Gold Purity Testing and Valuation in Kukatpally — Understand the Assessment
At Rithika Gold, purity testing is performed openly in front of you — using professional XRF (X-Ray Fluorescence) technology. You can watch the machine measure your gold's composition in real time and ask questions at every step.
Understanding Gold Purity Testing
"Karat" is the measure of gold purity. Pure gold is 24 karat. Most jewellery in India is 22K or 18K — meaning it contains other metals alloyed to improve durability. The gold purity level directly determines how much of your ornament's weight is actual gold and therefore what payment you receive when selling.
Understanding how purity is tested gives you confidence that you are receiving a fair valuation. At Rithika Gold, we want you to understand what happens to your gold — not just trust us blindly.
| Karat | Fineness | Gold Content | Common Use |
|---|---|---|---|
| 24K | 999.9 | ~99.99% | Investment coins & bars |
| 22K | 916 | ~91.6% | Indian jewellery (standard) |
| 18K | 750 | 75% | Fine jewellery, rings |
| 14K | 585 | 58.5% | Export jewellery |
Method 1: XRF (X-Ray Fluorescence) Karat Testing
XRF is the primary testing method at Rithika Gold. We use the Aczel Cube XRF karat analyser — a professional-grade instrument used across the refining, banking, and precious metals industries.
How it works
The XRF machine directs a focused X-ray beam at your gold item. The gold atoms in the metal absorb the energy and re-emit it as secondary X-rays at characteristic wavelengths. The detector measures these wavelengths and calculates the precise percentage of gold, silver, copper, and other metals present.
The XRF reading
An XRF reading does not require removal of a metal sample. Any proposed preparation, sampling or other procedure should be explained separately before you consent.
What it shows
The machine reports composition at the tested area. We explain how to interpret the result, what may limit its relevance to the whole item and how assessment affects the valuation.
Why XRF is the preferred standard
XRF can provide an initial assessment without removing a sample for that reading. The result must be interpreted alongside the item's construction and condition; it is not a certificate of uniform purity throughout the piece.
Method 2: Fire Assay and Homogeneity Testing
XRF readings need to be considered alongside the item itself. Antique ornaments, plated items, repairs or surface treatments can require further assessment. If sampling or fire assay is proposed, ask why it is needed and what will happen to your item before giving consent.
Fire assay is done only with your knowledge and consent
Melting your gold item changes it permanently. Before any fire assay is performed, we explain why it may be needed, what will happen to the piece, and what the expected outcome is. You can always decline and keep your gold.
What is fire assay?
Fire assay involves melting a sample or the entire item at high temperature to produce a homogeneous alloy. A small sample from the melt is then tested for precise gold content. Because the gold has been thoroughly mixed, the reading represents the true overall purity of the piece — not just the surface.
Why homogeneity matters
Some gold items — particularly older pieces or those repaired multiple times — may have uneven gold distribution. The outer surface might be 22K while inner sections are at a different karat. XRF reads the surface; fire assay reads the average true composition throughout.
When fire assay is discussed
Our team will suggest fire assay only when XRF gives an unusually low reading for a piece that appears visually higher karat, or when the item's construction makes it likely that surface composition differs from the core.

Gold testing near KPHB and JNTU
Where can I get gold purity testing near JNTU or KPHB?
Visit Rithika Gold near Kukatpally Metro for XRF gold purity testing. Our team explains the gold content and how it affects valuation. XRF measures surface composition; items with plating or uneven alloys may need further assessment.
What is the difference between 916 gold and 24-carat gold?
916 indicates 91.6% gold content and is commonly used for 22-carat jewellery. MMTC-PAMP 999.9 fine gold coins and bars are 99.99% gold and are commonly described as 24-carat. Testing helps establish the actual gold content of an item offered for sale.
What can a gold-purity reading tell me about a selling offer?
A purity assessment helps explain the metal being valued; it is not a price guarantee on its own. XRF measures the composition at the tested area. Coatings, solder, construction and differences between components can affect how representative that reading is. Ask how the result, eligible net metal weight and applicable buying rate are used together in your quotation.
- Mention repairs, plating, stones or mixed components before testing. A 916 stamp and an XRF reading provide different kinds of information.
- Ask whether the item needs checks beyond the initial reading. Any proposed sampling or melting should be explained, including its consequences, before you give consent.
- Confirm the applicable assessment arrangements and any charges. Request an explanation of the result before deciding whether to sell; testing does not oblige you to accept an offer.
