ripped off with lowball estimates.
3. Due to lack of GIA certificate or documents
A GIA certification (or equivalent grading report) could add thousands of dollars to the selling price of your diamond. Without it, buyers must take on more risk, meaning they will generally lower their offer to account for uncertainty.
Countless sellers are unwittingly giving up 20–40% of their value because they can’t prove it in negotiations.”
4. Emotion Pricing Vs Market Pricing
Diamonds typically have sentimental value such as in engagement rings or family jewelry. But sentiment is not the driver of any real market demand.
Many sellers want more than they can realistically get and so they become frustrated or make mistakes when it becomes apparent they will not get what they believe is fair value.
Learning to wrap your head around market pricing — and getting a transparent valuation from the pros — paves the way for realistic expectations.
5. Falling for False Promotions or “Instant Cash” Ads
There are also some online buyers that employ heavy advertising in an aggressive attempt to reel in sellers by setting high offer expectations. But offers like those, behind the scenes, can be laced with:
- Hidden fees
- Price reductions after inspection
- Aggressive as you can-be tactics to get a fast sale
It’s because of these misleading tactics that many sellers are willing to take offers tens—sometimes even hundreds—of thousands below the actual value of their home.
